gzip_package v2.7, March 1998, by Tom Hageman <tom@basil.icce.rug.nl>

Gzip_package tries to reduce the size of NEXTSTEP Installer packages.
It achieves this by replacing the package's contents archive, which is
compressed using compress(1), with a gzip(1)ped version of the archive.
Since Installer expects a compress(1)ed contents archive at installation
time, gzip_package also installs special pre_ and post_install scripts
to automatically convert the contents archive back to its original
compressed form before actual installation.  (If the original package
contained pre_ and post_install scripts, these will still be executed,
of course.)

INSTALLATION

Type "make install".  This installs gzip_package and gunzip_package (as
a hard link to gzip_package) in /usr/local/bin, and the manual pages in
/usr/local/man/man1.  If you want to install the distribution somewhere
else than /usr/local, you can override the make variable "prefix", e.g.
with the command "make prefix=/foo/bar install".
The directories ${prefix}/bin and ${prefix}/man/man1 are created if they
do not yet exist prior to installation.

HISTORY

v2.7, March 1998
 - fix bug that prevented pre_install script to funzip on (NeXT)
   systems without gunzip.

v2.6, November 1997
 - Avoid spurious warnings from post_install script when invoked from
   outside Installer.app.

v2.5, December 1996
 - Preserve permissions of files and directories inside package.  Force
   removal of backups, even if it contains readonly subdirectories.
   (gnutar still changes permission of readonly directories to
    user-writeable though.  Not much to be done about that...)
 - --unzip now removes gzip_package-specific *.pre_ *.and post_install
   scripts from the package.

v2.4, November 1996 (not released)
 - Fixed yet another NFS-mount related bug.

v2.3, February 1996
 - Avoid pre_install corruption when GNU sed v?.?? is installed.
   [as reported by Gregor Hoffleit <flight@mathi.uni-heidelberg.de>]

v2.2, December 1995 (not released)
 - Added -i, --info option.
 - Fixed bug that crashed gzip_package when the package it worked on
   was located on an NFS-mounted volume.

v2.1, July 1995
 - Allow multiple *.pkg arguments.
 - Improved error detection in installed *.pre_ and *.post_install scripts.
 - Fix non-serious bug in package expansion message.

v1.7, March 1995
 - First public release.
