# 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:
# /usr/local/etc/build
# lists the sources for the different distributions
#
# the rest is controlled by environment variables
#
# build.sh uses sudo su. /etc/sudoers needs a line like:
# %users  ALL=(ALL)       NOPASSWD: /bin/su
# for automatic building
