+This package provides slackware-upgrade-system, a script that performs
+a full upgrade of a Slackware distribution.
+Run "make install" as root. The slackware-upgrade-system will be
+installed to /sbin, and its man page, slackware-upgrade-system.8, to
+/usr/man/man8. These are most suitable locations for Slackware. To
+install them elsewhere, use the following Makefile variables:
+ SBINDIR - Directory to install slackware-upgrade-system to.
+ MANDIR - toplevel directory for man page installation (/usr/man).
+ MAN8DIR - directory for the man page installation ($(MANDIR)/man8).
+Before upgrade, please make sure you backup all sensitive data on your
+system. When upgrading a remote machine, it advisable to have a KVM
+console attached to it, so that you can intervene if the box refuses
+Please read slackware-upgrade-system(8) to familiarize yourself with
+the script and its options.
+Run slackware-upgrade-system in dry-run mode:
+ slackware-upgrade-system -n
+This will look for the nearest next release available, create the list
+of packages to be upgraded, installed and removed and will print the
+results. This run will not touch any files on your filesystem
+(excepting the slackware-upgrade-system logs, see below). Instead it
+will verbosely print what would have been done during real upgrade.
+Inspect its output to see if it actually does what you need. In
+particular, the upgrade will most likely decide to remove some
+packages during the upgrade. These are the packages that existed in
+your current release, but have been removed in the next one, or the
+packages you have installed from third-party sources. You may wish to
+retain any of them or provide replacements, or reinstall them afterward.
+If you wish to retain any of them, create a list of packages to retain
+and supply it to the script using the -k command line option (see the
+man page for details).
+To provide a replacement, use the -p option. For example, when
+upgrading from 14.1 to 14.2, the "procps" package will be removed. The
+utilities it used to provide have been moved to the "procps-ng"
+package. So, when upgrading from 14.1 to 14.2, it is a good idea to
+ slackware-upgrade-system -p procps-ng
+For your information, the list of removed packages is left in file
+/var/log/slackware-upgrade-system-<P>-<N>.removed (see below).
+When you are finished with the dry run, proceed to the actual upgrade.
+with any additional options you decided to give it after the dry run.
+After completion, the script will create three files for your
+consideration. In the discussion below, <P> stands for the original
+Slackware version number, and <N> stands for the new Slackware version
+number (the version you upgraded to):
+ Log file. Contains detailed transcript of all actions performed
+ during the upgrade.
+ A list of packages removed during the upgrade. A package is removed
+ if the new release does not provide a replacement for it. This may
+ not always be desirable, and you may reinstall some of them
+ A list of configuration file replacements created during the upgrade.
+ These are configuration files provided by the upgraded packages that
+ are left in the filesystem along with your current file versions.
+ They have the same names as the original files, but with the ".new"
+ suffix. Please revise these files. You may need to merge them with
+ your actual files, or move them over, or simply remove them.
+Before attempting to reboot your system, please make sure that the
+bootloader has been updated for the new kernel.
+We recommend to always upgrade to the next release, without skipping
+release numbers (even though the script allows you to do so). For
+example, instead of upgrading from 14.0 to 14.2, run two subsequent
+upgrades. First, upgrade your system, to 14.1 and make sure everything
+works as expected. Then, upgrade it to 14.2.
