# This thing is very early-90s, and not very much fun to use (even
# for me, who prefers WindowMaker). However, I never had an Amiga;
# for someone who grew up with one, maybe this is how they expect GUIs
# to work.

# 20230427 bkw: update for v0.22pl2.
# - Switched upstreams. Apparently the github version I packaged was a
#   fork. Now I'm using the actual author's version. Thanks to luna on
#   IRC for finding the original site and the new release (also for
#   testing the previous version).
# - Fix issue with parallel make.
# - Clean up man page slightly.
