Ticket #106: netlabs-rpmbuild-all.sh

#!/bin/sh

# This script takes a .spec file and performs a full rebuild of RPM packages
# for all acrhitectures supported by netlabs.org RPM repositories using the
# environment from the netlabs_rpmbuild_env.sh script (see that file for more
# information about the environment). It also generates a .zip package from
# the last listed architecture (usualliy i386).
