$(basename $0 .sh) will completely set up a web site, including a domain
name and an apache configuration file.  The site will be acquired from a
git repository and configured.  At the end of this script, the result should 
be an almost working website; you may need to fix the site configuration,
create databases and so forth.

This script must be run as sudo or root; it makes changes to system files.
app name: The app name parameter is mandatory.  The configuration file for
this script will be derived from the app name (e.g. if the app name is MyApp,
then the config file will be 'MyApp.config').  The config files are by
convention stored in the 'config' directory.  The configuration file can be
overridden by setting the SITE_MANAGEMENT_CONFIG_FILE environment variable."
