+DOOM Retro is the classic, refined DOOM source port. It represents what DOOM
+should be today, in all its dark, gritty, unapologetically pixellated glory.
+DOOM Retro's source code is forked from Chocolate DOOM, with enhancements from
+other DOOM source ports, as well as many orignal ideas. DOOM Retro is
+deliberately minimalist by design, and does a few things differently when
+compared with other source ports.
+
+For MIDI playback, first build and install FluidSynth, then build and install
+SDL_mixer (so that it has FluidSynth support), and then build and install DOOM
+Retro. Then, before starting DOOM Retro, set the SDL_SOUNDFONTS environment
+variable to the path to a soundfont in sf2 format.
+
+i.e.
+
+  export SDL_SOUNDFONTS=/path/to/soundfonts.sf2
+
+Settings are stored in $HOME/.config/doomretro. You will find an editable
+doomretro.cfg there.
+
+There is a bonus episode, "breach", in /usr/share/doomretro/breach.

+# 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 ':' except on otherwise blank lines.
