- 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.
