# Build-Script for Midgard Packages
# ---------------------------------
# Author: Torben Nehmer, Linksystem Muenchen <t.nehmer@buero.link-m.de>
# $Id$
#
#
# This Script is used to export Midgard snippets from a Development 
#   Database and to create the distribution     Packages.
#
# SYNTAX:
#   build configfile command
#
# COMMANDS:
# xml: Builds the .xml.gz's.
# package: Builds midhoo-release.tar.gz 
# all: Launches xml, cvs and package per default, can be customized
#      in ALL_COMANDS
#
# cvs: Lauches a cvs commit after updateing the XML Files
# clean: Clean up the source tree including any package files.
#        This should leave only the cvs files.
#
# CVS support: The Makefile requires that cvs requires no argument
#       to access the repository. Ensure that the environment is 
#       correct.
#
# Naming conventions - for a package <package> these files will be used:
# <package>.xml is the XML File in the repository. Will be generated
#       out of the <package>.xml.gz export from repligard.
# <package>.conf is the Config File in the repository. This file has to
#       make repligard export the desired xml.gz File.
#
# The Package command uses the xml Files specified above and the 
#   files in OTHER_FILES to create a PACKAGE_NAME-VERSION.tar.bz2
#
# These Parameters are now all defined in the config file. See Example.
