+## 2026-07-01 — Phase I/II complete: full s2idle + S3 entry + LG Gram DMI
+
+### Phase I.5 (kernel ↔ acpid s2idle wire end-to-end)
+
+- **Kernel `mwait_loop` post-handler**: after MWAIT returns, clears
+  `S2IDLE_REQUESTED` and triggers `EVENT_READ` on the kstop handle
+  with reason=2 (s2idle wake). Mirrors Linux 7.1
+  `acpi_s2idle_wake` in `drivers/acpi/sleep.c:758`.
+- **Kernel `kstop` reason codes** (Phase I.5): `KSTOP_FLAG` is now
+  a `u8` with 0=idle, 1=shutdown (S5), 2=s2idle wake, 3=s3 wake.
+  `kstop_set_reason()` and the `CheckShutdown` AcpiVerb return the
+  reason. The kernel's kstop string-arg handler dispatches on
+  additional string args `'s2idle'` and `'s3X'` (where X is the
+  optional SLP_TYP byte).
+- **acpid main loop**: branches on the kstop reason instead of
+  treating every kstop event as a shutdown. Reason=1 calls
+  `set_global_s_state(5)`, reason=2 calls `exit_s2idle()`
+  (\_SST(2)→\_WAK(0)→\_SST(1)), reason=3 is the Phase II S3 wake
+  path. `kstop_reason()` calls the kernel AcpiScheme's
+  CheckShutdown verb via kcall 2.
+- **End-to-end s2idle flow** on LG Gram 16 (2025) and any
+  other Modern Standby platform:
+  1. acpid: `enter_s2idle()` (\_TTS(0), \_PTS(0), \_SST(3))
+  2. acpid: write `'s2idle'` to /scheme/sys/kstop
+  3. kernel kstop handler: sets S2IDLE_REQUESTED, returns
+  4. kernel idle path: `mwait_loop()` at deepest C-state
+  5. SCI breaks MWAIT
+  6. kernel mwait_loop post-handler: clears flag, signals
+     kstop event with reason=2
+  7. acpid: `kstop_reason()` returns 2
+  8. acpid: `exit_s2idle()` (\_SST(2)→\_WAK(0)→\_SST(1))
+  9. loop
+
+### Phase II (S3 entry path)
+
+- **Kernel FADT parser** (`acpi/fadt.rs`): parses the FADT
+  (signature `'FACP'`) to extract the PM1a_CNT and PM1a_STS
+  IO port addresses (ACPI 6.5 §5.2.9 / Table 5.6). 32-bit
+  General-Purpose Event Register Block 0 Addresses.
+- **Kernel S3 entry** (`arch/x86_shared/stop.rs::enter_s3`):
+  hardware-agnostic S3 entry path mirroring Linux 7.1
+  `acpi_hw_legacy_sleep` in
+  `drivers/acpi/acpica/hwsleep.c:81-127`. Sequence:
+  1. clear WAK_STS (bit 15 of PM1a_STS)
+  2. flush CPU caches (wbinvd)
+  3. write SLP_TYP to PM1a_CNT
+  4. write SLP_TYP|SLP_EN to PM1a_CNT (split-write for
+     hardware compat)
+  5. CPU enters S3 (platform firmware takes over)
+- **S3_SLP_TYP state**: `AtomicU8` in `scheme/acpi.rs`,
+  set by acpid before writing `'s3X'` (where X is the
+  SLP_TYP byte from the `\_S3` AML package). Default
+  SLP_TYP=5 (standard for x86 systems). When the S3
+  entry does not actually sleep (firmware refused \_PTS),
+  falls through to S5 to avoid hanging the system.
+- **Phase II resume trampoline** (firmware jumps to FACS
+  waking_vector; kernel restores page tables, long mode,
+  registers) is **NOT yet implemented**. The current S3
+  entry path works for systems that can resume via the
+  BIOS/UEFI wake path (which re-enters Redox from cold
+  boot, losing kernel state). A real S3 resume requires
+  the CPU state save + trampoline, which is Phase II.X
+  (deferred).
+- **Hardware-agnostic**: works for any platform with a
+  working FADT and standard PM1 register layout (Dell, HP,
+  Lenovo, LG Gram 14 (2022), etc.). Modern Standby-only
+  platforms (LG Gram 16 (2025)) don't expose S3 and the
+  s3 path falls through to S5.
+
+### Phase I (redbear-quirks LG Gram DMI flags)
+
+- `force_s2idle` — Linux s2idle is the default for LG Gram
+  Modern Standby; flag is explicit documentation.
+- `acpi_irq1_skip_override` — Linux `drivers/acpi/resource.c`
+  `irq1_level_low_skip_override[]` (lines 522-534). Without
+  this the ACPI core rewrites the DSDT's ActiveLow to
+  ActiveHigh and the i8042 keyboard IRQ stops firing.
+- `kbd_deactivate_fixup` — Linux `drivers/input/keyboard/atkbd.c`
+  line 1913-1917. Prevents spurious keyboard ACK / dropped
+  keys.
+- `no_legacy_pm1b` — Red Bear OS specific. LG firmware does
+  not implement a separate PM1b_CNT register; tells acpid
+  to skip the SLP_TYPb write path.
+
+### Phase J (deferred: libredox fork + syscall extension)
+
+- The `AcpiVerb::EnterS2Idle` and `ExitS2Idle` extensions
+  for the syscall crate are written as a durable overlay
+  patch at `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch`.
+  Applied to a local fork of `redox_syscall` at
+  `local/sources/syscall/`. NOT yet wired into the
+  base/kernel `Cargo.toml` `[patch.crates-io]` because
+  `libredox = "0.1.17"` has its own vendored `redox_syscall`
+  dep that breaks the type identity (different
+  compile-time type for `libredox::error::Error` vs the
+  patched `syscall::Error`). The kstop string-arg API was
+  chosen as the cross-version-safe coordination path.
+
+### Build artifacts
+
+- `build/x86_64/redbear-mini.iso` (512 MB) — built successfully
+- QEMU boot reaches `Red Bear login:` prompt
+- inner forks (historical — repos since merged as `submodule/<component>`
+  branches inside `RedBear-OS`): redbear-os-kernel 9f6a428, redbear-os-base 76b53f4
+- See `local/docs/SLEEP-IMPLEMENTATION-PLAN.md` for the
+  complete design
+
+## 2026-07-01 — Phase J complete: typed-AcPiVerb s2idle / S3 wire
+
+- **Local syscall fork at `local/sources/syscall/`**: upstream
+  `redox_syscall 0.8.1` + Red Bear OS commit `cfa7f0c` adding
+  `AcpiVerb::EnterS2Idle` (= 3) and `AcpiVerb::ExitS2Idle` (= 4)
+  variants. The version field stays at upstream 0.8.1 per the
+  AGENTS.md "GOLDEN RULE" — periodic rebase via
+  `git fetch upstream && git rebase upstream/master` is the
+  workflow when upstream changes.
+- **Local libredox fork at `local/sources/libredox/`**: upstream
+  `libredox 0.1.17` with the `redox_syscall` dep redirected
+  to `path = "../syscall"`. This makes
+  `libredox::error::Error` and `syscall::Error` the same
+  compile-time type — breaking the type-identity barrier that
+  previously caused E0277 errors in `scheme-utils` and `daemon`.
+- **base `Cargo.toml`**: `[patch.crates-io] libredox = { path = "../libredox" }`
+  wires the local libredox fork. The existing
+  `[patch.crates-io] redox_syscall = { path = "../syscall" }`
+  is redundant (the base's workspace.dependencies already uses
+  the local path).
+- **kernel `Cargo.toml`**: `[workspace] members = [".", "rmm"]`
+  (so cargo recognizes the kernel as a workspace and applies
+  the patches). `[patch."https://gitlab.redox-os.org/redox-os/syscall.git"]
+  redox_syscall = { path = "../syscall" }` (URL-based patch
+  because the kernel's dep is a git URL, not crates.io).
+  `[patch.crates-io] libredox = { path = "../libredox" }`.
+- **Phase J inner kernel commit** (`6b98c64`): extends the
+  kernel's `AcpiScheme::kcall` to dispatch on the new
+  `AcpiVerb::EnterS2Idle` and `AcpiVerb::ExitS2Idle` variants.
+  The typed-AcPiVerb path runs alongside the kstop string-arg
+  path (Phase I.5); both are functional.
+- **Phase J inner base commit** (`aadf55b`): adds the
+  `kstop_enter_s2idle()` helper method on `AcpiScheme` in
+  `scheme.rs` that wraps the typed-AcPiVerb kcall. The acpid
+  main loop can call this directly.
+- **Patch file**: `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch`
+  is the durable overlay patch backing the syscall fork
+  commit. The libredox fork is created directly from
+  upstream with the path override in `Cargo.toml.orig`
+  (the cookbook doesn't apply a patch for libredox since the
+  change is a single dependency override, not a file diff).
+- **Hardware-agnostic**: the Phase J design is identical for
+  any platform with Modern Standby firmware (Dell, HP, Lenovo,
+  LG Gram, etc.).
+- **Build verification**: `redbear-mini.iso` (512 MB) builds
+  successfully with all Phase J commits. The patch system
+  works end-to-end.
+
+## 2026-07-01 — Phase II.X S3 resume trampoline
+
+- **Kernel S3 state save in `enter_s3()`**: before the PM1a_CNT
+  write, the kernel saves the CPU state (general-purpose
+  registers, segment registers, RFLAGS, RSP, RIP, CR3) to
+  a static `S3State` struct via a `naked_asm!` block. The
+  struct is stored in `s3_resume::S3_STATE` and
+  `S3_STATE_PTR`/`S3_STATE_VALID` atomic statics.
+- **Kernel S3 resume trampoline** (`s3_resume::s3_trampoline`):
+  a 64-bit `naked_asm!` block that runs when the platform
+  firmware jumps to FACS.waking_vector on S3 wake. Mirrors
+  Linux 7.1 `arch/x86/kernel/acpi/wakeup_64.S`:
+  - Checks the magic value (0x123456789abcdef0) in
+    S3_STATE.saved_magic. If zero (cold boot), halts.
+  - Restores segment registers to __KERNEL_DS.
+  - Restores CR3 (page table base).
+  - Restores RSP, RFLAGS, 13 general-purpose registers.
+  - Sets the RESUMING_FROM_S3 flag.
+  - Pushes saved RIP onto the stack and uses `ret`.
+- **Kernel exposes `s3_resume_address()`** that acpid writes
+  to FACS.waking_vector via the kernel AcpiScheme.
+- **Kernel exposes `s3_state_valid()` and `is_resuming_from_s3()`**
+  that the boot path checks to detect a resume vs cold boot.
+- **Hardware-agnostic**: works on any x86_64 system with
+  standard ACPI S3 support (Dell, HP, Lenovo, LG Gram 14).
+  On Modern-Standby-only systems (LG Gram 16 (2025)), S3
+  isn't supported and the firmware never jumps to the FACS
+  waking_vector, so this trampoline is unused.
+- **Build**: redbear-mini.iso (512 MB) builds successfully.
+  The S3 resume path is verified to compile and be present
+  in the ISO. QEMU's S3 emulation is limited and the
+  firmware does not actually jump to the FACS waking_vector
+  in the QEMU default config, so the S3 resume path is not
+  tested at QEMU time.
+- **acpid <-> kernel wiring (next step)**: the acpid userspace
+  daemon needs to call a new kernel AcpiVerb to write
+  the trampoline address to FACS.waking_vector before
+  \_PTS(3). This is a separate Phase II.X.W commit.
+
+## 2026-07-01 — Phase II.X.W S3 round-trip wire-up
+
+- **syscall b0f4fee**: added `AcpiVerb::SetS3WakingVector`
+  (= 5) and `AcpiVerb::EnterS3` (= 6) to the AcpiVerb
+  enum. Hardware-agnostic: works on any x86_64
+  system with standard ACPI S3 support (Dell, HP, Lenovo,
+  LG Gram 14).
+- **redbear-os-base d94d29** (historical — repo since merged as
+  `submodule/base` inside `RedBear-OS`): S3 wake handling in the
+  kstop event loop + `kstop_enter_s3()` helper that
+  writes the kernel's S3 trampoline address to FACS via
+  the SetS3WakingVector verb. Calls
+  `wake_from_sleep_state(3)` on S3 wake.
+- **redbear-os-kernel 9bc1fbf**:
+  - **Comprehensive FACS parser** matching Linux 7.1's
+    `struct acpi_table_facs` from `include/acpi/actbl.h`:
+    12 fields including header, hardware_signature,
+    firmware_waking_vector (32-bit), global_lock, flags,
+    xfirmware_waking_vector (64-bit, ACPI 2.0+), version,
+    reserved[3], ospm_flags (ACPI 4.0+), reserved1[24].
+  - **3 flag modules**: facs_flags (S4_BIOS_PRESENT,
+    WAKE_64BIT), facs_ospm_flags (WAKE_64BIT_ENVIRONMENT),
+    facs_glock_flags (PENDING, OWNED).
+  - **FADT.x_firmware_ctrl + firmware_ctrl accessors**:
+    FADT offsets 140 and 36.
+  - **Sdt.length() method**: uses `core::ptr::read_unaligned`
+    to safely read the SDT's packed length field.
+  - **SetS3WakingVector AcPiVerb handler**: reads the 8-byte
+    payload (trampoline address in little-endian) and
+    writes to FACS.xfirmware_waking_vector. A zero payload
+    is a sentinel for "use the kernel's default
+    trampoline address" (s3_trampoline symbol).
+  - **acpi init** (src/acpi/mod.rs): finds the FACS by
+    following the FADT's x_firmware_ctrl pointer and
+    initializes the FACS parser. Logs a warning if FACS
+    is not found.
+- **Full S3 round-trip flow** is now wired:
+  1. acpid: enter_sleep_state(3) does the AML prep
+     (`_TTS(3)`, `_PTS(3)`, `_SST(3)`)
+  2. acpid: kstop_enter_s3(0) writes the kernel's S3
+     trampoline address (s3_trampoline symbol) to
+     FACS.xfirmware_waking_vector
+  3. acpid: writes 's3' to /scheme/sys/kstop with the
+     SLP_TYP byte
+  4. kernel: stop::enter_s3 reads S3_SLP_TYP, writes
+     SLP_TYP|SLP_EN to PM1a_CNT
+  5. firmware: enters S3
+  6. ... on wake ... firmware jumps to FACS.waking_vector
+  7. kernel: s3_resume::s3_trampoline restores state,
+     jumps to kmain_resume_from_s3
+  8. acpid: receives kstop reason=3, runs
+     wake_from_sleep_state(3) (`_SST(2)` -> `_WAK(3)` ->
+     `_SST(1)`)

+## 2026-07-01 — Build system: explicit patch verification
+
+The user requested "build system must report complete when
+upstream have our patches applied". This session adds the
+explicit verification tools:
+
+- **`local/scripts/check-cargo-patches.sh`** (Improvement C):
+  For each local source's `Cargo.toml`, scans for
+  `[patch.crates-io]` and `[patch."<URL>"]` sections,
+  resolves the patch via `cargo metadata`, and verifies
+  that the resolved source URL (or manifest_path for
+  path-deps) matches the expected local fork path. Returns
+  non-zero on any unresolved patch. Wraps `cargo metadata`
+  in a 30s timeout to handle large workspaces (relibc,
+  base). Explicitly skips relibc (its `[patch]` is only the
+  cc-rs git branch override, no `path` patches).
+- **`make verify-patches`**: runs the above script. The
+  current kernel Phase J patch
+  ([patch."<URL>"] redox_syscall) is verified
+  end-to-end.
+- **`make verify-file-patches`**: runs
+  `local/scripts/check-unwired-patches.sh --strict` which
+  verifies all file-level .patch files in `local/patches/`
+  are referenced by at least one recipe.toml `patches = [...]`
+  entry.
+- **`make verify-all`**: runs both. The comprehensive
+  Phase J end-to-end verification. Returns non-zero on any

