In a recent posting to bionet.software, Kay Hofmann expressed some
frustration with what he called "these unix-tar.Z archives" and asks
if there is a utility available to decode these files under VMS.
The files with a .Z suffix are not tar archives. They are merely
compressed, using the standard UNIX compress utility. None of the
filenames have "tar" in them; none of the readme.doc files
speaks of "tar".
The VMS executable, pub/vms/lzdcmp.exe, can be used under the
VMS operating system to uncompress the .Z files found in our
ftp archive area. It works for our users, although you must
be using one of the more current versions of VMS.
