There may be a way to get Workspace and Installer.app to work on
a new kind of compressed file.  There is a program under development
called "gzip" (GNU zip) which is based heavily on the code in
Info-zip, but is designed to replace Unix compress, uncompress, and
zcat.  gzip can decompress normal Unix .Z files, as well as it's
own files.

Now, here's the tricky part.  There are executables in Installer.app
and /usr/lib/NextStep/Workspace.app/WM.app/compression.bundle that
I believe are used for decompression (they are fcat and compression)
but I don't know how they are used.  If someone from NeXT could tell
me (yo, NeXT, someone listening?), I can replace those with something
that understands both .Z files and gzip files (which can end in .Z
also if you like).

Then, you can use gzip to replace the current .Z files in both
packages and normal .tar.Z distributions with gzip compressed files.
The improvment in compression is quite significant.  That along with
another package (that uses a normal .Z file) that would replace the
decompression executables for Workspace and Installer.app would make
such files transparent to the user.
