This file packaged with InfoZip 5.x and contains a 32bit binary
that should run on any version of OS/2, 2.0 or later (although it
has only been tested on 4.0). It was built using EMX 0.9d and was
statically linked and, thus, does not require any additional libraries
to run.
Step 2: unpack.
NetHack is shipped in a single archive created with zip - unpack it
in an empty directory.
Step 3: install.
See the README unpacked in step 2 for additional instructions.
