+Optional Dependencies
+=====================
+
+SDL2 - If this is installed, xroar's alternate "bare-bones" SDL2
+  user inteface will be available via the "-ui sdl" option.
+
+jack - if you want to use JACK for audio output, install jack and set
+  JACK=yes in the environment before building xroar. If JACK audio has
+  x-runs, try 'setcap cap_ipc_lock,cap_sys_nice=ep /usr/games/xroar'.
+
+
+Environment Variables
+=====================
+
+GTKGLEXT - If you have gtkglext installed, but don't want to build
+  xroar with it, export GTKGLEXT=no [1] [2].
+
+SDL2 - If you have SDL2 installed, but don't want to build xroar with
+ it, export SDL2=no [2].
+
+OSS - use OSS for audio? Default is "no", export OSS="yes" to enable.
+  Most users won't need this.
+
+PULSE - use PulseAudio? Default is "yes", export PULSE="no" to disable.
+
+
+Notes
+=====
+
+[1]: Yes, gtkglext is optional, despite being listed in REQUIRES in
+     the .info file. There's no "either-or" syntax for REQUIRES, so
+     I had to list either gtkglext or SDL2, and the gtkglext UI
+     is a lot nicer so it's what most people will want.
+
+[2]: At least one of SDL2 or gtkglext is required, so you can't build
+     with SDL2=no GTKGLEXT=no. If you want to be super-pedantic, yes,
+     it *is* possible to build xroar without either gtkglext or SDL2,
+     but the result is that xroar won't display anything at all. This
+     is useless and confusing, nobody wants it, and I'm not willing to
+     support it.
