# Slackware build script for rigel-engine

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# If you're wondering why I host my own source tarball instead of
# using the github one, it's because the github tarball is missing the
# submodules.

# If you're wondering why the package is called rigel-engine and not
# RigelEngine, it's because I dislike MixedCase package names. Not
# going to change it.