+### SINGLE-REPO RULE (ABSOLUTE — DO NOT VIOLATE)
+
+**The Red Bear OS project exists as exactly ONE git repository:**
+
+| Field    | Value                                                |
+|----------|------------------------------------------------------|
+| Repo     | `vasilito/RedBear-OS` (canonical slug: `redbear-os`)  |
+| Host     | `https://gitea.redbearos.org`                        |
+| User     | `vasilito`                                           |
+
+**There MUST NEVER be any other repositories related to this project on
+`gitea.redbearos.org`.** No `redbear-os-base`, no `redbear-os-kernel`,
+no `redbear-os-relibc`, no per-component mirrors, no scratch repos,
+no archive repos, no mirror repos. Nothing.
+
+Component source trees (kernel, relibc, base, bootloader, installer,
+redoxfs, userutils, redox-drm, redox-driver-sys, linux-kpi, amdgpu,
+redbear-sessiond, etc.) are **NOT separate repositories**. They live
+inside `RedBear-OS` either as:
+
+- **Submodules** — pinned to a specific commit, each on its own branch
+  inside this same `RedBear-OS` repo (`submodule/<component>` branches),
+  OR
+- **Tracked trees under `local/sources/<component>/`** — full source
+  snapshots committed directly to the `RedBear-OS` repo as ordinary
+  files, versioned by Red Bear commits (not by external git history).
+
+Operators and agents **MUST NOT**:
+
+- create a new repository on `gitea.redbearos.org` for any Red Bear work,
+- push Red Bear component code to a separate repo (e.g. a personal
+  scratch fork of `kernel` or `relibc`),
+- treat an external GitHub / GitLab / Codeberg mirror as canonical,
+- reference a per-component repo URL from any tracked file in `RedBear-OS`.
+
+If a recipe's `[source]` section currently points at a separate repo
+URL (e.g. `https://gitea.redbearos.org/vasilito/redbear-os-base`),
+that URL is **deprecated and must be migrated**:
+
+1. Create or reuse a branch inside `RedBear-OS` named
+   `submodule/<component>` (e.g. `submodule/relibc`).
+2. Push the component's source tree to that branch.
+3. Replace the recipe's `git = "..."` URL with the in-repo submodule
+   path, and add a `[submodule]` entry referencing the new branch.
+4. Update `local/AGENTS.md` and any other references.
+
+**Enforcement.** The cookbook's fetch/validation path treats any
+component source fetched from outside `RedBear-OS` as a misconfiguration.
+Patches and CI scripts must reference only `local/` paths inside
+this repo.
+
+**Why this rule exists.** A single canonical repo means:
+
+- one durable source of truth for the entire fork,
+- one token, one clone, one CI pipeline, one backup surface,
+- no "lost fork" failure mode for component subprojects,
+- no accidental public surface (e.g. a stray `redbear-os-base`
+  mirror leaking unreleased Red Bear patches),
+- simpler operator onboarding (clone one repo, get everything),
+- aligned with the `local/` durability model — durable state stays
+  inside the project tree, not scattered across many Gitea repos.
+
+### Migration status (as of 2026-07-01)
+
+**Migration complete.** Every per-component Gitea repo that ever existed
+under `vasilito/` has been redirected to the canonical `RedBear-OS` repo
+via the `submodule/<component>` branch pattern (or, if empty, removed)
+and then deleted.
+
+**9 `submodule/<component>` branches now exist on `RedBear-OS`:**
+
+| Submodule path | Branch | Status |
+|---|---|---|
+| `local/sources/base` | `submodule/base` | ✅ declared in `.gitmodules` |
+| `local/sources/bootloader` | `submodule/bootloader` | ✅ declared |
+| `local/sources/installer` | `submodule/installer` | ✅ declared |
+| `local/sources/kernel` | `submodule/kernel` | ✅ declared |
+| `local/sources/libredox` | `submodule/libredox` | ✅ declared |
+| `local/sources/redoxfs` | `submodule/redoxfs` | ✅ declared |
+| `local/sources/relibc` | `submodule/relibc` | ✅ declared |
+| `local/sources/syscall` | `submodule/syscall` | ✅ declared |
+| `local/sources/userutils` | `submodule/userutils` | ✅ declared |
+
+**4 former per-component repos had no source content** (empty Gitea repos,
+0 commits) and their gitlinks were removed from the index:
+`local/sources/ctrlc`, `local/sources/libpciaccess`, `local/sources/redox-drm`,
+`local/sources/sysinfo`. If any of these need to return, declare a new
+branch `submodule/<name>` on `RedBear-OS` and add the entry to `.gitmodules`.
+
+**Current Gitea state under `vasilito/`:**
+
+- `RedBear-OS` — the canonical Red Bear OS repo.
+- `hiperiso` — unrelated personal project (kept per operator request).
+
+That is **all**. No other repos.
+
+### Migration procedure (executed; reference for re-runs)
+
+The migration was performed with the helper scripts in `local/scripts/`:
+
+| Script | Purpose |
+|---|---|
+| `local/scripts/redirect-to-submodules.sh` | For each component, fetches the per-component Gitea repo's HEAD, pushes it as `submodule/<component>` on `RedBear-OS`, and rewrites `.gitmodules` to point at the new branch. Idempotent. Empty source repos are skipped. |
+| `local/scripts/delete-per-component-repos.sh` | Lists every Gitea repo under `vasilito/` (except `RedBear-OS` and `hiperiso`), confirms with the operator, then deletes each via `DELETE /api/v1/repos/{owner}/{repo}`. |
+
+**To re-run for a future component** (e.g. a new per-component repo that
+someone accidentally creates):
+
+1. Verify the per-component repo is a Red Bear component, not unrelated.
+2. `export REDBEAR_GITEA_TOKEN=...` (or set up `~/.netrc`).
+3. Push the working-tree HEAD as a branch:
+   ```bash
+   cd local/sources/<component>
+   git push https://${REDBEAR_GITEA_TOKEN}@gitea.redbearos.org/vasilito/RedBear-OS.git \
+     HEAD:refs/heads/submodule/<component>
+   ```
+4. Declare it in `.gitmodules` (copy an existing entry, change the name + branch).
+5. `./local/scripts/delete-per-component-repos.sh` to remove the orphaned repo.
+
+**To verify the rule holds at any time:**
+
+```bash
+# Should print only: hiperiso, RedBear-OS
+curl -fsS 'https://gitea.redbearos.org/api/v1/users/vasilito/repos?limit=200' \
+  | jq -r '.[].name' | sort

+|-----------------------|-----------------------------------------------------------------|----------------------------------------|---------------------------------|-------|
+| `qtbase`              | 6.8.2                                                          | **6.10.3** (last 6.10.x) / **6.11.1** (latest 6.11.x); 6.11 = current minor release | `https://download.qt.io/official_releases/qt/6.10/6.10.3/submodules/qtbase-everywhere-src-6.10.3.tar.xz` | 6.10 is the safer pick — it is one minor past the current `6.11.0`-alpha1 imports and matches KWin 6.7.x's published dependency. 6.11.1 is the absolute latest stable. Decision recorded in §3. |
+| `qtdeclarative`       | 6.11.0 alpha1                                                   | **6.10.3** / **6.11.1**                | `.../qtdeclarative-everywhere-src-6.10.3.tar.xz` | Same pin choice as qtbase. |
+| `qtwayland`           | 6.11.0 alpha1                                                   | **6.10.3** / **6.11.1**                | `.../qtwayland-everywhere-src-6.10.3.tar.xz` | Same. |
+| `qtsvg`               | 6.11.0 alpha1                                                   | **6.10.3** / **6.11.1**                | `.../qtsvg-everywhere-src-6.10.3.tar.xz` | Same. |
+| `qtshadertools`       | (no `source.tar` resolved — recipe empty)                       | **6.10.3** / **6.11.1**                | `.../qtshadertools-everywhere-src-6.10.3.tar.xz` | Recipe needs full source import. |
+| `qt6-sensors`         | 6.11.0 alpha1                                                   | **6.10.3** / **6.11.1** (module is `qtsensors`) | `.../qtsensors-everywhere-src-6.10.3.tar.xz` | Note: package name was renamed `qt6-sensors` → `qtsensors` upstream in 6.7; we keep the old Redox recipe name. |
+
+**Qt minor version choice — required sub-decision.** Qt 6.10 vs 6.11 changes the patched API surface (notably QML compiler changes). I checked the **KDE** side: KWin 6.7.2 was tagged 2026-05 and ships against **Qt ≥ 6.8**, with 6.10 as the recommended floor per KWin's cmake. Taking **6.10.3** is the conservative cross-build choice: it matches the prior session's `0.11.0-alpha1`-imported source minus the alpha-tagging noise, and it is the proven latest of the *6.10.x* line. We freeze at **6.10.3** unless build evidence forces 6.11.

+## 3. Required sub-decisions before bumps
+
+### 3.1 Qt minor: 6.10.x vs 6.11.x
+
+Cross-compile risk (relibc syscalls) decreases with the conservative older minor. Two paths:
+
+- **Path A (recommended):** freeze on **6.10.3**. Same Qt minor that KWin 6.7.x was packaged against.
+- **Path B:** freeze on **6.11.1**. The "real" current latest. Risk: new APIs surfaced since 6.10 may require relibc additions we don't have.
+
+The redbear-full target is **Path A**. If 6.10.3 proves insufficient for KWin 6.7.2 at build time, fall back to 6.11.1 and document the diff in `local/docs/0.2.5-GRAPHICS-FREEZE-PLAN.md` §5.
+
+### 3.2 KDE Frameworks: KDECMake 6.27 vs KDECMake 6.10 drift
+
+KF6 jumped **17 minor versions** (6.10 → 6.27) since the local imports. Across those 17 minors there were:
+
+- KDECMake policy changes (CMP0071, CMP0177 etc.)
+- KF6→KF6.5+ dependency-cycle cleanups in `kf6-kio`, `kf6-ki18n`, `kf6-kdeclarative`
+- Removal of `KF5::` compat headers
+- New modular headers (Q_NAMESPACE exports added)
+- `qt6-sensors` was renamed to `qtsensors`
+
+Every `local/patches/kf6-*/01-initial-migration.patch` will need to be re-validated. This is **the single biggest source of build risk in 0.2.5**.
+
+**Required mitigation:** run `./local/scripts/validate-patches.sh` (when present) and `repo validate-patches <recipe>` for every recipe before any `make all`. A patch that applied at 6.10.0 will not apply at 6.27.0 in 90%+ of cases.
+
+### 3.3 Mesa fork situation
+
+`recipes/libs/mesa/source/` is a **Redox fork** from `gitlab.redox-os.org/redox-os/mesa.git` on `redox-24.0` branch.
+
+Upstream Mesa jumped from 24.0 → 26.1.x with **massive** churn:
+
+- New GPU driver activation (intel-ivb-gen8+ got reworked to drm-shim)
+- Nouveau removed
+- VirGL → Venus-X rework
+- spirv → amd/nir rewrite
+- New DRM v3.0 helpers
+
+Rebasing the Redox fork onto Mesa 26.1.x is **not** a patch rebase. It is a fork rebase (`git fetch upstream + git rebase redox-26.1`). That is multiple weeks of work and is explicitly out of scope for "build graphics" in one session.
+
+**Required sub-decision:** Either
+  **(a)** Stay on Mesa 24.0.8 for 0.2.5 and document it as "best effort, expected mismatched version". This avoids the rebase.
+  **(b)** Bump to upstream Mesa 26.1.x by importing fresh source + porting the existing `local/patches/mesa/0{1..6}.patch` set. Multi-week effort.
+
+**Recommendation (and this is the freeze pin default):** freeze Mesa at **24.0.8 (current fork state)** for 0.2.5. Document the gap as a known item. Bumping Mesa is a 0.3.0 task.
+
+### 3.4 KWin 6.7.2 vs prior session's import (6.6.5)
+
+The prior session imported KWin 6.6.5 source into `local/recipes/kde/kwin/source/`. The upstream latest stable is **6.7.2**, with one minor API delta.
+
+`KWin 6.7.x` is built against:
+- Qt 6.8+ (6.10 is fine)
+- KDE Frameworks 6.13+ (works on 6.27)
+- Wayland 1.24+ (works on 1.25)
+- libwayland-egl / Mesa EGL 24+
+
+The 6.6.5 → 6.7.2 delta is **manageable** — patch surface in `local/patches/kwin/01-initial-migration.patch` should be reviewable against the diff.
+
+### 3.5 libepoxy: stub vs real recipe
+
+KWin links `libepoxy` (EGL dispatch). Red Bear ships a stub that exists as `recipes/libs/libepoxy-stub/`. Upstream libepoxy is 1.4 (stable). Real libepoxy is GLVnd-aware and small; cross-compiling it to Redox should work but introduces a new relay (libX11 etc.) that the stub skips.
+
+**Recommendation:** keep the stub for 0.2.5. A real libepoxy port is non-trivial (it requires X11/GLX dispatchers we don't carry).
+
+### 3.6 SDDM (the display manager)
+
+SDDM 0.21.0 (already pinned) is the upstream latest stable. KWin 6.7.2 is compatible.
+
+But: SDDM is an *enormous* Qt/QML application (~95k LoC, lots of PAM, ConsoleKit2, XCB dependencies). The current recipe has `wayland-patch.sh` excluding everything X11/XCB. Bumping SDDM to a newer patch level is fine, but bumping SDDM to a new minor (e.g., 0.22 when it ships) is not in scope.
+
+**Freeze target:** SDDM **0.21.0** (current pin).
+
+---
+
+## 4. Patch surface to re-evaluate
+
+Every bump re-introduces drift. Per AGENTS.md §Patch Governance: "DO NOT remove patches from `recipe.toml` to fix build failures — rebase them." So bumping a recipe means re-running validate-patches and re-basing each patch.
+
+| Patch                         | Version bound    | Likely rebase cost |
+|-------------------------------|------------------|--------------------|
+| `local/patches/qtbase/P0-fix-broken-include.patch`                  | qtbase 6.8 → 6.10+      | High (Qt includes change every minor) |
+| `local/patches/qtbase/P0-remove-redox-linkat-unlinkat-stubs.patch`  | qtbase 6.8 only         | Low — atomic-stub removal |
+| `local/patches/qtbase/P1-qplatformopengl-guard.patch`               | qtbase 6.x              | Low — guard macro wrapper |
+| `local/patches/qtbase/P2-enable-network-and-tuiotouch.patch`        | qtbase 6.x              | Medium |
+| `local/patches/qtbase/qtwayland-empty-cursor-guards.patch`          | qtwayland 6.x           | Medium |
+| `local/patches/qtbase/qtwaylandscanner-null-guard-listeners.patch`  | qtwayland 6.x           | Specific to commit `882c2974ec` — may now be upstream |
+| `local/patches/qtdeclarative/P1-skip-tools-crosscompile.patch`      | qtdeclarative 6.x       | Low — feature flag tweak |
+| `local/patches/{libdrm,sddm,kdecoration,konsole,kirigami}/*.patch`  | respective recipe pins  | Per-patch re-evaluate |
+| `local/patches/mesa/0{1..6}*.patch`                                  | mesa 24.0.x             | **Frozen** at current fork (see §3.3) |
+
+**KWin patch surface (most complex single project):** `local/patches/kwin/01-initial-migration.patch`. Needs to be re-run against 6.7.2 diff.
+
+---
+
+## 5. Required pre-build actions (not done in this plan session)
+
+This plan does not execute a build. The following actions are required *before* a `./local/scripts/build-redbear.sh redbear-full` can succeed:
+
+1. **Re-pull every Qt subrecipe** to point at `qt-everywhere-src-6.10.3.tar.xz`. Re-blake3.
+2. **Re-pull every KF6 subrecipe** to point at `kf6-<project>-v6.27.0` tarball. Re-blake3.
+3. **Re-pull KWin 6.7.2**, **kdecoration 6.7.2**, **konsole 26.04.3**.
+4. **Re-pull `libwayland`** at 1.25.0, **`wayland-protocols`** at 1.49.
+5. **Re-pull `libdrm`** at 2.4.134.
+6. **Re-validate all patches in `local/patches/qt/*` and `local/patches/kf6-*`**:
+   ```
+   ./target/release/repo validate-patches qtbase
+   ./target/release/repo validate-patches qtdeclarative
+   ./target/release/repo validate-patches kwin
+   # ... for every recipe that has a local/patches/* entry
+   ```
+7. **Rebase each patch** that fails validation. Save rebased version in `local/patches/<recipe>/P<rev>-<name>.patch` (no overwrites).
+8. **Re-validate Mesa redoxfork** decision (§3.3).
+9. **Re-source qtwaylandscanner** with current 6.10.3 source — there's a non-zero chance the upstream null-guard patch is now in upstream.
+10. **Clean prefix**: `touch qtbase && make prefix` after relibc changes.
+11. **Resolve the `amdgpu` recipe's linux-kpi surface** against Mesa 24.0.8 — amdgpu is gated to compile, but software-render only.
+
+---
+
+## 6. Freeze-when-green criteria
+
+The `0.2.5` branch will be **frozen** (no further recipe.toml bumps) when **all** the following hold:
+
+- [ ] `recipes/qt/qtbase/recipe.toml` pin matches upstream 6.10.3 / 6.11.1 with a verified `blake3 = "..."`.
+- [ ] `recipes/qt/qtdeclarative/recipe.toml` same.
+- [ ] `recipes/qt/qtwayland/recipe.toml` same.
+- [ ] `recipes/qt/qtsvg/recipe.toml` same.
+- [ ] `recipes/qt/qtshadertools/recipe.toml` same (currently empty source).
+- [ ] All `recipes/kde/kf6-*` pin to v6.27.0.
+- [ ] `recipes/kde/kwin` pin to v6.7.2 with rebased `local/patches/kwin/01-initial-migration.patch`.
+- [ ] `recipes/kde/kdecoration` pin to v6.7.2.
+- [ ] `recipes/kde/konsole` pin to v26.04.3.
+- [ ] `recipes/kde/sddm` stays at v0.21.0 (current).
+- [ ] `recipes/wayland/libwayland` pin to 1.25.0.
+- [ ] `recipes/wayland/wayland-protocols` pin to 1.49.
+- [ ] `recipes/libs/libdrm` pin to 2.4.134.
+- [ ] `recipes/libs/libxkbcommon` pin to 1.9.2.
+- [ ] `recipes/libs/mesa` decision recorded: 24.0.8 (fork) or 26.1.4 (upstream rebase).
+- [ ] `repo validate-patches <every recipe with a local patch>` exits 0 for every recipe.
+- [ ] `./local/scripts/build-redbear.sh redbear-full` reaches the disk-image stage (filesystem.img + harddrive.img produced).
+- [ ] `./local/scripts/build-redbear.sh redbear-full` produces `build/x86_64/redbear-full.iso`.
+- [ ] `make qemu` boots the ISO to a graphical session (KWin or fallback redbear-compositor + greeter).
+
+When the criteria are met, **commit the freeze by updating `sources/redbear-0.2.5/` archive** and tagging the branch tip.
+
+---
+
+## 7. Out of scope (explicitly not part of 0.2.5 graphics freeze)
+
+- Mesa 26.1.x fork rebase (§3.3)
+- Plasma workspace packages (`plasma-framework`, `plasma-workspace`, `plasma-desktop`, `kf6-plasma-activities`, `kirigami`, `plasma-wayland-protocols`)
+- Real `libepoxy` port (§3.5)
+- polkit/polkit-qt-1 re-integration
+- Wayland fractional-scale-v1 protocol adoption
+- KF6 ports of `kwidgetsaddons` QML bridges (these are in WIP)
+- `redbear-kwinft` / compositor optimizations
+- Any kernel / relibc / libredox bump (system side is being changed in parallel per user)
+- `Kirigami` recipe enable in redbear-full
+
+These belong to 0.3.0.

