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

# 20140827 bkw:
# - update for 0.7.0
# - require wxGTK3 (which is wx 3.x) instead of wxPython (wx 2.x)
# - pod-ify man page for easier editing
# - edit man page a bit
# - get rid of hard-coded /usr/share/games/doom, no longer needed
# - include sample orasrv.cfg from 0.6.4 source (it's gone from 0.7.0)
