+/*
+ * SDL implementation for Quake 3: Arena's GPL source release.
+ *
+ * I wrote such a beast originally for Loki's port of Heavy Metal: FAKK2,
+ * and then wrote it again for the Linux client of Medal of Honor: Allied
+ * Assault. Third time's a charm, so I'm rewriting this once more for the
+ * GPL release of Quake 3.
+ *
+ * Written by Ryan C. Gordon (icculus@icculus.org). Please refer to
+ * http://ioquake3.org/ for the latest version of this code.
+ *
+ * Patches and comments are welcome at the above address.
+ *
+ * I cut-and-pasted this from linux_glimp.c, and moved it to SDL line-by-line.
+ * There is probably some cruft that could be removed here.
+ *
+ * You should define USE_SDL=1 and then add this to the makefile.
+ * USE_SDL will disable the X11 target.