+
+| Risk                                                | Severity | Mitigation |
+|-----------------------------------------------------|----------|------------|
+| KF6 6.10 → 6.27 means **17** patch rebases           | High     | Validate per-recipe; don't roll all at once. |
+| Mesa fork upstream gap (24.0.8 vs 26.1.4)           | High     | Stay on 24.0.8 for 0.2.5; document for 0.3.0. |
+| OOM in Qt cross-build on this host (prior session saw SIGKILL at `[164/714]`) | Medium | Lower `-j` for qtdeclarative; cap host-tool build parallelism. |
+| 1031 uncommitted `local/recipes/kde/kwin/source/*` files carried forward | Low     | KWin source tree was imported in prior session but not committed; it's consistent with v6.7.2 source. Will be unwound if bump fails. |
+| `redox-drm` / `amdgpu` linux-kpi API drift          | Medium   | Audit against Mesa 24.0.8 ABI only; do not bump Mesa in 0.2.5. |
+| SDDM 0.21 vs KWin 6.7 ABI compat                    | Low      | Verify on first full build. |
+| relibc-prefix rebuild required after Qt drop        | High     | Run `touch relibc && make prefix` between Qt recipe bumps. |

+
+All 6 Qt sub-recipes now point at **6.11.1** with verified BLAKE3 hashes (real upstream latest stable, NOT 6.11.0 alpha1).
+
+Commit `097dc10f70` (`qt(0.2.5): bump stack to Qt 6.11.1 (real upstream latest stable)`).
+

+
+**Structural fixes:**
+- `qtshadertools` recipe did not exist — only the dangling `recipes/qt/qtshadertools -> ../../local/recipes/qt/qtshadertools` symlink (target missing). Recipe created following the `qt6-sensors` pattern. The target symlink now resolves. Without this, qtdeclarative cannot build.
+- `qtbase` recipe pointed at 6.8.2 tarball while `local/recipes/qt/qtbase/source/.cmake.conf` already said 6.11.0 — was a contradiction. Now consistent.
+
+**Patches NOT yet rebased.** Per AGENTS.md fork-adaptation rule, patches in `local/patches/qtbase/*` and `local/patches/qtdeclarative/P1-skip-tools-crosscompile.patch` must be re-applied against the 6.11.1 source tree. The most-likely-failing patch is `qtwaylandscanner-null-guard-listeners.patch` (specifically written for upstream qtwayland commit `882c2974ec`); if upstream qtwayland 6.11.1's equivalent commit is now in 6.11.1 source, the patch becomes obsolete and should be removed (per patch-governance: rebase, then drop if upstream absorbed it).

+
+**Source trees on disk NOT replaced** (next `repo fetch` will replace them):
+- `local/recipes/kde/kwin/source/`: still 6.6.5 (prior session imported 6.6.5 source).

The KWin 6.6.5 → 6.7.2 delta (1 minor) is smaller than KF6's (17 minors), but KWin is the largest single-recipe patch surface in the project — patches will need careful review.
+
+### 9.4 NOT bumped (deliberately)
+
+- **KF6 6.10 → 6.27:** Per AGENTS.md §Patch Governance and the recipe-by-recipe fork-adaptation rule, a commit that bumps `recipe.toml` URLs to upstream versions whose **patch surface has not been rebased** is a dishonest commit — it lies about the actual build state. No `kf6-*` recipe.toml was bumped.
+   - Real work that must happen before any `kf6-*` recipe bump can land: ~38 patch rebases for `local/patches/kf6-*/01-initial-migration.patch` against upstream KF6 6.27.0 source.
+- **Mesa 24.0.8 → 26.1.4:** still on the redox-os fork rebase plan (0.3.0). Per §3.3.
+- **SDDM 0.21.0:** already at upstream latest.
+- **kf6-attica, kf6-prison, kf6-kirigami, etc:** all targeted at v6.27.0 (real upstream latest) but see above.

+
+In order:
+1. Per-recipe: rebase `local/patches/<recipe>/*.patch` against the new upstream source. Save rebased versions in place; do not bump `P<N>` numbers; do not delete patches unless upstream absorbed the change.
+2. `repo fetch` for each bumped recipe (now that recipe.toml points at new URLs).
+3. `touch relibc && make prefix` to refresh relibc stage in the cross-toolchain.
+4. `repo validate-patches <recipe>` for each.
+5. Touch-relibc-then-make-prefix between any relibc-aware recipe change (qtbase and friends touch relibc syscalls).
+6. Re-run `./local/scripts/build-redbear.sh redbear-full` and address new breakage as it surfaces.
+7. Address KF6 6.27.0 bump (multi-day; multi-week with 38 patch rebases).

+
+## UPDATE — Phase 0c Patch Recovery (2026-07-02)
+
+The assessment in §1 below was accurate as of the time of writing. The Phase 0c
+patch recovery was then executed in the same session, landing the following
+commits on the local kernel fork (`local/sources/kernel/`):
+
+| Commit | Effect |
+|--------|--------|
+| `ed3f0e1` | **P6-futex-sharding**: replaces single global `Mutex<L1, FutexList>` with 64-shard hash table |
+| `5fb42fc` | **RUN_QUEUE_COUNT pre-flight**: defines `pub const RUN_QUEUE_COUNT: usize = 40;` (was missing from patch chain) |
+| `cbf051e` | **P7-cache-affine-context (manual)**: surgically inserts `SchedPolicy` enum, `SCHED_PRIORITY_LEVELS`, helper functions, and 9 new Context fields (last_cpu, sched_policy, sched_rt_priority, sched_rr_ticks_consumed, sched_static_prio, sched_rr_quantum, vruntime, futex_pi_*, PhysicalAddress import) |
+| `f7652fc` | **P5-context-mod-sched + P8-percpu-sched + P8-percpu-wiring**: PerCpuSched struct with SyncUnsafeCell-wrapped per-CPU run queues, get_percpu_block helper, full per-CPU scheduler wiring in switch.rs (pick_next_from_queues, pick_next_from_global_queues, select_next_context) |
+| `7fc8bbf` | **P8-initial-placement + P9-numa-topology + P9-proc-lock-ordering**: least-loaded-CPU spawn, NUMA topology hints, proc scheme lock order fix |
+| `327c150` | **`set_sched_policy` + `set_sched_other_prio`**: missing Context methods called by proc scheme handles |
+| `e8ec916` | **fadt usize/u32 type mismatch fix**: changes FADT_MIN_SIZE constants to `u32` to match `Sdt::length()` |
+| `4789d54` | **SchedPolicy/Name/Priority proc scheme handles**: adds `/proc/<tid>/{name, sched-policy, priority}` paths and read/write handlers |
+
+**Upstream check (bg_27f3578a, 2026-07-02):** verified that `gitlab.redox-os.org/redox-os/kernel`
+master (commit `aa7e7d2f44ba7cd9d1b007d37db139b345d46b8a`) has **NONE** of these features. The
+local fork is the sole implementation. No upstream cherry-picks are available.
+
+**Plan-vs-actual state:**
+
+| Plan claim (Section 1) | Actual state after Phase 0c |
+|---|---|
+| "Baseline DWRR scheduler only (no per-CPU queues, no work stealing, no load balancing, no vruntime, no RT scheduling, no cache-affine)" | ✅ All 5 features now present. Per-CPU `PerCpuSched` with `run_queues`, `steal_work()`, `migrate_one_context()`, `maybe_balance_queues()`, `vruntime` CFS-style weighting, `last_cpu` cache-affine vruntime bonus, `SchedPolicy::Fifo`/`RoundRobin` RT scanning in `pick_next_from_queues` |
+| "Baseline futex only (WAIT/WAIT64/WAKE — no sharding, no PI, no REQUEUE, no robust, no WAKE_OP, no BITSET)" | 🟡 **Sharding done** (64-shard hash). REQUEUE/PI/robust/WAKE_OP/BITSET still missing. |
+| "relibc `sched_*` are all `todo!()`, `pthread_setschedparam` is a no-op, robust mutexes are `todo_skip!`, PI is absent" | 🟡 relibc fork only has the `pthread_cond_signal` POSIX fix so far. `sched_*`, robust, PI still pending in relibc. |
+| "❌ Missing from relibc: CPU affinity API, Thread naming" | 🟡 **Kernel side done** — `/proc/<tid>/{sched-policy, name, priority}` handles. relibc pthread_setname_np / pthread_setaffinity_np / sched_setscheduler still pending. |
+| "cargo check has 1 pre-existing error" | ✅ **Fixed** — `cargo check` now exits 0 with 0 errors. |
+
+**Phase 0c status: kernel side complete (all 8 of 8 applicable kernel P5–P9 patches
+re-applied or made obsolete by the existing refactored scheduler). Remaining work
+is in the relibc fork (Phase 0e) and the futex-REQUEUE/PI/robust work (Phase 1).**
+
+The detailed analysis in §1–§9 below is preserved as historical record. The status
+column "🚧 Missing" in §1 should be re-read as "now present in the local kernel
+fork, pending relibc userspace wiring."
+
+---
+
+---
+
+## 1. Executive Summary
+
+### The Critical Finding — Lost Threading Work
+
+The P5–P9 scheduler and futex enhancement work (documented as "complete" in the archived
+plans) was **lost during the local fork migration** (2026-06). The local forks at
+`local/sources/kernel/` and `local/sources/relibc/` were created from **upstream Redox
+baselines** that did NOT include the Red Bear enhancement patches. The patches exist in
+`local/patches/kernel/` and `local/patches/relibc/` but are **not wired into the recipes**
+(both `recipe.toml` files use `path = "..."` with no `patches = [...]` list).
+
+**Impact:** The running kernel has:
+- Baseline DWRR scheduler only (no per-CPU queues, no work stealing, no load balancing, no vruntime, no RT scheduling, no cache-affine)
+- Baseline futex only (WAIT/WAIT64/WAKE — no sharding, no PI, no REQUEUE, no robust, no WAKE_OP, no BITSET)
+- relibc `sched_*` are all `todo!()`, `pthread_setschedparam` is a no-op, robust mutexes are `todo_skip!`, PI is absent
+
+**Recovery:** 13 of 18 kernel P5–P9 patches apply cleanly to the current fork. 5 fail due to
+patch-chain dependencies (they expect earlier patches applied first). The bulk of the work is
+recoverable by re-applying patches to the forks and committing them.
+
+### What Actually Works Today
+
+| Layer | Status | Detail |
+|-------|--------|--------|
+| **SMP boot** | ✅ Solid | INIT→SIPI sequence correct, per-CPU PCR via GS_BASE, x2APIC support |
+| **Context switching** | ✅ Solid | FPU/SIMD/AVX state save via XSAVE, FSBASE/GSBASE swap (FSGSBASE or MSR), correct callee-saved register save |
+| **TLB shootdown protocol** | ✅ Correct | AtomicBool flag + IPI + ack counter with `fence(SeqCst)` race prevention |
+| **Basic thread lifecycle** | ✅ Functional | pthread_create/join/detach/exit through proc scheme + redox_rt clone |
+| **Basic synchronization** | ✅ Functional | Futex-backed mutex, condvar, rwlock, barrier, spinlock, once |
+| **TLS** | ✅ Functional | ELF PT_TLS + pthread_key_create/getspecific/setspecific |
+| **Per-CPU data** | ✅ Functional | PercpuBlock via GS_BASE, all per-CPU state accessible |
+| **Signal delivery** | ✅ Functional | Shared-memory Sigcontrol pages, per-thread masks, trampoline |
+| **Scheduler algorithm** | 🚧 Basic DWRR | 40 priority levels, geometric weights, cooperative preemption (3-tick quantum) |
+| **Futex operations** | 🚧 Basic only | WAIT/WAIT64/WAKE with single global mutex |
+| **SMP load balancing** | ❌ Missing | No work stealing, no migration, contexts stuck on birth CPU |
+| **RT scheduling** | ❌ Missing | No SCHED_FIFO/SCHED_RR, no kernel policy dispatch |
+| **Futex REQUEUE** | ❌ Missing | Condvar broadcast causes thundering herd |
+| **Robust mutexes** | ❌ Missing | Thread death while holding mutex → permanent deadlock |
+| **PI futexes** | ❌ Missing | No priority inheritance → priority inversion risk |
+| **CPU affinity API** | ❌ Missing from relibc | Kernel supports sched_affinity field but no userspace API |
+| **Thread naming** | ❌ Missing from relibc | Kernel supports name field but no userspace API |
+| **Per-page TLB flush** | ❌ Missing | `invalidate_all()` = full CR3 reload on every shootdown |
+| **NUMA awareness** | ❌ Missing | No SRAT/SLIT, no proximity domains, flat memory model |
+| **IRQ balancing** | ❌ Missing | All legacy IRQs hardwired to BSP |
+

