# Now maintained by B. Watson.

# 20211102 bkw: someone else updated this for v2.3.1 BUILD=1.
# - BUILD=2.
# - new-style icons.
# - binaries in /usr/games.

# 20170207 bkw:
# - Take over maintenance, BUILD=2
# - Remove OpenAL and fmodapi from REQUIRES, since they are not
#   only not required, but actually not enabled in the build.
# - TODO: get rid of libpng sRGB profile warnings, especially in
#         doomsday-launcher where they cause a modal dialog.
# - TODO: get rid of "can't initialize FMOD" warnings, when fmodapi
#         isn't even built in.
# - TODO: install binaries to /usr/games, not /usr/bin
# - TODO: possibly have .desktop file start doomsday, not launch-doomsday,
#         since doomsday automagically locates the game resources instead
#         of forcing the user to manually navigate to the IWAD paths. Not
#         sure about this: what else does launch-doomsday do?
# - TODO: enable OpenAL and fmodapi as optional dependencies. Think this
#         is done in config_user.pri.
# - TODO: figure out how to decrease the detail level or something, so
#         the game runs faster than a slideshow on my system. Failing
#         that, do all of the above, then hand off maintenance to someone
#         who can afford a shinier newer video card than I can.
