# Note: this is a completely new-from-template znes.SlackBuild,
# written from scratch, for the "LTS" 2.x fork from xyproto. It shares
# no code with the old zsnes.SlackBuild for the 1.51 release.

# 20261016 bkw: update for v2.3.8.
# 20261012 bkw: update for v2.3.7.
# 20260930 bkw: update for v2.3.6, which adds 64-bit support!

# Patch does these things:
# - Install binary to /usr/games
# - Fix install permissions for icon, .desktop, metainfo (no +x).
# - Install man page to /usr/man (not /usr/share/man)
# - Install man page in man6.
# - Use full path to binary in .desktop file.
