Major changes from 1.2.3 to 1.2.4
* By default, do not restore file name and timestamp from those saved

gzip (GNU zip) is a compression utility designed to be a replacement
for 'compress'. Its main advantages over compress are much better
correctly. Try compiling gzip without any optimization if you have a
problem.

If you send me patches for machines I don't have access to, please test them
very carefully. gzip is used for backups, it must be extremely reliable.

GNU tar 1.11.2 has a -z option to invoke directly gzip, so you don't have to
patch it. The package ftp.uu.net:/languages/emacs-lisp/misc/jka-compr19.el.Z
also supports gzip'ed files.
The znew and gzexe shell scripts provided with gzip benefit from
(but do not require) the cpmod utility to transfer file attributes.

Some ftp servers can automatically make a tar.Z from a tar file. If
you are getting gzip for the first time, you can ask for a tar.Z file
avoid such a constraint.
On Unix, gzip is mostly useful in combination with tar. GNU tar

compresses better than zip, since gzip can then take advantage of
redundancy between distinct files. The drawback is that you must
scan the whole tar.gz file in order to extract a single file near

authors of these two programs work closely together in the info-zip
team. zip and unzip are not associated with the GNU project.
