# Slackware build script for cgmadness

# Written by Zbigniew Baniewski <Zbigniew [dot] Baniewski [at] gmail [dot] com>

# 20220220 bkw: Modified by SlackBuilds.org, BUILD=2:
# - fix build on 15.0.
# - move executable to /usr/games.
# ! THIS IS STILL BROKEN: it now builds an OK-looking Slackware package,
#   but it segfaults on startup.
