# A script to help manage the openSUSE:Tumbleweed project
# (C) 2010 Greg Kroah-Hartman <gregkh@suse.de>
# Released under the GPL v2.
#
# This script checks the links that are set up for a single Tumbleweed package.
# Tumbleweed works either by having packages submitted to it, or by linking to
# a "known stable" repository in the build service.  This script checks the
# repo and package name requested on the command line and verifies that they
# are up to date.  If they are not up to date, the proper 'osc' command is
# printed to output to be run by hand if necessary.
#
# If the package is not in the Tumbleweed repo, the proper 'osc' command
# to add it is printed out if you wish to run it.
#
# Any questions/comments/patches are gladly welcome, just send to:
#	Greg Kroah-Hartman <gregkh@suse.de>
