#! /bin/sh
#
# check_package.sh -- test consistency of the owncloud server package
#
# The top part is owncloud specific apps handling.
# The remainder should be generic consistency test.
# 
# 2015-01-19, jw@owncloud.com, intial draught with automattic apps splitting.
# 2015-01-26, jw@owncloud.com, added generic debian.* vs *.spec checks.
# 2015-04-21, jw@owncloud.com, added dependency test. Easy to fool but better than nothing.
# 2015-05-13, jw@owncloud.com, handle critical=all and ignore owncloud-server-scl-php54 for debian.
# 2015-08-05, jw@owncloud.com, merged apps back into owncloud-server. This obsoletes most of this script.
