# Script to generate distribution builds of LifeType
#
# (c) 27-08-2004, the LifeType Team
#
#
# Requires two parameters: the name of the output package and the
# CVS tag label that will be used to fetch the contents of the build. Therefore,
# contents must be tagged _before_ running this script. 
# The same CVS label must be used for both the plog_devel and plog_docs module.
#

#
# server and repository path
#
SVNSERVER=http://devel.lifetype.net
SVNREPO=/svn/plog/plog

#
# array with the files that we are going to remove before
# making the package... Wildcards, complete paths, whatever
# can be used here
# NOTE: When changing this list, update the list in build-diff.sh as well
