You probably don't need to install anything, but that depends on how 
things are installed there.  I'd just try.

HTML Help Workshop is not available on Unix, but this probably isn't an 
issue:  if you're intending to use your package on Unix, you'll have no 
need for it.

Read the instructions for Unix, not for Windows.  In particular, don't 
touch the path unless your Unix sysadmin asks you to.

It depends on what you put in the files, but chances are they'll run 
with no changes.
