# Runs the hacked build-image against this folder to compile hacked/ (the
# vendored InkyBlackness HackEd snapshot, see README.md) for Linux and
# Windows, entirely offline - every Go module dependency it needs was already
# fetched into the image by ./hacked-build-image.sh.
#
# Output lands in dist/ (both platforms, packaged as .tgz/.zip).
#
# Usage: ./hacked-build-run-image.sh [command...]
#   With no arguments, runs the image's baked-in build-hacked.sh (its default
#   CMD). Pass a command (e.g. `bash`) to get a shell in the build environment
#   instead, useful for debugging a failed build.
