+		       Roguelike Gallery (rlgallery.org)
+
+This is the source code for the Roguelike Gallery's version of Rogue V3.
+
+History
+Rogue 3 was released by Michael Toy, Ken Arnold, and Glenn Wichman, probably 
+late in 1980.  It went through several minor updates.  The last, Rogue 3.6, 
+was completed mid-June 1981.
+
+The Roguelike Restoration Project (rogue.rogueforge.net) updated the game to 
+work on modern systems.
+
+The Roguelike Gallery's version has been slightly modified for compatibility 
+with dgamelaunch and security for multiple players.
+
+Installing
+First, configure for your system by editing machdep.h.  The defaults are for a 
+system-wide installation, which will require setgid on the binary.  For a 
+single-user installation, comment out SAVEDIR and set SCOREFILE and LOGFILE to 
+locations somewhere in your home directory.  (That's probably the best thing to 
+do on Windows, too.)
+
+Once that's finished, compile by running make.  (I haven't tested the Visual 
+Studio project files on Windows, but they should work.)
+
+If you want multi-user play, install the rogue3 binary with setgid games.  You 
+will need to make sure that SAVEDIR exists and that savefiles, SCOREFILE, and 
+LOGFILE can be created and written by the games group (assuming you want those 
+features.)  For a single user, installing shouldn't be necessary.
+
+Playing
+For more details, see readme36.html (contains the man page) and rogue36.html 
+(Michael Toy's "Guide to the Dungeons of Doom").
