heckesource.tar.gz
or as heckesource.tar
In the former case one first unzips with the UNIX command
gunzip heckesource.tar.gz
thus creating heckesource.tar
One unpacks heckesource.tar
with
the UNIX command
tar xvf heckesource.tar
This will create a directory hecke
(with contents) in your
current directory. If you are not on UNIX, you will have trouble with
these programs anyway. If you are on UNIX, but not on a SUN, you may
try standardized programs instead.
Or, if you want the latest, try
experimental programs instead.
