# Slackware build script for eduke32

# Written by B. Watson (yalhcru@gmail.com)

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

# 20160808 bkw:
# - update for 20160704_5811
# - install samples/ to the doc dir, not the game data dir
# - rework wrapper script to let mods like bloodcm be installed
#   system-wide in /usr/share/games/eduke32
# - add compilefix.diff to get the tools to build
# - support SDL2 build, add SDL2=no to force SDL1
# - use OPTIMIZATIONS instead of ARCH for $SLKCFLAGS, upstream
#   changed the build a bit
# - undocumented VPX flag now defaults to "yes", since libvpx is a
#   core Slackware 14.2 package
# - slack-desc shows SDL version and whether or not libvpx was used.
