#
# builds RPM in an clean chroot build environment.
# uses the Suse build script.
#
# without parameter, it checks the directory for the files
# SOURCES or SPECSOURCES. 
# The files definied in there are copied to the 
# build system.
# 
# when used with parameter, 
# this parameter is expected to be a source rpm
#
# config file:
# /etc/dassbuild.conf
# lists the sources for the different distributions
#
# the rest is controlled by environment variables
#
# dassbuild.sh uses sudo. /etc/sudoers needs a line like:
# %users  ALL=(ALL)       NOPASSWD: /usr/bin/dassbuild_wrapper.sh
# for automatic building (create a symlink or copy the file,
# see also the Variable BUILDSCRIPT and content of this script)
#
# return codes:
# 0: success
# 1: skipped (current RPM already in dest dir)
# >1: error
#
# RPM releases are set 
# to the svn version number of the project directory.
# Modifiers are:
#   m: release + local modifications
#   p: release + submited modifications. svn update project directory is needed 


# set LANG to default (english)
# required for SVN
