#
# packpanda - this is a tool that packages up a panda game into a
# convenient, easily-downloaded windows executable.  Packpanda runs on linux
# and windows - on linux, it builds .debs and .rpms, on windows it relies on
# NSIS, the nullsoft scriptable install system, to do the hard work.
#
# This is intentionally a very simplistic game-packer with very
# limited options.  The goal is simplicity, not feature richness.
# There are dozens of complex, powerful packaging tools already out
# there.  This one is for people who just want to do it quick and
# easy.
