#!/bin/sh
# Usage:
# ./update-source.sh
# env variables controlling behaviour
#  build_package=[0|1] - build package when new version is fetched
#  prep_package=[0|1] - check if package can be unpacked (implies build_package)
#  publish_packages=[0|1] - publish built packages in ~/public_html/$dist/$arch
#  quiet=[0|1] - discard stdout of process
