Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

# Assumptions:
|
|
# - The header files are in C, with only C89 comments.
|
|
# - No use of macros with parameters.
|
|
# - All global declarations are marked with 'extern'.
|
|
# - All declarations end in ';' on the same line.
|
|
# - Not more than one symbol is declared in a declaration.
|
|
|
|
# This script requires GNU sed.
