 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'.

 OSS - use OSS for audio? Default is "no", export OSS="yes" to enable.
   Most users won't need this.

 [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.
+     the .info file. I made it a hard dependency because the SDL user
+     interface has no real GUI features, while the gtkglext UI acts
+     like a proper GUI application. Users who just take the defaults
+     will end up with the usable UI. If you're reading this, you're
+     welcome to ignore the REQUIRES="gtkglext" and build with SDL2
+     only, if you have a reason to want to.
 
 [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,
