  Step 2: unpack.

  
  NetHack is shipped in a single archive created with tar and then shrunk with gzip. To unpack under Unix, the following commands should be executed in an empty directory:

  	gzcat nethack-331.tgz > nethack-331.tar
  	tar xf nethack-331.tar
  

  The gzip package (containing gzip, gunzip, and gzcat) may be obtained from the Free Software Foundation. A version of tar is also available from the same site.

  Step 3: build.

  See the file README in the top level directory unpacked in Step 2 for build instructions for the various operating systems.