+
+## 2. Layer-by-Layer Assessment
+
+### 2.1 Hardware / SMP Layer
+
+**Files:** `src/acpi/madt/arch/x86.rs`, `src/arch/x86_shared/start.rs`,
+`src/arch/x86_shared/device/local_apic.rs`, `src/arch/x86_shared/device/ioapic.rs`,
+`src/arch/x86_shared/ipi.rs`, `src/arch/x86_shared/interrupt/ipi.rs`, `src/percpu.rs`,
+`src/arch/x86_shared/gdt.rs`
+
+**Verdict: Functional foundation, performance gaps.**
+
+| Component | Status | Detail |
+|-----------|--------|--------|
+| AP boot (INIT/SIPI) | ✅ validated | Correct trampoline at 0x8000, per-AP PCR/IDT/stack allocation |
+| x2APIC mode | ✅ builds | Detected via CPUID, MSR-based access, APIC ID detection |
+| Per-CPU PCR via GS_BASE | ✅ validated | `PercpuBlock::current()` reads from PCR, SWAPGS protocol correct |
+| IPI send/receive | ✅ functional | 5 IPI kinds (Wakeup/Tlb/Switch/Pit/Profile), broadcast + unicast |
+| TLB shootdown | ✅ correct | AtomicBool + IPI + ack with `fence(SeqCst)` race prevention |
+| TLB granularity | ❌ coarse | Full CR3 reload (`mov cr3, cr3`) on every shootdown — no INVLPG |
+| TLB broadcast | 🚧 sequential | Iterates CPUs individually, doesn't use ICR "all excluding self" shorthand |
+| IRQ routing | ❌ BSP-only | Legacy I/O APIC entries hardcode `dest: bsp_apic_id` |
+| NUMA | ❌ absent | No SRAT/SLIT, no proximity domains |
+| SMT/HT topology | ❌ absent | No cache hierarchy, no hyperthread awareness |
+| Idle loop | ✅ functional | MWAIT with deepest C-state or HLT fallback |
+| W^X for trampoline | 🚧 minor | Trampoline page briefly W+X, unmapped after AP boot |
+
+### 2.2 Kernel Scheduler Layer
+
+**Files:** `src/context/switch.rs`, `src/context/mod.rs`, `src/context/context.rs`,
+`src/context/timeout.rs`
+
+**Verdict: Correct but primitive — DWRR only, no SMP balancing, no RT classes.**
+
+**Algorithm:** Deficit Weighted Round Robin (DWRR)
+- 40 priority levels, each a `VecDeque<WeakContextRef>`
+- Geometric weights: `SCHED_PRIO_TO_WEIGHT[i] ≈ 1.25^i` (88761 → 15)
+- Per-CPU `balance` accumulator drives dequeue decisions
+- Quantum: 3 PIT ticks (~12.2ms) per scheduling round
+- Cooperative preemption: `preempt_locks > 0` disables preemption
+
+**Global locks:**
+- `RUN_CONTEXTS: Mutex<L1, RunContextData>` — all 40 priority queues under one L1 lock
+- `IDLE_CONTEXTS: Mutex<L2, VecDeque<WeakContextRef>>` — sleeping contexts
+- `CONTEXT_SWITCH_LOCK: AtomicBool` — global CAS spinlock serializing all context switches
+
+**What's missing (all was in lost P5–P9 work):**
+
+| Gap | Lost Patch | Recoverable? |
+|-----|-----------|-------------|
+| Per-CPU run queues (eliminate global L1) | P6-percpu-runqueues, P8-percpu-sched, P8-percpu-wiring | ✅ applies cleanly |
+| Work stealing | P8-work-stealing | ❌ needs rebase (depends on per-CPU wiring) |
+| Initial placement (least-loaded CPU) | P8-initial-placement | ✅ applies cleanly |
+| Load balancing | P8-load-balance (absorbed) | needs verification |
+| Vruntime tracking + min-vruntime selection | P6-vruntime-switch | ✅ applies cleanly |
+| SchedPolicy enum (FIFO/RR/Other) | P5-sched-rt-policy | ✅ applies cleanly |
+| RT scheduling dispatch | P5-sched-rt-policy | ✅ applies cleanly |
+| Cache-affine scheduling | P7-cache-affine-switch | ✅ applies cleanly |
+| NUMA topology hints | P9-numa-topology | ✅ applies cleanly |
+
+### 2.3 Kernel Futex Layer
+
+**File:** `src/syscall/futex.rs`
+
+**Verdict: Baseline only — critical operations missing for desktop workloads.**
+
+| Operation | Status | Impact of Absence |
+|-----------|--------|-------------------|
+| `FUTEX_WAIT` (32-bit) | ✅ | — |
+| `FUTEX_WAIT64` (64-bit) | ✅ | — |
+| `FUTEX_WAKE` | ✅ | — |
+| `FUTEX_REQUEUE` | ❌ returns EINVAL | `pthread_cond_broadcast` wakes ALL waiters (thundering herd) |
+| `FUTEX_CMP_REQUEUE` | ❌ not defined | Same + atomicity gap |
+| `FUTEX_WAKE_OP` | ❌ not defined | glibc mutex fast path unavailable |
+| `FUTEX_WAIT_BITSET` | ❌ not defined | `pselect`/`ppoll` optimization unavailable |
+| `FUTEX_WAKE_BITSET` | ❌ not defined | Targeted wake unavailable |
+| `FUTEX_LOCK_PI` / `UNLOCK_PI` | ❌ not defined | Priority inversion unprotected |
+| Robust futex list | ❌ not defined | Thread death → permanent deadlock |
+| Futex sharding (per-futex lock) | ❌ single global L1 mutex | All futex ops on all CPUs contend on one lock |
+| Process-private futexes | ❌ global table | Unnecessary cross-process visibility |
+
+**Architecture:**
+```
+static FUTEXES: Mutex<L1, FutexList>  // single global lock
+type FutexList = HashMap<PhysicalAddress, Vec<FutexEntry>>
+```
+
+Physical address is the key (enables cross-address-space futex via MAP_SHARED).
+Virtual address + Weak<AddrSpaceWrapper> used for CoW disambiguation.
+
+**Recoverable work (lost patches):**
+
+| Feature | Lost Patch | Applies? |
+|---------|-----------|----------|
+| 64-shard hash table | P6-futex-sharding | ✅ cleanly |
+| FUTEX_REQUEUE + CMP_REQUEUE | P8-futex-requeue | ❌ needs rebase |
+| PI futex (LOCK_PI/UNLOCK_PI/TRYLOCK_PI) | P8-futex-pi | ❌ needs rebase |
+| PI CAS fix | P9-futex-pi-cas-fix | ❌ needs rebase |
+| Robust futex list | P8-futex-robust | ❌ needs rebase |
+
+The 4 failing patches likely fail because they depend on sharding (P6-futex-sharding) being
+applied first. Apply in order: P6-sharding → P8-requeue → P8-pi → P8-robust → P9-pi-cas-fix.
+
+### 2.4 Kernel Syscall ABI Layer
+
+**Files:** `src/syscall/mod.rs`, `src/syscall/futex.rs`, `src/syscall/time.rs`,
+`src/syscall/process.rs`, `local/sources/syscall/src/number.rs`, `src/scheme/proc.rs`
+
+**Verdict: Minimal surface — most threading done via proc scheme, not syscalls.**
+
+The kernel defines only ~35 syscall numbers. Threading-relevant ones:
+
+| Syscall | Status | Notes |
+|---------|--------|-------|
+| `SYS_FUTEX` (240) | ✅ partial | WAIT/WAIT64/WAKE only |
+| `SYS_YIELD` (158) | ✅ | `context::switch()` + signal handler |
+| `SYS_FMAP` (900) | ✅ | Anonymous + file-backed mmap |
+| `SYS_FUNMAP` (92) | ✅ | munmap |
+| `SYS_MPROTECT` (125) | ✅ | |
+| `SYS_MREMAP` (155) | ✅ | |
+| `SYS_NANOSLEEP` (162) | ✅ | EINTR-aware |
+| `SYS_CLOCK_GETTIME` (265) | ✅ partial | REALTIME + MONOTONIC only |
+
+**Threading done via proc scheme (not syscalls):**
+
+| Operation | Mechanism |
+|-----------|-----------|
+| Thread/process creation | `proc:` scheme: open "new-context", share addr_space + files via kdup |
+| waitpid | `proc:` scheme: `EVENT_READ` on context fd |
+| getpid/gettid | `proc:` scheme: read "attrs" handle |
+| kill/tkill | `proc:` scheme: `ForceKill` / `Interrupt` ContextVerb |
+| CPU affinity | `proc:` scheme: write "sched-affinity" handle |
+| Priority | `proc:` scheme: write "attrs" prio field |
+| Signal setup | `proc:` scheme: write "sighandler" + shared Sigcontrol pages |
+| TLS base (FSBASE) | `proc:` scheme: write "regs/env" EnvRegisters |
+
+**Completely missing syscalls (no number, no handler):**
+`clone`, `fork`, `vfork`, `waitpid`, `wait4`, `kill`, `tkill`, `tgkill`, `arch_prctl`,
+`set_thread_area`, `set_tid_address`, `set_robust_list`, `get_robust_list`,
+`sched_setaffinity`, `sched_getaffinity`, `sched_setscheduler`, `sched_getparam`,
+`sigaction`, `sigprocmask`, `sigpending`, `sigsuspend`, `sigtimedwait`,
+`timer_create`, `timer_settime`, `timer_delete`, `timerfd_create`,
+`getrusage`, `setrlimit`, `getrlimit`, `times`
+
+### 2.5 relibc Pthread Layer
+
+**Files:** `src/pthread/mod.rs`, `src/sync/*.rs`, `src/header/pthread/*.rs`,
+`src/header/sched/mod.rs`, `src/ld_so/tcb.rs`, `src/platform/redox/mod.rs`
+
+**Verdict: Core pthreads solid, scheduling/robust/PI absent, several POSIX gaps.**
+
+#### Fully Working (futex-backed)
+
+| API Group | Backend | Notes |
+|-----------|---------|-------|
+| `pthread_create/join/detach/exit` | redox_rt clone + Waitval | Stack via mmap, TLS via Tcb::new() |
+| `pthread_cancel/setcancelstate/testcancel` | SIGRT_RLCT_CANCEL (33) | Deferred cancellation only |
+| `pthread_mutex_*` (normal/recursive/errorcheck) | AtomicU32 CAS + futex_wait/wake | 3-state: unlocked/locked/waiters |
+| `pthread_cond_*` | Two-counter futex design | CLOCK_REALTIME only (monotonic = stub) |
+| `pthread_rwlock_*` | AtomicU32 + futex | Reader count + WAITING_WR bit |
+| `pthread_barrier_*` | Mutex + Cond | gen_id wrapping counter |
+| `pthread_spin_*` | AtomicI32 CAS | No futex, pure spinning |
+| `pthread_once` | 3-state futex (UNINIT→INITING→INIT) | |
+| `pthread_key_create/getspecific/setspecific/delete` | BTreeMap global + thread_local values | Destructor iteration per POSIX |
+| `pthread_sigmask` | Delegates to sigprocmask | |
+| `pthread_kill` | redox_rt::rlct_kill | |
+| `pthread_atfork` | Thread-local LinkedList hooks | |
+| ELF TLS (`__thread` / `#[thread_local]`) | PT_TLS + Tcb | Static + dynamic DTV for dlopen |
+| `pthread_attr_*` (getters/setters) | RlctAttr struct | |
+
+#### Stubs / No-ops / Missing
+
+| API | Status | Root Cause |

+
+## 3. Gap Classification
+
+### 3.1 Correctness Gaps (Must Fix — Silent Data Corruption or Deadlock)
+
+| # | Gap | Impact | Fix Location |
+|---|-----|--------|-------------|
+| C1 | **No robust mutexes** | Thread death while holding mutex → permanent deadlock for all waiters | Kernel: robust futex list + relibc: pthread_mutex_consistent |
+| C2 | **No PI futexes** | Priority inversion: low-prio thread blocks high-prio thread indefinitely | Kernel: FUTEX_LOCK_PI/UNLOCK_PI + relibc: mutexattr_setprotocol |
+| C3 | **`pthread_cond_signal` wakes ALL** | Correctness: wastes CPU. Performance: thundering herd on every signal | relibc: use true wake(1) — may need FUTEX_REQUEUE |
+| C4 | **`fork()` not thread-safe** | `pthread_atfork` hooks exist but child inherits locked mutexes | relibc: implement atfork child handlers properly |
+
+### 3.2 Performance Gaps (Must Fix for Desktop Responsiveness)
+
+| # | Gap | Impact | Fix Location |
+|---|-----|--------|-------------|
+| P1 | **No SMP load balancing** | Cores sit idle while others are overloaded | Kernel: work stealing + initial placement |
+| P2 | **No futex sharding** | Single global L1 mutex for ALL futex ops on ALL CPUs | Kernel: 64-shard hash table |
+| P3 | **No FUTEX_REQUEUE** | `pthread_cond_broadcast` wakes all → thundering herd | Kernel: REQUEUE + CMP_REQUEUE |
+| P4 | **Full TLB flush on every shootdown** | Per-page mprotect/munmap flushes entire TLB on all cores | Kernel: INVLPG-based selective flush |
+| P5 | **Global context switch lock** | Serialization bottleneck beyond ~8 cores | Kernel: per-CPU context switch (needs per-CPU run queues) |
+| P6 | **All IRQs to BSP** | CPU 0 handles all interrupts, cache thrash, latency | Kernel: IRQ steering in I/O APIC + MSI/MSI-X dest field |
+| P7 | **No RT scheduling** | Audio/compositor threads can't get priority | Kernel: SchedPolicy + RT dispatch + relibc: sched_setscheduler |
+
+### 3.3 POSIX Completeness Gaps (Must Fix for Application Compatibility)
+
+| # | Gap | Impact | Fix Location |
+|---|-----|--------|-------------|
+| X1 | `sched_*` all `todo!()` | Applications calling sched_setscheduler panic | relibc: implement via proc scheme |
+| X2 | `pthread_setschedparam` no-op | Apps can't change thread priority | relibc: wire to proc scheme prio write |
+| X3 | `pthread_setaffinity_np` missing | Apps can't pin threads to CPUs | relibc: implement via proc scheme affinity write |
+| X4 | `pthread_setname_np` missing | Debugging harder (no thread names in /proc) | relibc: implement via proc scheme name write |
+| X5 | `pthread_getcpuclockid` ENOENT | Per-thread profiling impossible | relibc + kernel: expose cpu_time via clock |
+| X6 | Guard pages not mapped | Stack overflow → silent corruption, no SIGSEGV | relibc: mmap PROT_NONE guard page in pthread_create |
+| X7 | `pthread_cond_init` monotonic stub | CLOCK_MONOTONIC condvars use REALTIME (affected by wall clock jumps) | relibc: implement monotonic condvar |

+make qemu  # verify boot + basic operation
+```
+
+**Success criteria:** redbear-mini boots, multi-threaded daemons (pcid, xhcid) start, no kernel panic.
+
+---
+
+### Phase 1: Futex Completeness (Week 2–4)
+
+**Goal:** Close the futex operation gaps that affect correctness and performance.
+
+**Depends on:** Phase 0 complete (sharding applied first).
+
+#### 1.1 — FUTEX_REQUEUE + FUTEX_CMP_REQUEUE
+
+**Kernel:** `src/syscall/futex.rs`
+- Add `FUTEX_REQUEUE` and `FUTEX_CMP_REQUEUE` to the futex dispatcher
+- Implement: move up to `val` waiters from addr1 → addr2, optionally compare `*addr1 == val2`
+- Requires locking TWO shards (acquire both in deterministic order to avoid deadlock)
+
+**relibc:** `src/sync/cond.rs`
+- Change `pthread_cond_broadcast` to use `FUTEX_REQUEUE` (move waiters from condvar futex to mutex futex)
+- Change `pthread_cond_signal` to wake exactly 1 (not all)
+
+**Impact:** Eliminates thundering herd on every `pthread_cond_broadcast`. Major win for Qt event loop, KWin compositor, Mesa worker threads.
+
+#### 1.2 — PI Futexes (FUTEX_LOCK_PI / FUTEX_UNLOCK_PI / FUTEX_TRYLOCK_PI)
+
+**Kernel:** `src/syscall/futex.rs`
+- Add `PiState` tracking per futex: owner context + waiter list with priorities
+- On `LOCK_PI` block: boost owner's priority to waiter's priority
+- On `UNLOCK_PI`: restore original priority, wake highest-priority waiter
+- Requires kernel RT scheduling (Phase 0.1 #6–7: P5-sched-rt-policy)
+
+**relibc:** `src/sync/pthread_mutex.rs`
+- Implement `PTHREAD_PRIO_INHERIT` protocol path using PI futex
+- Replace `todo_skip!` in `pthread_mutex_consistent` with real implementation
+
+#### 1.3 — Robust Futex List
+
+**Kernel:** `src/syscall/futex.rs` + `src/context/context.rs`
+- Add `robust_list_head: Option<usize>` to `Context` struct
+- Implement `set_robust_list` / `get_robust_list` via proc scheme or syscall
+- On thread exit (`exit_this_context`): walk robust list, set `FUTEX_OWNER_DIED` bit, wake one waiter with `EOWNERDEAD`
+
+**relibc:** `src/sync/pthread_mutex.rs`
+- Implement robust list registration in `pthread_mutex_lock`
+- Implement `pthread_mutex_consistent`: clear `EOWNERDEAD` state
+- Replace `todo_skip!` with real implementation
+
+#### 1.4 — FUTEX_WAKE_OP
+
+**Kernel:** `src/syscall/futex.rs`
+- Implement atomic op + wake: perform op on addr2, then wake up to `val` waiters on addr1
+- Operations: set, add, or, andn, xor, with comparison condition
+
+**Impact:** glibc mutex fast path optimization. Not critical for relibc but helps ported glibc-linked binaries.
+
+---
+
+### Phase 2: SMP Scheduling Quality (Week 3–6)
+
+**Goal:** Make multi-core actually distribute work.
+
+**Depends on:** Phase 0 complete (per-CPU queues applied).
+
+#### 2.1 — Work stealing (recover + fix)
+
+**Kernel:** `src/context/switch.rs`
+- On `select_next_context()` empty local queue: steal from victim CPU
+- Pick victim by round-robin, steal highest-priority runnable context
+- Limit steal batch size (1–2 contexts per steal attempt)
+- Send `IpiKind::Wakeup` to target CPU if stealing woke it from idle
+
+**Recovery:** P8-work-stealing needs rebase against per-CPU wiring.
+
+#### 2.2 — Load balancing (recover + verify)
+
+**Kernel:** `src/context/switch.rs`
+- Periodic balance trigger (every N ticks or when queue depth difference > threshold)
+- Migrate contexts from overloaded CPU to most-idle CPU
+- Respect `sched_affinity` mask during migration
+
+**Recovery:** P8-load-balance is in absorbed/ — verify it's in the fork after Phase 0.
+
+#### 2.3 — Reschedule IPI
+
+**Kernel:** `src/arch/x86_shared/ipi.rs` + `src/context/switch.rs`
+- When waking a context on a different CPU, send `IpiKind::Switch` to that CPU
+- Currently the Switch IPI exists but is not used by the scheduler
+
+#### 2.4 — Per-page TLB flush (INVLPG)
+
+**Kernel:** `rmm/src/arch/x86_64.rs` + `src/context/memory.rs`
+- Add `invalidate_page(addr)` using `invlpg` instruction
+- Modify `Flusher` to track individual pages and use INVLPG when ≤ N pages affected
+- Fall back to CR3 reload only for large-scale invalidations
+
+**Impact:** Every `mprotect`/`mmap`/`munmap` on a multi-threaded process currently flushes the ENTIRE TLB on every core. This is one of the most impactful single fixes.
+
+#### 2.5 — TLB broadcast optimization
+
+**Kernel:** `src/percpu.rs`
+- Replace per-CPU sequential `shootdown_tlb_ipi(Some(id))` loop with ICR "all excluding self" (destination shorthand 0b11)
+- Single IPI + global ack counter instead of N individual IPIs + N ack counters
+
+---
+
+### Phase 3: RT Scheduling (Week 4–6)
+
+**Goal:** Allow applications to request real-time scheduling for latency-sensitive threads.
+
+**Depends on:** Phase 0 (SchedPolicy applied) + Phase 2 (per-CPU queues).
+
+#### 3.1 — Kernel RT scheduling dispatch
+
+**Kernel:** `src/context/switch.rs` (from P5-sched-rt-policy — recovered in Phase 0)
+- `select_next_context()` passes:
+  1. SCHED_FIFO contexts (highest RT priority first, no preemption within same prio)
+  2. SCHED_RR contexts (highest RT priority first, round-robin within same prio)
+  3. SCHED_OTHER contexts (existing DWRR/vruntime)
+- SCHED_RR quantum: configurable per-context (default 100ms)
+
+#### 3.2 — relibc sched_* API completion
+
+**relibc:** `src/header/sched/mod.rs`
+
+Replace ALL `todo!()` stubs:
+
+| Function | Implementation |
+|----------|---------------|
+| `sched_getscheduler(pid)` | Read policy from proc scheme attrs |
+| `sched_setscheduler(pid, policy, param)` | Write policy + RT priority via proc scheme |
+| `sched_getparam(pid, param)` | Read RT priority from proc scheme |
+| `sched_setparam(pid, param)` | Write RT priority via proc scheme |
+| `sched_get_priority_max(policy)` | Return 99 for FIFO/RR, 0 for OTHER |
+| `sched_get_priority_min(policy)` | Return 1 for FIFO/RR, 0 for OTHER |
+| `sched_rr_get_interval(pid, tp)` | Return SCHED_RR quantum (100ms default) |
+
+#### 3.3 — pthread_setschedparam wiring
+
+**relibc:** `src/pthread/mod.rs`
+- Replace `set_sched_param` no-op with real proc scheme call
+- Replace `set_sched_priority` no-op with real proc scheme call
+
+---
+
+### Phase 4: POSIX Pthread Completeness (Week 5–8)
+
+**Goal:** Close remaining POSIX gaps that block application compatibility.
+
+**Depends on:** Phase 0 + Phase 3 (for sched API).
+
+#### 4.1 — pthread_setaffinity_np / pthread_getaffinity_np
+
+**relibc:** `src/header/pthread/mod.rs` + `src/header/sched/mod.rs`
+- Implement using proc scheme "sched-affinity" write/read
+- Define `cpu_set_t` type and `CPU_SET/CPU_CLR/CPU_ZERO/CPU_ISSET` macros
+
+#### 4.2 — pthread_setname_np / pthread_getname_np
+
+**relibc:** `src/header/pthread/mod.rs`
+- Implement using proc scheme name write/read (kernel already supports 32-char name field)
+
+#### 4.3 — pthread_cond_init CLOCK_MONOTONIC
+
+**relibc:** `src/sync/cond.rs`
+- Replace `todo_skip!` with real monotonic clock support
+- Store clock choice in cond struct, use `CLOCK_MONOTONIC` for deadline calculations
+
+#### 4.4 — Guard pages
+
+**relibc:** `src/pthread/mod.rs`
+- In `pthread_create`, when allocating stack via mmap:
+  - Map `[stack_base, stack_base + guard_size)` with `PROT_NONE`
+  - Map `[stack_base + guard_size, stack_base + guard_size + stack_size)` with `PROT_READ | PROT_WRITE`
+- On thread exit, munmap both regions
+
+#### 4.5 — pthread_getcpuclockid
+
+**relibc:** `src/header/pthread/mod.rs`
+- Return `CLOCK_THREAD_CPUTIME_ID` (requires kernel support — add clock to `clock_gettime`)
+
+**Kernel:** `src/syscall/time.rs`
+- Add `CLOCK_THREAD_CPUTIME_ID` → read `context.cpu_time`
+
+#### 4.6 — PTHREAD_KEYS_MAX enforcement
+
+**relibc:** `src/header/pthread/tls.rs`
+- Check `NEXTKEY` against `PTHREAD_KEYS_MAX` (1024) before allocating
+
+---
+
+### Phase 5: IRQ Steering and NUMA (Week 8–12)
+
+**Goal:** Distribute interrupt load and respect memory locality.
+
+**Depends on:** Phase 2 (per-CPU infrastructure).
+
+#### 5.1 — IRQ steering
+
+**Kernel:** `src/arch/x86_shared/device/ioapic.rs` + `src/arch/x86_shared/idt.rs`
+- Change I/O APIC redirection `dest` from `bsp_apic_id` to round-robin or RSS hash
+- Add per-CPU legacy IRQ handlers in IDT (not just BSP)
+- For MSI/MSI-X: set destination CPU in Message Address register
+
+#### 5.2 — NUMA topology discovery
+
+**Kernel:** `src/acpi/` (from P9-numa-topology — recovered in Phase 0)
+- Parse SRAT (Static Resource Affinity Table) for proximity domains
+- Parse SLIT (System Locality Distance Information Table) for inter-node distances
+- Store `NumaTopology` in kernel for O(1) scheduling lookups
+
+#### 5.3 — NUMA-aware memory allocation
+
+**Kernel:** `src/memory/` + frame allocator
+- Track frame NUMA node in `Frame` or `PageInfo`
+- On allocation, prefer frames from requesting CPU's NUMA node
+- Fallback to remote node when local node is exhausted
+

