"""
panconfig.py - server-side configuration generator.

panconfig.py is pushed to the server and run by the deployment scripts to generate updated
configurations from the pushed domain content. Currently, this means getting static and wsgi
settings from each domain's project.yaml and generating Apache's httpd.conf to serve each
domain properly.
