doodle/Dockerfile

##
# Fully build and distribute Linux and Windows binaries for Project: Doodle.
#
# This is designed to be run from a fully initialized Doodle environment
# (you had run the bootstrap.py for your system, and the doodads and
# levelpacks are installed in the assets/ folder, and `make dist` would
# build a release quality game for your local machine).
#
# It will take your working directory (minus any platform-specific artifacts
# and git repos cloned in to your deps/ folder) and build them from a sane
# Debian base and generate full release artifacts for:
#
# - Linux (x86_64 and i686) as .rpm, .deb, .flatpak and .tar.gz
# - Windows (64-bit and 32-bit) as .zip
#
# Artifact outputs will be in the dist/mw/ folder.