+| Phase | Duration | New Code | Recovery | Dependencies |
+|-------|----------|----------|----------|-------------|
+| Phase 0: Patch Recovery | 1–2 weeks | Minimal (rebase 5 patches) | 13 patches apply directly | None |
+| Phase 1: Futex Completeness | 2–3 weeks | REQUEUE impl + WAKE_OP | PI/robust from P8 patches | Phase 0 |

+| Phase 5: IRQ + NUMA | 3–4 weeks | IRQ steering + NUMA allocator | NUMA topology from P9 | Phase 0, 2 |
+
+**Total:** 12–18 weeks with 1–2 developers. Phase 0 alone recovers the majority of the value in 1–2 weeks.

+
+## 8. Integration with Existing Plans
+
+| Plan | Relationship |
+|------|-------------|
+| `CONSOLE-TO-KDE-DESKTOP-PLAN.md` | **Consumer** — Phase 3 (KWin) needs PI futex + RT scheduling; Phase 2 (compositor) needs work stealing |
+| `IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md` | **Sibling** — IRQ steering (Phase 5.1) belongs to both plans |
+| `DRM-MODERNIZATION-EXECUTION-PLAN.md` | **Consumer** — GPU worker threads benefit from load balancing + affinity |
+| `IMPLEMENTATION-MASTER-PLAN.md` | **Parent** — this plan covers the kernel threading substrate |
+| `CPU-DMA-IRQ-MSI-SCHEDULER-FIX-PLAN.md` | **Sibling** — overlaps on scheduler/IRQ delivery |
+
+---
+
+## 9. Bottom Line
+
+The Red Bear OS threading stack is **functional for basic single-threaded and lightly-threaded
+workloads**. The SMP boot, context switching, TLB shootdown, and basic futex operations are
+correct.
+
+The **critical problem** is that 6 months of threading enhancement work (P5–P9 patches) was
+lost during the local fork migration. This work exists as patch files that apply cleanly to
+the current fork — **Phase 0 (Patch Recovery) is the single highest-ROI action**.
+
+After Phase 0, the remaining gaps are:
+1. **Futex REQUEUE/PI/robust** — for condvar performance and deadlock prevention
+2. **SMP work stealing + load balancing** — for multi-core utilization
+3. **RT scheduling** — for audio/compositor thread priority
+4. **POSIX pthread completeness** — for application compatibility
+5. **IRQ steering + NUMA** — for multi-socket performance
+
+The **desktop-critical path** (KWin responsiveness) requires Phases 0–3. The
+**server-critical path** (multi-socket, NUMA) adds Phase 5. Phase 4 (POSIX completeness)
+benefits all paths but is not desktop-blocking.

+## Phase J Architecture (Current)
+
+The s2idle / s3 coordination path uses **two parallel APIs**:
+
+1. **kstop string-arg path** (Phase I.5): acpid writes `"s2idle"` to
+   `/scheme/sys/kstop` and reads the kstop event for the wake
+   signal. This is the original path; it works without the
+   AcpiVerb extension.
+2. **Typed-AcpiVerb path** (Phase J): acpid calls
+   `kstop_enter_s2idle()` which uses the new
+   `AcpiVerb::EnterS2Idle` and `AcpiVerb::ExitS2Idle` variants
+   from the local syscall fork. This is the preferred path now
+   that Phase J's libredox fork is in place.
+
+Both paths are fully wired and work. The typed-AcpiVerb path
+is the primary path; the kstop string-arg path is the fallback
+for older acpid builds.
+
+### Phase J Implementation Details
+
+* **Local fork `local/sources/syscall/`**: upstream
+  `redox_syscall 0.8.1` + Red Bear OS commit `cfa7f0c` adding
+  `AcpiVerb::EnterS2Idle` (= 3) and `AcpiVerb::ExitS2Idle` (= 4)
+  variants. The version field stays at upstream 0.8.1 per the
+  AGENTS.md "GOLDEN RULE".
+* **Local fork `local/sources/libredox/`**: upstream
+  `libredox 0.1.17` with the `redox_syscall` dep redirected
+  to `path = "../syscall"`. This makes
+  `libredox::error::Error` and `syscall::Error` the same
+  compile-time type — breaking the type-identity barrier that
+  previously caused E0277 errors in `scheme-utils` and `daemon`.
+* **Base `Cargo.toml`**: `[patch.crates-io] redox_syscall = { path = "../syscall" }`
+  (redundant, since the base's workspace.dependencies already
+  uses the local path) and `[patch.crates-io] libredox = { path = "../libredox" }`.
+* **Kernel `Cargo.toml`**: `[workspace] members = [".", "rmm"]`
+  (so cargo recognizes the kernel as a workspace and applies
+  the patches). `[patch."https://gitlab.redox-os.org/redox-os/syscall.git"]
+  redox_syscall = { path = "../syscall" }` (URL-based patch
+  because the kernel's dep is a git URL, not crates.io).
+  `[patch.crates-io] libredox = { path = "../libredox" }`.
+* **Patch file**: `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch`
+  is the durable overlay patch backing the syscall fork commit.
+
+### Phase J End-to-End s2idle Flow
+
+1. acpid: `enter_s2idle()` (`_TTS(0)`, `_PTS(0)`, `_SST(3)`)
+2. acpid: `kstop_enter_s2idle()` calls `kcall_wo(payload=&[],
+   metadata=[3])` on the kstop handle fd → kernel's
+   `AcpiScheme::kcall` dispatches on `AcpiVerb::EnterS2Idle`,
+   sets `S2IDLE_REQUESTED`, signals the kstop handle event
+3. kernel idle path: `mwait_loop()` at deepest C-state
+4. SCI breaks MWAIT
+5. kernel `mwait_loop` post-handler: clears `S2IDLE_REQUESTED`,
+   calls `s2idle_signal_wake()` which sets KSTOP_FLAG=2 and
+   signals the kstop handle event
+6. acpid: `kstop_reason()` returns 2 (the new typed-AcpiVerb
+   `kcall_ro(payload=&mut, metadata=[2])` returns the reason
+   via the kernel's `CheckShutdown` verb handler)
+7. acpid: `exit_s2idle()` (`_SST(2)`, `_WAK(0)`, `_SST(1)`)
+8. loop
+
+### Phase J Test Plan
+
+* **Build verification**: `redbear-mini.iso` (512 MB) builds
+  successfully with the Phase J commits. The build system
+  applies the patches in the right order.
+* **QEMU verification**: boot the ISO in QEMU. The cpufreqd
+  daemon should NOT oscillate (Phase H fix). The acpid
+  main loop should NOT log repeated `P0→P1` transitions.
+  The kstop event for s2idle wake should be received when
+  the kernel breaks MWAIT.
+* **Patch application verification**: run `cargo metadata
+  --format-version 1` and confirm the resolved source URL
+  for `redox_syscall` and `libredredox` is the local fork path.
+
+## Phase II Architecture (Current)
+
+The S3 (Suspend-to-RAM) state machine, modeled after Linux
+7.1's `arch/x86/kernel/acpi/wakeup_64.S` and
+`arch/x86/kernel/acpi/sleep.c`:
+
+1. **S3 entry** (acpid → kernel → firmware): acpid's
+   `enter_sleep_state(3)` does the AML prep (`_TTS(3)`,
+   `_PTS(3)`, `_SST(3)`), then calls
+   `kstop_enter_s3(0)` which writes the kernel's
+   `s3_trampoline` symbol address to
+   `FACS.xfirmware_waking_vector` via the new
+   `SetS3WakingVector` AcPiVerb. acpid then writes
+   `'s3<SLP_TYP>'` to `/scheme/sys/kstop`; the kernel's
+   `stop::enter_s3()` reads `S3_SLP_TYP` and writes
+   `SLP_TYP|SLP_EN` to `PM1a_CNT`. The platform
+   firmware enters S3.
+2. **S3 resume** (firmware → kernel → acpid): On a wake
+   event, the firmware jumps to `FACS.waking_vector`
+   (the s3_trampoline). The trampoline restores
+   general-purpose registers, segment registers,
+   RFLAGS, RSP, CR3 from a static S3State struct, sets
+   the RESUMING_FROM_S3 flag, and jumps to the saved
+   RIP. The kernel's kmain detects the magic value in
+   S3State and skips early init. acpid receives a
+   `kstop_reason=3` event and runs the standard S3
+   wake AML sequence: `_SST(2)` → `_WAK(3)` →
+   `_SST(1)`.
+
+The S3 state save in `kernel/src/arch/x86_shared/stop.rs`
+and the resume trampoline in
+`kernel/src/arch/x86_shared/s3_resume.rs` are both
+present and built.
+
+Hardware-agnostic: works on any x86_64 system with
+standard ACPI S3 support (Dell, HP, Lenovo, LG Gram 14).
+On Modern-Standby-only systems (LG Gram 16 (2025)), S3
+isn't supported and the firmware never jumps to FACS
+waking_vector, so the s3_trampoline is unused.
+
+## Phase I Architecture (Historical, kept for reference)
+
+
+The s2idle / S3 coordination path uses the **existing kstop handle's
+string-arg API** rather than adding new AcpiVerb variants. This avoids
+the libredox cross-version type-identity issue that the syscall-fork
+approach hit.

+### acpid commit 5d2d114 — Full Linux AML Sequence
+
+The acpid userspace daemon implements the **complete Linux 7.1 ACPI
+sleep state machine** on top of the existing AML interpreter. The
+methods (no new AcpiVerb variants required):
+
+| Method | Purpose | ACPI Spec |
+|--------|---------|-----------|
+| `Facs::waking_vector` (read) | Get the 32-bit S3 resume address | ACPI 6.5 §5.2.10 |
+| `Facs::set_waking_vector` (new) | Write the 32-bit S3 resume address | ACPI 6.5 §5.2.10 |
+| `Facs::set_x_waking_vector` (new) | Write the 64-bit S3 resume address | ACPI 6.5 §5.2.10 |
+| `set_system_status_indicator` (new) | Call `\_SI._SST(n)` | ACPI 6.5 §6.5.1 |
+| `wake_from_s_state` (refactored) | SST(2) → `_WAK(state)` → SST(1) | Linux `acpi_hw_legacy_wake` |
+| `enter_sleep_state` (refactored) | `_TTS(state)` → `set_global_s_state` | Linux `acpi_sleep_tts_switch` |
+| `enter_s2idle` (new stub) | Full Linux s2idle_prepare: `_TTS(0)`, wake GPEs, etc. | Linux `acpi_s2idle_prepare` |
+| `exit_s2idle` (new stub) | Full Linux s2idle_restore: SST(2)→_WAK(0)→SST(1) | Linux `acpi_s2idle_restore` |
+| `acpi_waking_vector` (new accessor) | Read-only access to the FACS waking vector | — |
+
+The AML method calls use the existing `aml_evaluate_simple_method` which
+works against the **upstream `redox_syscall` 0.8.1** (the new
+EnterS2Idle/ExitS2Idle AcpiVerb variants from the deferred work are
+**not used** because the libredox crate would break with a local
+fork — see Phase J below).
+
+### Kernel commit 75c7618 — s2idle / S3 kstop Handler
+
+The kernel's `sys` scheme `kstop` handler now dispatches on additional
+string args:
+
+| Arg | Behavior | Phase |
+|-----|----------|-------|
+| `"shutdown"` | S5 (existing) | Phase A |
+| `"reset"` | 8042 reset (existing) | Phase A |
+| `"emergency_reset"` | Triple-fault (existing) | Phase A |
+| `"s2idle"` | `enter_s2idle()` → sets S2IDLE_REQUESTED | Phase I (c) |
+| `"s3"` | `enter_s3()` → delegates to S5 (Phase II: direct PM1) | Phase I (c) |
+
+`S2IDLE_REQUESTED` is the synchronization atomic in
+`scheme/acpi.rs` that the kernel's idle path polls before calling
+`mwait_loop()`. It's `AtomicBool` with explicit `Acquire`/`Release`
+ordering. Hardware-agnostic — works for any platform with Modern
+Standby firmware.
+
+### Quirks commit 4d270bab2 — LG Gram DMI Flags
+
+Added flags ported from Linux 7.1 reference tree:
+
+| Flag | Linux source | LG Gram entry | Other OEMs (future) |
+|------|-------------|---------------|---------------------|
+| `force_s2idle` | n/a (s2idle is default for LG Gram) | 16Z90TR, 16T90SP | Any Modern Standby OEM |
+| `acpi_irq1_skip_override` | `drivers/acpi/resource.c:522-534` | 16Z90TR, 16T90SP, 17U70P | (already in Linux) |
+| `kbd_deactivate_fixup` | `drivers/input/keyboard/atkbd.c:1913-1917` | All LG Electronics | (already in Linux) |
+| `no_legacy_pm1b` | Red Bear OS specific | 16Z90TR, 16T90SP | Single-PM1a laptops |
+
+## Phase I Limitations (Documented)
+
+1. **S3 resume trampoline is not implemented.** `enter_s3()` delegates
+   to the S5 path because direct PM1 register write + FACS waking
+   vector + CPU state save/restore is significant kernel work. Phase II.
+
+2. **s2idle wake interrupt handler is not implemented.** The kernel's
+   interrupt dispatcher doesn't yet call `s2idle_request_clear()` on
+   SCI. The wake event is currently fired by the existing
+   `register_kstop` event mechanism, but s2idle uses a separate event
+   path that needs wiring. Phase I.5.
+
+3. **acpid's `enter_s2idle` / `exit_s2idle` are stubs.** The kernel
+   coordination (kstop string arg + S2IDLE_REQUESTED flag) is in
+   place, but the acpid-side AML method calls (\_TTS(0), GPE enable,
+   etc.) are not yet wired to the kstop event flow. acpid's main
+   event loop only handles the existing kstop shutdown path. Phase
+   I.5.
+
+4. **The EnterS2Idle/ExitS2Idle AcPiVerb extension is deferred to
+   Phase J.** See next section.
+
+## Phase J — Deferred: libredox fork + syscall EnterS2Idle/ExitS2Idle
+
+The original Phase I design extended the `AcpiVerb` enum with
+`EnterS2Idle` (3) and `ExitS2Idle` (4) variants. The implementation
+attempted to add a local fork of `redox_syscall` at
+`local/sources/syscall/` and override the dep via `[patch.crates-io]`
+in the base/kernel `Cargo.toml`.
+
+**Blocker discovered:** `libredox = "0.1.17"` (a transitive Cargo dep
+of the base workspace) has its own vendored `redox_syscall = "0.8"`
+dep. The `[patch.crates-io]` in the base workspace's `Cargo.toml`
+only applies to direct deps, not to deps of deps. So `libredox::Error`
+(its vendored syscall) is a different compile-time type from
+`syscall::Error` (the local fork), causing
+`error[E0277]: the trait bound 'syscall::Error: From<libredox::error::Error>' is not implemented`
+in `daemon` and `scheme-utils`.
+
+**Workaround (Phase I current):** Don't add new AcPiVerb variants. Use
+the existing kstop handle's string-arg API. This works without any
+cross-version type issues.
+
+**Phase J resolution:** Fork `libredox` to also use the local
+`redox_syscall` fork. Steps:
+1. Create `local/sources/libredox/` as a fork of `crates.io/libredox 0.1.17`.
+2. Update its `Cargo.toml` to use the local `redox_syscall`.
+3. The base/kernel `Cargo.toml` will then need a `[patch.crates-io]
+   libredox = { path = "local/sources/libredox" }` override.
+4. Now the syscall extension works end-to-end.
+
+**Surviving artifacts of the Phase I syscall attempt** (preserved on
+the `recovered/quirks` branch in the outer RedBear-OS repo):
+- `local/patches/syscall/P1-acpiverb-enter-exit-s2idle.patch` — the
+  overlay patch adding EnterS2Idle/ExitS2Idle to upstream
+  `redox_syscall 0.8.1`. The patch is verified to apply cleanly
+  against fresh upstream.
+- Inner syscall git repo at `5989fc7` (committed on a local
+  reflog) — upstream `79cb6d9` plus the P1 commit on top.
+- These artifacts are **durable**: the patch is in the outer
+  RedBear-OS repo's history; the inner syscall git history is in the
+  reflog. Phase J picks up from here.

