# 20230605 bkw:
# - new maintainer.
# - update for v0.9.13.
# - fix typo in .desktop file.
# - fix doinst.sh.
# - remove zziplib from REQUIRES (desmume doesn't use it at all).
# - remove gtkglext from REQUIRES (desmume doesn't use it, even though
#   the README.LIN claims it does).
# - remove mention of optional lua dep in README, because it's not real
#   (see src/frontend/posix/meson.build; it's commented out).

# Notes:

# agg and soundtouch are actually optional. leave them in REQUIRES for
# now because I'm not feeling motivated enough to test what happens if
# you build without them.
