# 20140916 bkw: bump BUILD to 2.
# add man page.

# 20140827 bkw: version bump, reset BUILD to 1.
# oblige 6.10 is nice, but it *only* supports the Doom games, so I'll
# add an oblige-legacy4 build for the old version.

# 20140213 bkw: bump BUILD to 2.
# Makefile.unixy updated so it installs data/doom[12]_boss (thanks to Black
# Rider for the bug report). Also get rid of +x permissions on the data files
# in /usr/share.
