# 20250614 bkw: update for v1.1.2. this means SDL2, which lacks .s3m
# (mod) support on Slackware so I had to convert decision.s3m to an
# .ogg (with milkytracker and oggenc), then patch the code to load
# the .ogg.

# 20230107 bkw: BUILD=3, add doinst.sh, fix man page permission.
# 20211016 bkw: BUILD=2
# - add icons and .desktop
