# 20170706 bkw:
# - fix build on -current

# 20151126 bkw:
# - fix build on systems that have SDL2 but not SDL2_ttf
# - add SDL2 environment variable
# - move binaries to /usr/games

# 20140826 bkw:
# - took over maintenance
# - update for 2.5
# - get rid of --enable-profiling, all it seems to do is leave a
#   gmon.out file in the dir where the game was run
# - allow disabling sse with environment variable
# - allow building the radiant editor. I have no idea if it's working
#   correctly, since I have no idea how to use it.
