# 20230807 bkw: BUILD=4
# - take over maintenance.
# - fix segfault on startup.
# - binary in /usr/games.
# - replace icon with the one from Xenoveritas (and prescale it).
# - update .desktop file.

# Note: there is a maintained fork: https://github.com/Xenoveritas/abuse.
# However, I can't get their 0.9.1 release to work correctly: it
# compiles and starts up, but does not respond to either mouse or
# keyboard no matter what I try. So I'm sticking with the old 0.8 from
# Sam Hocevar, with a patch backported from Xenoveritas to fix the
# segfault on startup (which seems to have been introduced by the new
# g++ in Slackware 15.0).