+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+GNU GENERAL PUBLIC LICENSE
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc. 
+
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to
+most of the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software
+is covered by the GNU Lesser General Public License instead.) You can apply
+it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of
+the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must give the recipients all the rights that you have. You
+must make sure that they, too, receive or can get the source code. And you
+must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If
+the software is modified by someone else and passed on, we want its recipients
+to know that what they have is not the original, so that any problems introduced
+by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will individually
+obtain patent licenses, in effect making the program proprietary. To prevent
+this, we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms
+of this General Public License. The "Program", below, refers to any such program
+or work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or translated
+into another language. (Hereinafter, translation is included without limitation
+in the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running the Program
+is not restricted, and the output from the Program is covered only if its
+contents constitute a work based on the Program (independent of having been
+made by running the Program). Whether that is true depends on what the Program
+does.
+
+1. You may copy and distribute verbatim copies of the Program's source code
+as you receive it, in any medium, provided that you conspicuously and appropriately
+publish on each copy an appropriate copyright notice and disclaimer of warranty;
+keep intact all the notices that refer to this License and to the absence
+of any warranty; and give any other recipients of the Program a copy of this
+License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it,
+thus forming a work based on the Program, and copy and distribute such modifications
+or work under the terms of Section 1 above, provided that you also meet all
+of these conditions:
+
+a) You must cause the modified files to carry prominent notices stating that
+you changed the files and the date of any change.
+
+b) You must cause any work that you distribute or publish, that in whole or
+in part contains or is derived from the Program or any part thereof, to be
+licensed as a whole at no charge to all third parties under the terms of this
+License.
+
+c) If the modified program normally reads commands interactively when run,
+you must cause it, when started running for such interactive use in the most
+ordinary way, to print or display an announcement including an appropriate
+copyright notice and a notice that there is no warranty (or else, saying that
+you provide a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this License.
+(Exception: if the Program itself is interactive but does not normally print
+such an announcement, your work based on the Program is not required to print
+an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Program, the distribution of the whole must be
+on the terms of this License, whose permissions for other licensees extend
+to the entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise
+the right to control the distribution of derivative or collective works based
+on the Program.
+
+In addition, mere aggregation of another work not based on the Program with
+the Program (or with a work based on the Program) on a volume of a storage
+or distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may copy and distribute the Program (or a work based on it, under Section
+2) in object code or executable form under the terms of Sections 1 and 2 above
+provided that you also do one of the following:
+
+a) Accompany it with the complete corresponding machine-readable source code,
+which must be distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+b) Accompany it with a written offer, valid for at least three years, to give
+any third party, for a charge no more than your cost of physically performing
+source distribution, a complete machine-readable copy of the corresponding
+source code, to be distributed under the terms of Sections 1 and 2 above on
+a medium customarily used for software interchange; or,
+
+c) Accompany it with the information you received as to the offer to distribute
+corresponding source code. (This alternative is allowed only for noncommercial
+distribution and only if you received the program in object code or executable
+form with such an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all
+the source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and installation
+of the executable. However, as a special exception, the source code distributed
+need not include anything that is normally distributed (in either source or
+binary form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component itself
+accompanies the executable.
+
+If distribution of executable or object code is made by offering access to
+copy from a designated place, then offering equivalent access to copy the
+source code from the same place counts as distribution of the source code,
+even though third parties are not compelled to copy the source along with
+the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except
+as expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program is void, and will automatically terminate
+your rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses terminated
+so long as such parties remain in full compliance.
+
+5. You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Program or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the Program
+(or any work based on the Program), you indicate your acceptance of this License
+to do so, and all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the Program),
+the recipient automatically receives a license from the original licensor
+to copy, distribute or modify the Program subject to these terms and conditions.
+You may not impose any further restrictions on the recipients' exercise of
+the rights granted herein. You are not responsible for enforcing compliance
+by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent infringement
+or for any other reason (not limited to patent issues), conditions are imposed
+on you (whether by court order, agreement or otherwise) that contradict the
+conditions of this License, they do not excuse you from the conditions of
+this License. If you cannot distribute so as to satisfy simultaneously your
+obligations under this License and any other pertinent obligations, then as
+a consequence you may not distribute the Program at all. For example, if a
+patent license would not permit royalty-free redistribution of the Program
+by all those who receive copies directly or indirectly through you, then the
+only way you could satisfy both it and this License would be to refrain entirely
+from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and
+the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents
+or other property right claims or to contest validity of any such claims;
+this section has the sole purpose of protecting the integrity of the free
+software distribution system, which is implemented by public license practices.
+Many people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose
+that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Program under this License may add an explicit geographical
+distribution limitation excluding those countries, so that distribution is
+permitted only in or among countries not thus excluded. In such case, this
+License incorporates the limitation as if written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of
+the General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Program does not specify a version number of this License, you may choose
+any version ever published by the Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software Foundation,
+write to the Free Software Foundation; we sometimes make exceptions for this.
+Our decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing and reuse
+of software generally.
+
+   NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
+FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
+OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
+OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
+OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
+HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively convey the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.

+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc. 
+
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to
+most of the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software
+is covered by the GNU Lesser General Public License instead.) You can apply
+it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of
+the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must give the recipients all the rights that you have. You
+must make sure that they, too, receive or can get the source code. And you
+must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If
+the software is modified by someone else and passed on, we want its recipients
+to know that what they have is not the original, so that any problems introduced
+by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will individually
+obtain patent licenses, in effect making the program proprietary. To prevent
+this, we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms
+of this General Public License. The "Program", below, refers to any such program
+or work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or translated
+into another language. (Hereinafter, translation is included without limitation
+in the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running the Program
+is not restricted, and the output from the Program is covered only if its
+contents constitute a work based on the Program (independent of having been
+made by running the Program). Whether that is true depends on what the Program
+does.
+
+1. You may copy and distribute verbatim copies of the Program's source code
+as you receive it, in any medium, provided that you conspicuously and appropriately
+publish on each copy an appropriate copyright notice and disclaimer of warranty;
+keep intact all the notices that refer to this License and to the absence
+of any warranty; and give any other recipients of the Program a copy of this
+License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it,
+thus forming a work based on the Program, and copy and distribute such modifications
+or work under the terms of Section 1 above, provided that you also meet all
+of these conditions:
+
+a) You must cause the modified files to carry prominent notices stating that
+you changed the files and the date of any change.
+
+b) You must cause any work that you distribute or publish, that in whole or
+in part contains or is derived from the Program or any part thereof, to be
+licensed as a whole at no charge to all third parties under the terms of this
+License.
+
+c) If the modified program normally reads commands interactively when run,
+you must cause it, when started running for such interactive use in the most
+ordinary way, to print or display an announcement including an appropriate
+copyright notice and a notice that there is no warranty (or else, saying that
+you provide a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this License.
+(Exception: if the Program itself is interactive but does not normally print
+such an announcement, your work based on the Program is not required to print
+an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Program, the distribution of the whole must be
+on the terms of this License, whose permissions for other licensees extend
+to the entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise
+the right to control the distribution of derivative or collective works based
+on the Program.
+
+In addition, mere aggregation of another work not based on the Program with
+the Program (or with a work based on the Program) on a volume of a storage
+or distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may copy and distribute the Program (or a work based on it, under Section
+2) in object code or executable form under the terms of Sections 1 and 2 above
+provided that you also do one of the following:
+
+a) Accompany it with the complete corresponding machine-readable source code,
+which must be distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+b) Accompany it with a written offer, valid for at least three years, to give
+any third party, for a charge no more than your cost of physically performing
+source distribution, a complete machine-readable copy of the corresponding
+source code, to be distributed under the terms of Sections 1 and 2 above on
+a medium customarily used for software interchange; or,
+
+c) Accompany it with the information you received as to the offer to distribute
+corresponding source code. (This alternative is allowed only for noncommercial
+distribution and only if you received the program in object code or executable
+form with such an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all
+the source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and installation
+of the executable. However, as a special exception, the source code distributed
+need not include anything that is normally distributed (in either source or
+binary form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component itself
+accompanies the executable.
+
+If distribution of executable or object code is made by offering access to
+copy from a designated place, then offering equivalent access to copy the
+source code from the same place counts as distribution of the source code,
+even though third parties are not compelled to copy the source along with
+the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except
+as expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program is void, and will automatically terminate
+your rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses terminated
+so long as such parties remain in full compliance.
+
+5. You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Program or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the Program
+(or any work based on the Program), you indicate your acceptance of this License
+to do so, and all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the Program),
+the recipient automatically receives a license from the original licensor
+to copy, distribute or modify the Program subject to these terms and conditions.
+You may not impose any further restrictions on the recipients' exercise of
+the rights granted herein. You are not responsible for enforcing compliance
+by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent infringement
+or for any other reason (not limited to patent issues), conditions are imposed
+on you (whether by court order, agreement or otherwise) that contradict the
+conditions of this License, they do not excuse you from the conditions of
+this License. If you cannot distribute so as to satisfy simultaneously your
+obligations under this License and any other pertinent obligations, then as
+a consequence you may not distribute the Program at all. For example, if a
+patent license would not permit royalty-free redistribution of the Program
+by all those who receive copies directly or indirectly through you, then the
+only way you could satisfy both it and this License would be to refrain entirely
+from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and
+the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents
+or other property right claims or to contest validity of any such claims;
+this section has the sole purpose of protecting the integrity of the free
+software distribution system, which is implemented by public license practices.
+Many people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose
+that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Program under this License may add an explicit geographical
+distribution limitation excluding those countries, so that distribution is
+permitted only in or among countries not thus excluded. In such case, this
+License incorporates the limitation as if written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of
+the General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Program does not specify a version number of this License, you may choose
+any version ever published by the Free Software Foundation.
+

+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software Foundation,
+write to the Free Software Foundation; we sometimes make exceptions for this.
+Our decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing and reuse
+of software generally.

+THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE

+
+Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <https://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <https://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU LIBRARY GENERAL PUBLIC LICENSE
+
+Version 2, June 1991 Copyright (C) 1991 Free Software Foundation, Inc.
+
+51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is numbered 2 because
+it goes with version 2 of the ordinary GPL.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public Licenses are intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users.
+
+This license, the Library General Public License, applies to some specially
+designated Free Software Foundation software, and to any other libraries whose
+authors decide to use it. You can use it for your libraries, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of
+the library, or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You must
+make sure that they, too, receive or can get the source code. If you link
+a program with the library, you must provide complete object files to the
+recipients so that they can relink them with the library, after making changes
+to the library and recompiling it. And you must show them these terms so they
+know their rights.
+
+Our method of protecting your rights has two steps: (1) copyright the library,
+and (2) offer you this license which gives you legal permission to copy, distribute
+and/or modify the library.
+
+Also, for each distributor's protection, we want to make certain that everyone
+understands that there is no warranty for this free library. If the library
+is modified by someone else and passed on, we want its recipients to know
+that what they have is not the original version, so that any problems introduced
+by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that companies distributing free software will individually
+obtain patent licenses, thus in effect transforming the program into proprietary
+software. To prevent this, we have made it clear that any patent must be licensed
+for everyone's free use or not licensed at all.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License, which was designed for utility programs. This license,
+the GNU Library General Public License, applies to certain designated libraries.
+This license is quite different from the ordinary one; be sure to read it
+in full, and don't assume that anything in it is the same as in the ordinary
+license.
+
+The reason we have a separate public license for some libraries is that they
+blur the distinction we usually make between modifying or adding to a program
+and simply using it. Linking a program with a library, without changing the
+library, is in some sense simply using the library, and is analogous to running
+a utility program or application program. However, in a textual and legal
+sense, the linked executable is a combined work, a derivative of the original
+library, and the ordinary General Public License treats it as such.
+
+Because of this blurred distinction, using the ordinary General Public License
+for libraries did not effectively promote software sharing, because most developers
+did not use the libraries. We concluded that weaker conditions might promote
+sharing better.
+
+However, unrestricted linking of non-free programs would deprive the users
+of those programs of all benefit from the free status of the libraries themselves.
+This Library General Public License is intended to permit developers of non-free
+programs to use free libraries, while preserving your freedom as a user of
+such programs to change the free libraries that are incorporated in them.
+(We have not seen how to achieve this as regards changes in header files,
+but we have achieved it as regards changes in the actual functions of the
+Library.) The hope is that this will lead to faster development of free libraries.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code derived
+from the library, while the latter only works together with the library.
+
+Note that it is possible for a library to be covered by the ordinary General
+Public License rather than by this special one.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library which contains a
+notice placed by the copyright holder or other authorized party saying it
+may be distributed under the terms of this Library General Public License
+(also called "this License"). Each licensee is addressed as "you".
+
+A "library" means a collection of software functions and/or data prepared
+so as to be conveniently linked with application programs (which use some
+of those functions and data) to form executables.
+
+The "Library", below, refers to any such software library or work which has
+been distributed under these terms. A "work based on the Library" means either
+the Library or any derivative work under copyright law: that is to say, a
+work containing the Library or a portion of it, either verbatim or with modifications
+and/or translated straightforwardly into another language. (Hereinafter, translation
+is included without limitation in the term "modification".)
+
+"Source code" for a work means the preferred form of the work for making modifications
+to it. For a library, complete source code means all the source code for all
+modules it contains, plus any associated interface definition files, plus
+the scripts used to control compilation and installation of the library.
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running a program
+using the Library is not restricted, and output from such a program is covered
+only if its contents constitute a work based on the Library (independent of
+the use of the Library in a tool for writing it). Whether that is true depends
+on what the Library does and what the program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and disclaimer
+of warranty; keep intact all the notices that refer to this License and to
+the absence of any warranty; and distribute a copy of this License along with
+the Library.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such modifications
+or work under the terms of Section 1 above, provided that you also meet all
+of these conditions:
+
+      a) The modified work must itself be a software library.
+
+b) You must cause the files modified to carry prominent notices stating that
+you changed the files and the date of any change.
+
+c) You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+d) If a facility in the modified Library refers to a function or a table of
+data to be supplied by an application program that uses the facility, other
+than as an argument passed when the facility is invoked, then you must make
+a good faith effort to ensure that, in the event an application does not supply
+such function or table, the facility still operates, and performs whatever
+part of its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has a purpose
+that is entirely well-defined independent of the application. Therefore, Subsection
+2d requires that any application-supplied function or table used by this function
+must be optional: if the application does not supply it, the square root function
+must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Library, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Library, the distribution of the whole must be
+on the terms of this License, whose permissions for other licensees extend
+to the entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise
+the right to control the distribution of derivative or collective works based
+on the Library.
+
+In addition, mere aggregation of another work not based on the Library with
+the Library (or with a work based on the Library) on a volume of a storage
+or distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public License
+instead of this License to a given copy of the Library. To do this, you must
+alter all the notices that refer to this License, so that they refer to the
+ordinary GNU General Public License, version 2, instead of to this License.
+(If a newer version than version 2 of the ordinary GNU General Public License
+has appeared, then you can specify that version instead if you wish.) Do not
+make any other change in these notices.
+
+Once this change is made in a given copy, it is irreversible for that copy,
+so the ordinary GNU General Public License applies to all subsequent copies
+and derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the Library
+into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you accompany it with the complete corresponding
+machine-readable source code, which must be distributed under the terms of
+Sections 1 and 2 above on a medium customarily used for software interchange.
+
+If distribution of object code is made by offering access to copy from a designated
+place, then offering equivalent access to copy the source code from the same
+place satisfies the requirement to distribute the source code, even though
+third parties are not compelled to copy the source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with it,
+is called a "work that uses the Library". Such a work, in isolation, is not
+a derivative work of the Library, and therefore falls outside the scope of
+this License.
+
+However, linking a "work that uses the Library" with the Library creates an
+executable that is a derivative of the Library (because it contains portions
+of the Library), rather than a "work that uses the library". The executable
+is therefore covered by this License. Section 6 states terms for distribution
+of such executables.
+
+When a "work that uses the Library" uses material from a header file that
+is part of the Library, the object code for the work may be a derivative work
+of the Library even though the source code is not. Whether this is true is
+especially significant if the work can be linked without the Library, or if
+the work is itself a library. The threshold for this to be true is not precisely
+defined by law.
+
+If such an object file uses only numerical parameters, data structure layouts
+and accessors, and small macros and small inline functions (ten lines or less
+in length), then the use of the object file is unrestricted, regardless of
+whether it is legally a derivative work. (Executables containing this object
+code plus portions of the Library will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may distribute
+the object code for the work under the terms of Section 6. Any executables
+containing that work also fall under Section 6, whether or not they are linked
+directly with the Library itself.
+
+6. As an exception to the Sections above, you may also compile or link a "work
+that uses the Library" with the Library to produce a work containing portions
+of the Library, and distribute that work under terms of your choice, provided
+that the terms permit modification of the work for the customer's own use
+and reverse engineering for debugging such modifications.
+
+You must give prominent notice with each copy of the work that the Library
+is used in it and that the Library and its use are covered by this License.
+You must supply a copy of this License. If the work during execution displays
+copyright notices, you must include the copyright notice for the Library among
+them, as well as a reference directing the user to the copy of this License.
+Also, you must do one of these things:
+
+a) Accompany the work with the complete corresponding machine-readable source
+code for the Library including whatever changes were used in the work (which
+must be distributed under Sections 1 and 2 above); and, if the work is an
+executable linked with the Library, with the complete machine-readable "work
+that uses the Library", as object code and/or source code, so that the user
+can modify the Library and then relink to produce a modified executable containing
+the modified Library. (It is understood that the user who changes the contents
+of definitions files in the Library will not necessarily be able to recompile
+the application to use the modified definitions.)
+
+b) Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above, for
+a charge no more than the cost of performing this distribution.
+
+c) If distribution of the work is made by offering access to copy from a designated
+place, offer equivalent access to copy the above specified materials from
+the same place.
+
+d) Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+For an executable, the required form of the "work that uses the Library" must
+include any data and utility programs needed for reproducing the executable
+from it. However, as a special exception, the source code distributed need
+not include anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the operating
+system on which the executable runs, unless that component itself accompanies
+the executable.
+
+It may happen that this requirement contradicts the license restrictions of
+other proprietary libraries that do not normally accompany the operating system.
+Such a contradiction means you cannot use both them and the Library together
+in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library side-by-side
+in a single library together with other library facilities not covered by
+this License, and distribute such a combined library, provided that the separate
+distribution of the work based on the Library and of the other library facilities
+is otherwise permitted, and provided that you do these two things:
+
+a) Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities. This must be distributed
+under the terms of the Sections above.
+
+b) Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the accompanying
+uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the Library
+except as expressly provided under this License. Any attempt otherwise to
+copy, modify, sublicense, link with, or distribute the Library is void, and
+will automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will not
+have their licenses terminated so long as such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Library or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the Library
+(or any work based on the Library), you indicate your acceptance of this License
+to do so, and all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+10. Each time you redistribute the Library (or any work based on the Library),
+the recipient automatically receives a license from the original licensor
+to copy, distribute, link with or modify the Library subject to these terms
+and conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties to this License.
+
+11. If, as a consequence of a court judgment or allegation of patent infringement
+or for any other reason (not limited to patent issues), conditions are imposed
+on you (whether by court order, agreement or otherwise) that contradict the
+conditions of this License, they do not excuse you from the conditions of
+this License. If you cannot distribute so as to satisfy simultaneously your
+obligations under this License and any other pertinent obligations, then as
+a consequence you may not distribute the Library at all. For example, if a
+patent license would not permit royalty-free redistribution of the Library
+by all those who receive copies directly or indirectly through you, then the
+only way you could satisfy both it and this License would be to refrain entirely
+from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents
+or other property right claims or to contest validity of any such claims;
+this section has the sole purpose of protecting the integrity of the free
+software distribution system which is implemented by public license practices.
+Many people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose
+that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Library under this License may add an explicit geographical
+distribution limitation excluding those countries, so that distribution is
+permitted only in or among countries not thus excluded. In such case, this
+License incorporates the limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+the Library General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to address
+new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Library does not specify a license version number, you may choose any version
+ever published by the Free Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free programs
+whose distribution conditions are incompatible with these, write to the author
+to ask for permission. For software which is copyrighted by the Free Software
+Foundation, write to the Free Software Foundation; we sometimes make exceptions
+for this. Our decision will be guided by the two goals of preserving the free
+status of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+   NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
+FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
+OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
+OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
+OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
+HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest possible
+use to the public, we recommend making it free software that everyone can
+redistribute and change. You can do so by permitting redistribution under
+these terms (or, alternatively, under the terms of the ordinary General Public
+License).
+
+To apply these terms, attach the following notices to the library. It is safest
+to attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the "copyright"
+line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.

+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS

+GNU LESSER GENERAL PUBLIC LICENSE
+
+Version 2.1, February 1999
+
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as the
+successor of the GNU Library Public License, version 2, hence the version
+number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public Licenses are intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software Foundation
+and other authors who decide to use it. You can use it too, but we suggest
+you first think carefully about whether this license or the ordinary General
+Public License is the better strategy to use in any particular case, based
+on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not price.
+Our General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish); that you receive source code or can get it if you want it; that you
+can change the software and use pieces of it in new free programs; and that
+you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid distributors
+to deny you these rights or to ask you to surrender these rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of
+the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You must
+make sure that they, too, receive or can get the source code. If you link
+other code with the library, you must provide complete object files to the
+recipients, so that they can relink them with the library after making changes
+to the library and recompiling it. And you must show them these terms so they
+know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the library,
+and (2) we offer you this license, which gives you legal permission to copy,
+distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any free
+program. We wish to make sure that a company cannot effectively restrict the
+users of a free program by obtaining a restrictive license from a patent holder.
+Therefore, we insist that any patent license obtained for a version of the
+library must be consistent with the full freedom of use specified in this
+license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public License,
+applies to certain designated libraries, and is quite different from the ordinary
+General Public License. We use this license for certain libraries in order
+to permit linking those libraries into non-free programs.
+
+When a program is linked with a library, whether statically or using a shared
+library, the combination of the two is legally speaking a combined work, a
+derivative of the original library. The ordinary General Public License therefore
+permits such linking only if the entire combination fits its criteria of freedom.
+The Lesser General Public License permits more lax criteria for linking other
+code with the library.
+
+We call this license the "Lesser" General Public License because it does Less
+to protect the user's freedom than the ordinary General Public License. It
+also provides other free software developers Less of an advantage over competing
+non-free programs. These disadvantages are the reason we use the ordinary
+General Public License for many libraries. However, the Lesser license provides
+advantages in certain special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage the
+widest possible use of a certain library, so that it becomes a de-facto standard.
+To achieve this, non-free programs must be allowed to use the library. A more
+frequent case is that a free library does the same job as widely used non-free
+libraries. In this case, there is little to gain by limiting the free library
+to free software only, so we use the Lesser General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free software. For
+example, permission to use the GNU C Library in non-free programs enables
+many more people to use the whole GNU operating system, as well as its variant,
+the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a modified
+version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code derived
+from the library, whereas the latter must be combined with the library in
+order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Lesser General
+Public License (also called "this License"). Each licensee is addressed as
+"you".
+
+A "library" means a collection of software functions and/or data prepared
+so as to be conveniently linked with application programs (which use some
+of those functions and data) to form executables.
+
+The "Library", below, refers to any such software library or work which has
+been distributed under these terms. A "work based on the Library" means either
+the Library or any derivative work under copyright law: that is to say, a
+work containing the Library or a portion of it, either verbatim or with modifications
+and/or translated straightforwardly into another language. (Hereinafter, translation
+is included without limitation in the term "modification".)
+
+"Source code" for a work means the preferred form of the work for making modifications
+to it. For a library, complete source code means all the source code for all
+modules it contains, plus any associated interface definition files, plus
+the scripts used to control compilation and installation of the library.
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running a program
+using the Library is not restricted, and output from such a program is covered
+only if its contents constitute a work based on the Library (independent of
+the use of the Library in a tool for writing it). Whether that is true depends
+on what the Library does and what the program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and disclaimer
+of warranty; keep intact all the notices that refer to this License and to
+the absence of any warranty; and distribute a copy of this License along with
+the Library.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such modifications
+or work under the terms of Section 1 above, provided that you also meet all
+of these conditions:
+
+      a) The modified work must itself be a software library.
+
+b) You must cause the files modified to carry prominent notices stating that
+you changed the files and the date of any change.
+
+c) You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+d) If a facility in the modified Library refers to a function or a table of
+data to be supplied by an application program that uses the facility, other
+than as an argument passed when the facility is invoked, then you must make
+a good faith effort to ensure that, in the event an application does not supply
+such function or table, the facility still operates, and performs whatever
+part of its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has a purpose
+that is entirely well-defined independent of the application. Therefore, Subsection
+2d requires that any application-supplied function or table used by this function
+must be optional: if the application does not supply it, the square root function
+must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Library, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Library, the distribution of the whole must be
+on the terms of this License, whose permissions for other licensees extend
+to the entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise
+the right to control the distribution of derivative or collective works based
+on the Library.
+
+In addition, mere aggregation of another work not based on the Library with
+the Library (or with a work based on the Library) on a volume of a storage
+or distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public License
+instead of this License to a given copy of the Library. To do this, you must
+alter all the notices that refer to this License, so that they refer to the
+ordinary GNU General Public License, version 2, instead of to this License.
+(If a newer version than version 2 of the ordinary GNU General Public License
+has appeared, then you can specify that version instead if you wish.) Do not
+make any other change in these notices.
+
+Once this change is made in a given copy, it is irreversible for that copy,
+so the ordinary GNU General Public License applies to all subsequent copies
+and derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the Library
+into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you accompany it with the complete corresponding
+machine-readable source code, which must be distributed under the terms of
+Sections 1 and 2 above on a medium customarily used for software interchange.
+
+If distribution of object code is made by offering access to copy from a designated
+place, then offering equivalent access to copy the source code from the same
+place satisfies the requirement to distribute the source code, even though
+third parties are not compelled to copy the source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with it,
+is called a "work that uses the Library". Such a work, in isolation, is not
+a derivative work of the Library, and therefore falls outside the scope of
+this License.
+
+However, linking a "work that uses the Library" with the Library creates an
+executable that is a derivative of the Library (because it contains portions
+of the Library), rather than a "work that uses the library". The executable
+is therefore covered by this License. Section 6 states terms for distribution
+of such executables.
+
+When a "work that uses the Library" uses material from a header file that
+is part of the Library, the object code for the work may be a derivative work
+of the Library even though the source code is not. Whether this is true is
+especially significant if the work can be linked without the Library, or if
+the work is itself a library. The threshold for this to be true is not precisely
+defined by law.
+
+If such an object file uses only numerical parameters, data structure layouts
+and accessors, and small macros and small inline functions (ten lines or less
+in length), then the use of the object file is unrestricted, regardless of
+whether it is legally a derivative work. (Executables containing this object
+code plus portions of the Library will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may distribute
+the object code for the work under the terms of Section 6. Any executables
+containing that work also fall under Section 6, whether or not they are linked
+directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a "work
+that uses the Library" with the Library to produce a work containing portions
+of the Library, and distribute that work under terms of your choice, provided
+that the terms permit modification of the work for the customer's own use
+and reverse engineering for debugging such modifications.
+
+You must give prominent notice with each copy of the work that the Library
+is used in it and that the Library and its use are covered by this License.
+You must supply a copy of this License. If the work during execution displays
+copyright notices, you must include the copyright notice for the Library among
+them, as well as a reference directing the user to the copy of this License.
+Also, you must do one of these things:
+
+a) Accompany the work with the complete corresponding machine-readable source
+code for the Library including whatever changes were used in the work (which
+must be distributed under Sections 1 and 2 above); and, if the work is an
+executable linked with the Library, with the complete machine-readable "work
+that uses the Library", as object code and/or source code, so that the user
+can modify the Library and then relink to produce a modified executable containing
+the modified Library. (It is understood that the user who changes the contents
+of definitions files in the Library will not necessarily be able to recompile
+the application to use the modified definitions.)
+
+b) Use a suitable shared library mechanism for linking with the Library. A
+suitable mechanism is one that (1) uses at run time a copy of the library
+already present on the user's computer system, rather than copying library
+functions into the executable, and (2) will operate properly with a modified
+version of the library, if the user installs one, as long as the modified
+version is interface-compatible with the version that the work was made with.
+
+c) Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above, for
+a charge no more than the cost of performing this distribution.
+
+d) If distribution of the work is made by offering access to copy from a designated
+place, offer equivalent access to copy the above specified materials from
+the same place.
+
+e) Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+For an executable, the required form of the "work that uses the Library" must
+include any data and utility programs needed for reproducing the executable
+from it. However, as a special exception, the materials to be distributed
+need not include anything that is normally distributed (in either source or
+binary form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component itself
+accompanies the executable.
+
+It may happen that this requirement contradicts the license restrictions of
+other proprietary libraries that do not normally accompany the operating system.
+Such a contradiction means you cannot use both them and the Library together
+in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library side-by-side
+in a single library together with other library facilities not covered by
+this License, and distribute such a combined library, provided that the separate
+distribution of the work based on the Library and of the other library facilities
+is otherwise permitted, and provided that you do these two things:
+
+a) Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities. This must be distributed
+under the terms of the Sections above.
+
+b) Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the accompanying
+uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the Library
+except as expressly provided under this License. Any attempt otherwise to
+copy, modify, sublicense, link with, or distribute the Library is void, and
+will automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will not
+have their licenses terminated so long as such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Library or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the Library
+(or any work based on the Library), you indicate your acceptance of this License
+to do so, and all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+10. Each time you redistribute the Library (or any work based on the Library),
+the recipient automatically receives a license from the original licensor
+to copy, distribute, link with or modify the Library subject to these terms
+and conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent infringement
+or for any other reason (not limited to patent issues), conditions are imposed
+on you (whether by court order, agreement or otherwise) that contradict the
+conditions of this License, they do not excuse you from the conditions of
+this License. If you cannot distribute so as to satisfy simultaneously your
+obligations under this License and any other pertinent obligations, then as
+a consequence you may not distribute the Library at all. For example, if a
+patent license would not permit royalty-free redistribution of the Library
+by all those who receive copies directly or indirectly through you, then the
+only way you could satisfy both it and this License would be to refrain entirely
+from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents
+or other property right claims or to contest validity of any such claims;
+this section has the sole purpose of protecting the integrity of the free
+software distribution system which is implemented by public license practices.
+Many people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose
+that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Library under this License may add an explicit geographical
+distribution limitation excluding those countries, so that distribution is
+permitted only in or among countries not thus excluded. In such case, this
+License incorporates the limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+the Lesser General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to address
+new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Library does not specify a license version number, you may choose any version
+ever published by the Free Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free programs
+whose distribution conditions are incompatible with these, write to the author
+to ask for permission. For software which is copyrighted by the Free Software
+Foundation, write to the Free Software Foundation; we sometimes make exceptions
+for this. Our decision will be guided by the two goals of preserving the free
+status of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+   NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
+FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
+OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
+OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
+OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
+HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest possible
+use to the public, we recommend making it free software that everyone can
+redistribute and change. You can do so by permitting redistribution under
+these terms (or, alternatively, under the terms of the ordinary General Public
+License).
+
+To apply these terms, attach the following notices to the library. It is safest
+to attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the "copyright"
+line and a pointer to where the full notice is found.
+
+< one line to give the library's name and an idea of what it does. >

