# This script creates an additional source in an existing tree to accomodate
# update packages without changing the original product tree.
# The script will only create the directory structure and the needed meta files.
#
# After running this script, you have to copy the packages into 
#
#		<source>/updates/suse/<arch>
#
# and run the script 
#
#	 	/usr/bin/create_package_descr -x setup/descr/EXTRA_PROV \
#
# in the data directory (<source>/updates/suse)
# after that do "cd setup/descr" and then:
# for i in *; do echo -n "META SHA1 "; sha1sum $i|awk '{ORS=""; print $1}'; echo -n " "; basename $i; done
# copy the output to the end of the updates/content file

# Uwe Gansert (uwe.gansert@suse.de)
#
# Version 20060925 (uwe.gansert@suse.de)
#   - replaced =~ by grep to be compatible to pre bash 3.0
#
# Version 20060420 (uwe.gansert@suse.de)
#   - suppress META SHA1 lines in the content file
#
# Version 20060418 (uwe.gansert@suse.de)
#   - added support for add-on products of SLES10/SL10.1
#
# Version 20051207 (uwe.gansert@suse.de)
#   - added missing $SOURCE for the copy of the EXTRA_PROV file
#     thanx to Ian Grant
