+	  OpenTyrian is a port of the DOS shoot-em-up Tyrian. It uses SDL,
+	  making it easily cross-platform.
+	  It requires the original data files to run.
+	  A display with minimum 640x480 resolution and a keyboard are needed
+	  to play the game.
+	  If you want some sound, activate ALSA with OSS emulation.
