# Slackware build script for dmagnetic

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Note: no desktop integration or icons here. This application has to
# be run from the command line, unless the user's gone to the trouble
# of creating an .ini file... and even then you have to put the game
# name on the command line (so you'd need 7 .desktop files, none of
# which would work OOTB).

# MANVER is separate in case upstream produces e.g. a version 0.32.1
# but keeps the manual version at 0.32. No idea if this will ever
# happen. The manual source is available, as TeX source, but I see no
# reason to build it instead of using the prebuilt PDF file.

# 20230820 bkw: update for v0.37.
# 20230128 bkw: update for v0.36 (that was quick!)
# 20230112 bkw: update for v0.34.
# 20220316 bkw: BUILD=2, derp, gzip the man pages.
