# Red Bear OS — C-7 recipe edit
#
# For each recipe that has a migration patch in
# local/patches/<name>/, this script:
#   1. Identifies the sed chains in the recipe's
#      [build].script that produced the migration patch
#      (these are the chains the patch was captured from).
#   2. Replaces those sed chains with a single
#      `cookbook_apply_patches` call.
#   3. Leaves any other sed chains (real Red Bear edits
#      NOT in the migration patch) alone.
#
# This is the C-7 step 2: migrate the recipe's build
# script from inline sed hacks to the durable external
# patch helper. After this runs, the inline sed is gone
# and the cookbook's idempotency check makes the patch
# apply-once-only.
