# Script:	centos-rpmcheck
#
# Description:	Check installed RPMs against a list of official CentOS
#		RPMs and report mismatched or missing versions.
#		Used to verify a Fedora -> CentOS upgrade.
#		NB. Packages could be missing because they're not provided
#		by CentOS; you need to verify the output manually.
#		Close matches probably require forced update manually.
