Monitoring Processes with Supervisord

This weeks SFH covers Supervisord (The eBook mentioned there will cover forever and Circus as well).

I've tried to add a little beyond the usual tutorial on Supervisord to include things like adding environmental variables your application can use, and setting up Supervisord's web interface.

Upstart and systemd are not that complicated. Supervisord certainly has advantages -- the main one is that it's always a `pip install` away on *nix platforms.

I've been using supervisord for a while, but never knew it had a built in webserver..
