+This is the source for the Roguelike Gallery's versions of Rogue and other
+early roguelike games.
+
+The code was obtained from the Roguelike Restoration Project
+(rogue.rogueforge.net).  Modifications have been made mainly for compatibility
+with the dgamelaunch online play system.  Some bugs have also been fixed, and
+the build process slightly improved.  The essential flavor of a codebase half
+as old as stored-program computing machinery remains unchanged.
+
+See the individual games' subdirectories for their documentation.
+
+The games can be played via SSH or the Web at rlgallery.org.
