The file nh313pc.exe contains NetHack 3.1.3 for Msdos, the current
version of the game. It is placed here only for convenience, and
because I hope this will soon become an "old" version as well.   :-)

The file is a self-extracting archive. Download it only if your PC is a
286 or older: otherwise, get the file nh313386.exe.

Release date: July 19th, 1993.
