# UPGRADE.sh - shell script to provide an automated upgrade of all installed
#              packages for which an upgrade has been retrieved.

# 2005-09-25 Sylvain Robitaille: Start thinking about doing this via a
#                                Makefile, actually ...
# 2009-11-15 Sylvain Robitaille: allow for 64-bit Slackware; allow also for
#                                *.txz packages,
# 2015-07-07 Sylvain Robitaille: loop around command-line arguments
#                                to permit patches for multiple
#                                distribution versions to be obtained
#                                in a single call to the script.