+GNU LESSER GENERAL PUBLIC LICENSE
+
+Version 2.1, February 1999
+
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as the
+successor of the GNU Library Public License, version 2, hence the version
+number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public Licenses are intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software Foundation
+and other authors who decide to use it. You can use it too, but we suggest
+you first think carefully about whether this license or the ordinary General
+Public License is the better strategy to use in any particular case, based
+on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not price.
+Our General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish); that you receive source code or can get it if you want it; that you
+can change the software and use pieces of it in new free programs; and that
+you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid distributors
+to deny you these rights or to ask you to surrender these rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of
+the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You must
+make sure that they, too, receive or can get the source code. If you link
+other code with the library, you must provide complete object files to the
+recipients, so that they can relink them with the library after making changes
+to the library and recompiling it. And you must show them these terms so they
+know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the library,
+and (2) we offer you this license, which gives you legal permission to copy,
+distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any free
+program. We wish to make sure that a company cannot effectively restrict the
+users of a free program by obtaining a restrictive license from a patent holder.
+Therefore, we insist that any patent license obtained for a version of the
+library must be consistent with the full freedom of use specified in this
+license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public License,
+applies to certain designated libraries, and is quite different from the ordinary
+General Public License. We use this license for certain libraries in order
+to permit linking those libraries into non-free programs.
+
+When a program is linked with a library, whether statically or using a shared
+library, the combination of the two is legally speaking a combined work, a
+derivative of the original library. The ordinary General Public License therefore
+permits such linking only if the entire combination fits its criteria of freedom.
+The Lesser General Public License permits more lax criteria for linking other
+code with the library.
+
+We call this license the "Lesser" General Public License because it does Less
+to protect the user's freedom than the ordinary General Public License. It
+also provides other free software developers Less of an advantage over competing
+non-free programs. These disadvantages are the reason we use the ordinary
+General Public License for many libraries. However, the Lesser license provides
+advantages in certain special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage the
+widest possible use of a certain library, so that it becomes a de-facto standard.
+To achieve this, non-free programs must be allowed to use the library. A more
+frequent case is that a free library does the same job as widely used non-free
+libraries. In this case, there is little to gain by limiting the free library
+to free software only, so we use the Lesser General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free software. For
+example, permission to use the GNU C Library in non-free programs enables
+many more people to use the whole GNU operating system, as well as its variant,
+the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a modified
+version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code derived
+from the library, whereas the latter must be combined with the library in
+order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Lesser General
+Public License (also called "this License"). Each licensee is addressed as
+"you".
+
+A "library" means a collection of software functions and/or data prepared
+so as to be conveniently linked with application programs (which use some
+of those functions and data) to form executables.
+
+The "Library", below, refers to any such software library or work which has
+been distributed under these terms. A "work based on the Library" means either
+the Library or any derivative work under copyright law: that is to say, a
+work containing the Library or a portion of it, either verbatim or with modifications
+and/or translated straightforwardly into another language. (Hereinafter, translation
+is included without limitation in the term "modification".)
+
+"Source code" for a work means the preferred form of the work for making modifications
+to it. For a library, complete source code means all the source code for all
+modules it contains, plus any associated interface definition files, plus
+the scripts used to control compilation and installation of the library.
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running a program
+using the Library is not restricted, and output from such a program is covered
+only if its contents constitute a work based on the Library (independent of
+the use of the Library in a tool for writing it). Whether that is true depends
+on what the Library does and what the program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and disclaimer
+of warranty; keep intact all the notices that refer to this License and to
+the absence of any warranty; and distribute a copy of this License along with
+the Library.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such modifications
+or work under the terms of Section 1 above, provided that you also meet all
+of these conditions:
+
+      a) The modified work must itself be a software library.
+
+b) You must cause the files modified to carry prominent notices stating that
+you changed the files and the date of any change.
+
+c) You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+d) If a facility in the modified Library refers to a function or a table of
+data to be supplied by an application program that uses the facility, other
+than as an argument passed when the facility is invoked, then you must make
+a good faith effort to ensure that, in the event an application does not supply
+such function or table, the facility still operates, and performs whatever
+part of its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has a purpose
+that is entirely well-defined independent of the application. Therefore, Subsection
+2d requires that any application-supplied function or table used by this function
+must be optional: if the application does not supply it, the square root function
+must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Library, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Library, the distribution of the whole must be
+on the terms of this License, whose permissions for other licensees extend
+to the entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise
+the right to control the distribution of derivative or collective works based
+on the Library.
+
+In addition, mere aggregation of another work not based on the Library with
+the Library (or with a work based on the Library) on a volume of a storage
+or distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public License
+instead of this License to a given copy of the Library. To do this, you must
+alter all the notices that refer to this License, so that they refer to the
+ordinary GNU General Public License, version 2, instead of to this License.
+(If a newer version than version 2 of the ordinary GNU General Public License
+has appeared, then you can specify that version instead if you wish.) Do not
+make any other change in these notices.
+
+Once this change is made in a given copy, it is irreversible for that copy,
+so the ordinary GNU General Public License applies to all subsequent copies
+and derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the Library
+into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you accompany it with the complete corresponding
+machine-readable source code, which must be distributed under the terms of
+Sections 1 and 2 above on a medium customarily used for software interchange.
+
+If distribution of object code is made by offering access to copy from a designated
+place, then offering equivalent access to copy the source code from the same
+place satisfies the requirement to distribute the source code, even though
+third parties are not compelled to copy the source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with it,
+is called a "work that uses the Library". Such a work, in isolation, is not
+a derivative work of the Library, and therefore falls outside the scope of
+this License.
+
+However, linking a "work that uses the Library" with the Library creates an
+executable that is a derivative of the Library (because it contains portions
+of the Library), rather than a "work that uses the library". The executable
+is therefore covered by this License. Section 6 states terms for distribution
+of such executables.
+
+When a "work that uses the Library" uses material from a header file that
+is part of the Library, the object code for the work may be a derivative work
+of the Library even though the source code is not. Whether this is true is
+especially significant if the work can be linked without the Library, or if
+the work is itself a library. The threshold for this to be true is not precisely
+defined by law.
+
+If such an object file uses only numerical parameters, data structure layouts
+and accessors, and small macros and small inline functions (ten lines or less
+in length), then the use of the object file is unrestricted, regardless of
+whether it is legally a derivative work. (Executables containing this object
+code plus portions of the Library will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may distribute
+the object code for the work under the terms of Section 6. Any executables
+containing that work also fall under Section 6, whether or not they are linked
+directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a "work
+that uses the Library" with the Library to produce a work containing portions
+of the Library, and distribute that work under terms of your choice, provided
+that the terms permit modification of the work for the customer's own use
+and reverse engineering for debugging such modifications.
+
+You must give prominent notice with each copy of the work that the Library
+is used in it and that the Library and its use are covered by this License.
+You must supply a copy of this License. If the work during execution displays
+copyright notices, you must include the copyright notice for the Library among
+them, as well as a reference directing the user to the copy of this License.
+Also, you must do one of these things:
+
+a) Accompany the work with the complete corresponding machine-readable source
+code for the Library including whatever changes were used in the work (which
+must be distributed under Sections 1 and 2 above); and, if the work is an
+executable linked with the Library, with the complete machine-readable "work
+that uses the Library", as object code and/or source code, so that the user
+can modify the Library and then relink to produce a modified executable containing
+the modified Library. (It is understood that the user who changes the contents
+of definitions files in the Library will not necessarily be able to recompile
+the application to use the modified definitions.)
+
+b) Use a suitable shared library mechanism for linking with the Library. A
+suitable mechanism is one that (1) uses at run time a copy of the library
+already present on the user's computer system, rather than copying library
+functions into the executable, and (2) will operate properly with a modified
+version of the library, if the user installs one, as long as the modified
+version is interface-compatible with the version that the work was made with.
+
+c) Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above, for
+a charge no more than the cost of performing this distribution.
+
+d) If distribution of the work is made by offering access to copy from a designated
+place, offer equivalent access to copy the above specified materials from
+the same place.
+
+e) Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+For an executable, the required form of the "work that uses the Library" must
+include any data and utility programs needed for reproducing the executable
+from it. However, as a special exception, the materials to be distributed
+need not include anything that is normally distributed (in either source or
+binary form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component itself
+accompanies the executable.
+
+It may happen that this requirement contradicts the license restrictions of
+other proprietary libraries that do not normally accompany the operating system.
+Such a contradiction means you cannot use both them and the Library together
+in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library side-by-side
+in a single library together with other library facilities not covered by
+this License, and distribute such a combined library, provided that the separate
+distribution of the work based on the Library and of the other library facilities
+is otherwise permitted, and provided that you do these two things:
+
+a) Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities. This must be distributed
+under the terms of the Sections above.
+
+b) Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the accompanying
+uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the Library
+except as expressly provided under this License. Any attempt otherwise to
+copy, modify, sublicense, link with, or distribute the Library is void, and
+will automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will not
+have their licenses terminated so long as such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Library or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the Library
+(or any work based on the Library), you indicate your acceptance of this License
+to do so, and all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+10. Each time you redistribute the Library (or any work based on the Library),
+the recipient automatically receives a license from the original licensor
+to copy, distribute, link with or modify the Library subject to these terms
+and conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent infringement
+or for any other reason (not limited to patent issues), conditions are imposed
+on you (whether by court order, agreement or otherwise) that contradict the
+conditions of this License, they do not excuse you from the conditions of
+this License. If you cannot distribute so as to satisfy simultaneously your
+obligations under this License and any other pertinent obligations, then as
+a consequence you may not distribute the Library at all. For example, if a
+patent license would not permit royalty-free redistribution of the Library
+by all those who receive copies directly or indirectly through you, then the
+only way you could satisfy both it and this License would be to refrain entirely
+from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents
+or other property right claims or to contest validity of any such claims;
+this section has the sole purpose of protecting the integrity of the free
+software distribution system which is implemented by public license practices.
+Many people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose
+that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Library under this License may add an explicit geographical
+distribution limitation excluding those countries, so that distribution is
+permitted only in or among countries not thus excluded. In such case, this
+License incorporates the limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+the Lesser General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to address
+new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Library does not specify a license version number, you may choose any version
+ever published by the Free Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free programs
+whose distribution conditions are incompatible with these, write to the author
+to ask for permission. For software which is copyrighted by the Free Software
+Foundation, write to the Free Software Foundation; we sometimes make exceptions
+for this. Our decision will be guided by the two goals of preserving the free
+status of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+   NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
+FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
+OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
+OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
+OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
+HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest possible
+use to the public, we recommend making it free software that everyone can
+redistribute and change. You can do so by permitting redistribution under
+these terms (or, alternatively, under the terms of the ordinary General Public
+License).
+
+To apply these terms, attach the following notices to the library. It is safest
+to attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the "copyright"
+line and a pointer to where the full notice is found.
+
+<one line to give the library's name and an idea of what it does.>
+

+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS

+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your school,
+if any, to sign a "copyright disclaimer" for the library, if necessary. Here

+GNU LESSER GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+This version of the GNU Lesser General Public License incorporates the terms
+and conditions of version 3 of the GNU General Public License, supplemented
+by the additional permissions listed below.
+
+   0. Additional Definitions.
+
+      
+
+As used herein, "this License" refers to version 3 of the GNU Lesser General
+Public License, and the "GNU GPL" refers to version 3 of the GNU General Public
+License.
+
+      
+
+"The Library" refers to a covered work governed by this License, other than
+an Application or a Combined Work as defined below.
+
+      
+
+An "Application" is any work that makes use of an interface provided by the
+Library, but which is not otherwise based on the Library. Defining a subclass
+of a class defined by the Library is deemed a mode of using an interface provided
+by the Library.
+
+      
+
+A "Combined Work" is a work produced by combining or linking an Application
+with the Library. The particular version of the Library with which the Combined
+Work was made is also called the "Linked Version".
+
+      
+
+The "Minimal Corresponding Source" for a Combined Work means the Corresponding
+Source for the Combined Work, excluding any source code for portions of the
+Combined Work that, considered in isolation, are based on the Application,
+and not on the Linked Version.
+
+      
+
+The "Corresponding Application Code" for a Combined Work means the object
+code and/or source code for the Application, including any data and utility
+programs needed for reproducing the Combined Work from the Application, but
+excluding the System Libraries of the Combined Work.
+
+   1. Exception to Section 3 of the GNU GPL.
+
+You may convey a covered work under sections 3 and 4 of this License without
+being bound by section 3 of the GNU GPL.
+
+   2. Conveying Modified Versions.
+
+If you modify a copy of the Library, and, in your modifications, a facility
+refers to a function or data to be supplied by an Application that uses the
+facility (other than as an argument passed when the facility is invoked),
+then you may convey a copy of the modified version:
+
+a) under this License, provided that you make a good faith effort to ensure
+that, in the event an Application does not supply the function or data, the
+facility still operates, and performs whatever part of its purpose remains
+meaningful, or
+
+b) under the GNU GPL, with none of the additional permissions of this License
+applicable to that copy.
+
+   3. Object Code Incorporating Material from Library Header Files.
+
+The object code form of an Application may incorporate material from a header
+file that is part of the Library. You may convey such object code under terms
+of your choice, provided that, if the incorporated material is not limited
+to numerical parameters, data structure layouts and accessors, or small macros,
+inline functions and templates (ten or fewer lines in length), you do both
+of the following:
+
+a) Give prominent notice with each copy of the object code that the Library
+is used in it and that the Library and its use are covered by this License.
+
+b) Accompany the object code with a copy of the GNU GPL and this license document.
+
+   4. Combined Works.
+
+You may convey a Combined Work under terms of your choice that, taken together,
+effectively do not restrict modification of the portions of the Library contained
+in the Combined Work and reverse engineering for debugging such modifications,
+if you also do each of the following:
+
+a) Give prominent notice with each copy of the Combined Work that the Library
+is used in it and that the Library and its use are covered by this License.
+
+b) Accompany the Combined Work with a copy of the GNU GPL and this license
+document.
+
+c) For a Combined Work that displays copyright notices during execution, include
+the copyright notice for the Library among these notices, as well as a reference
+directing the user to the copies of the GNU GPL and this license document.
+
+      d) Do one of the following:
+
+0) Convey the Minimal Corresponding Source under the terms of this License,
+and the Corresponding Application Code in a form suitable for, and under terms
+that permit, the user to recombine or relink the Application with a modified
+version of the Linked Version to produce a modified Combined Work, in the
+manner specified by section 6 of the GNU GPL for conveying Corresponding Source.
+
+1) Use a suitable shared library mechanism for linking with the Library. A
+suitable mechanism is one that (a) uses at run time a copy of the Library
+already present on the user's computer system, and (b) will operate properly
+with a modified version of the Library that is interface-compatible with the
+Linked Version.
+
+e) Provide Installation Information, but only if you would otherwise be required
+to provide such information under section 6 of the GNU GPL, and only to the
+extent that such information is necessary to install and execute a modified
+version of the Combined Work produced by recombining or relinking the Application
+with a modified version of the Linked Version. (If you use option 4d0, the
+Installation Information must accompany the Minimal Corresponding Source and
+Corresponding Application Code. If you use option 4d1, you must provide the
+Installation Information in the manner specified by section 6 of the GNU GPL
+for conveying Corresponding Source.)
+
+   5. Combined Libraries.
+
+You may place library facilities that are a work based on the Library side
+by side in a single library together with other library facilities that are
+not Applications and are not covered by this License, and convey such a combined
+library under terms of your choice, if you do both of the following:
+
+a) Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities, conveyed under the
+terms of this License.
+
+b) Give prominent notice with the combined library that part of it is a work
+based on the Library, and explaining where to find the accompanying uncombined
+form of the same work.
+
+   6. Revised Versions of the GNU Lesser General Public License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU Lesser General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to address
+new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library as you
+received it specifies that a certain numbered version of the GNU Lesser General
+Public License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that published version or of
+any later version published by the Free Software Foundation. If the Library
+as you received it does not specify a version number of the GNU Lesser General
+Public License, you may choose any version of the GNU Lesser General Public
+License ever published by the Free Software Foundation.
+
+If the Library as you received it specifies that a proxy can decide whether
+future versions of the GNU Lesser General Public License shall apply, that
+proxy's public statement of acceptance of any version is permanent authorization
+for you to choose that version for the Library.

+The Qt Company Qt LGPL Exception version 1.1
+
+As an additional permission to the GNU Lesser General Public License version 2.1, the object code form of a "work that uses the Library" may incorporate material from a header file that is part of the Library. You may distribute such object code under terms of your choice, provided that:
+
+   (i) the header files of the Library have not been modified; and
+
+   (ii) the incorporated material is limited to numerical parameters, data structure layouts, accessors, macros, inline functions and templates; and
+
+   (iii) you comply with the terms of Section 6 of the GNU Lesser General Public License version 2.1.
+
+Moreover, you may apply this exception to a modified version of the Library, provided that such modification does not involve copying material from the Library into the modified Library's header files unless such material is limited to
+
+   (i) numerical parameters;
+
+   (ii) data structure layouts;
+
+   (iii) accessors; and
+
+   (iv) small macros, templates and inline functions of five lines or less in length.
+
+Furthermore, you are not required to apply this additional permission to a modified version of the Library.
