# Package a Legend of Zelda: A Link to the Past release: a SETUP PACK.
#
# The zip does not contain the game. It contains a setup program (the host
# built with -DSNESRECOMP_SETUP_HOST=ON, i.e. without recompiled code), the
# recompiler and this source tree. On first run the player picks their own
# ROM and the launcher recompiles and rebuilds locally. No ROM, no src/gen,
# no recomp/funcs.h ever leaves this tree in a zip -- the framework's packager
# enforces that mechanically.
#
# Usage:
#   scripts/package_release.sh [<build-dir>] [<platform-tag>] [--embed-toolchain]
#
# Both positionals are optional; BUILD_DIR and PLATFORM still work as env vars.
# Defaults: build, and the host's own <os>-<arch>. --embed-toolchain copies
# the cmake-clang-v1 pack named by RETCOMM_TOOLCHAIN_DIR into the zip so the
# player downloads nothing.
#
# Writes: dist/legendofzeldaalinktothepast-<VERSION>-<platform-tag>.zip

# A silent exit is the worst outcome a packaging step can have: the first
# Windows CI run died here with exit 1 and not one line of output. Name the
# command and line instead of leaving the reader to bisect a shell script.
