# Slackware build script for mfe

# Originally written by Luis Henrique.
# Modified and now maintained by B. Watson <urchlay@slackware.uk>.
# Original version had no license. Modified version is
# licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20241005 bkw: BUILD=2.
# - take over maintenance.
# - fix it so it can actually launch mednafen (vblur => tblur).
# - get useless INSTALL out of doc dir.
# - update deps (configobj => python2-configobj).
# - new-style icons.
# - tweak .desktop file.
# - move binary to /usr/games.

# Note: mfe has been abandoned upstream, no new releases since 2013.
# This has been broken on SBo (incapable of starting mednafen) for
# 11 years, and nobody's complained about it. I've taken it over and
# fixed it, for now, but I won't be spending any more time on it. If
# you like and use mfe, *please* take over maintenanance from me!
