The installation program was written by Olivier Montanuy
(author of DeuTex and DeuSF... two very fine Doom utilities) and
has been modified to work with Doom 2 by Jason Mezzacca. You'll
need about about 2.5 megs of extra disk space to install. The
installation will *not* change your doom2.wad nor will it change
doom2.exe so there will be no need to uninstall it to play Doom
normally again. The levels used for the normal A-TC game are map11
through map18, and map31 as the secret level. Map01 and map02 were
used for the two bonus levels. If there are any problems with the
installation, you can contact me at email@example.com.
Please, do not bother Justin or Olivier about it... if there's a
problem, it's most likely my fault.
