Slackware 13.1 x86_64 stable is released!
Lots of thanks are due -- see the RELEASE_NOTES and the rest of the
ChangeLog for credits.  The ISOs are on their way to replication,
a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We are taking pre-orders now at store.slackware.com, and offering
a discount if you sign up for a subscription.  Consider picking up
a copy to help support the project.  Thanks again to the Slackware
community for testing, contributing, and generally holding us to a
high level of quality.  :-)
Enjoy!

Usage: upgradepkg newpackage [newpackage2 ... ]
upgradepkg oldpackage%newpackage [oldpackage2%newpackage2 ... ]
Upgradepkg upgrades a Slackware package (.tgz, .tbz, .tlz, .txz) from an
older version to a newer one. It does this by INSTALLING the new package
onto the system, and then REMOVING any files from the old package that
aren't in the new package. If the old and new packages have the same
name, a single argument is all that is required. If the packages have
different names, supply the name of the old package followed by a percent
symbol (%), then the name of the new package. Do not add any extra
whitespace between pairs of old/new package names.
Before upgrading a package, save any configuration files (such as in /etc)
that you wish to keep. Sometimes these will be preserved, but it depends
on the package. If you want to force new versions of the config files
to be installed, remove the old ones manually prior to running upgradepkg.
To upgrade in a directory other than / (such as /mnt):
ROOT=/mnt upgradepkg package.tgz (or .tbz, .tlz, .txz)
