+PrBoom is a modern doom game engine or "doom-port" to play id Software's Doom,
+Doom II, Doom expansion packs and custom "iwads" or mods (It doesn't include
+the game itself). It aims to be the most stable Doom port with the highest
+compatibility to the major Doom versions.
+
+If you don't own any of the Doom games, get the shareware doom1.wad from
+http://www.libsdl.org/projects/doom/data/doom1.wad.zip, unzip it, and
+rename it to lowercase:  mv DOOM1.WAD doom1.wad
+Then copy doom1.wad to /usr/share/games/doom/
+
+If you have one or all of the main Doom data files from idSoftware -
+either doom.wad, doom2.wad, tnt.wad, or plutonia.wad from one of the
+commercial Doom games, copy them there too.
+
+Highly recommended to play the Doom background music:
+TiMidity++ with eawpats or freepats (all available at SlackBuilds.org)
+
+Suggested: Take a look at the docs, man pages, or visit BahdKo at
+http://www.doom2.net to learn how to watch demos, info, files, etc.
+A great help for newcomers. (You may need a proxy to visit this url)

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
