"""
fabric-graphite is a fabric script to install Graphite, Nginx, uwsgi and all dependencies on a debian-based host.
Plus, for a limited time, statsd support!
To execute:
* Make sure you have fabric installed on your local host (e.g. pip install fabric)
* run `fab graphite_install -H root@{hostname}`
(hostname should be the name of a virtual server you're installing onto)
It might prompt you for the root password on the host you are trying to instal onto.
Best to execute this on a clean virtual machine running Debian 6 (Squeeze).
Also tested successfully on Ubuntu 12.04 VPS.
