+[I] a sophisticated port of the original Doom game
+
+[T] Included is the freely distributable first episode of Doom:
+[T] "Knee-Deep in the Dead".
+[T] To play the entire game, you need to own a copy of Doom, Doom II,
+[T] Ultimate Doom or Final Doom.
+[T]
+[T] PrBoom is the culmination of years of work by various people and projects on
+[T] the Doom source code. PrBoom includes work from all of the following projects:
+[T]
+[T] Original Doom source release
+[T] Without id Software releasing the source code to Doom in the first place, we
+[T] couldn't be here. And one mustn't forget Bernd Kreimeier who prepared the
+[T] source for release.
+[T]
+[T] DosDoom
+[T] The first serious Doom port, got things working enough for other projects to
+[T] spawn from it. Also continued to provide a lot of innovative ideas for other ports.
+[T]
+[T] Boom
+[T] This project gave a complete overhaul to the Doom engine, one it badly needed.
+[T] All of Doom's infamous bugs and limitations were fixed. Many new features which
+[T] fitted nicely into the engine were added, including a better line types system,
+[T] translucency, friction and wind types, and much more.
+[T]
+[T] PrBoom
+[T] Brought Boom to Windows, and made large improvements to the graphics: first
+[T] higher resolutions, later OpenGL rendering.
+[T]
+[T] MBF
+[T] This continuation of the Boom project, by Lee Killough, did huge amounts of
+[T] debugging and other improvements, as well as adding more natural features in
+[T] the way that Boom had done. There were also some special features like Doom
+[T] beta emulation, and friendly monsters.
+[T]
+[T] LxDoom
+[T] Initially just a Linux port of Boom, it went on to become a portable POSIX Doom
+[T] port, with further compatibility improvements and debugging.
+[T]
+[T] lSDLDoom
+[T] This port of LxDoom to SDL brought the Windows and Linux development back
+[T] together. It just makes you wish we'd had SDL when the Doom source first
+[T] came out :-\.
