#  Automatically fetch and upgrade the latest rpm packages.
#  Run this from cron every night to stay up to date on patches.
#
#  This script runs rpmwatcher to get any new rpm updates, then
#  tries to install them.  It first tries to install packages
#  individually, but if any fail then it tries to install them 
#  all at once.
#
#  Any packages in the rpm working directory are "upgraded"
#  using rpm -U so you can also put rpm's in the directory by hand
#  and they will be installed automatically.
