Jenkins template for continuous integration for Drupal Multi Site

We've been working on implementing continuous integration for our projects to improve code quality. In the process we've built a template which should make it easy to setup CI for new projects and want to share these with the community. Hopefully you'll find it useful!.

These are for multi site but you can figure ont how it use it for a single site.

Requirements

PHP

Using the template requires a phing PEAR packages present. They can be installed as follows:

pear channel-discover pear.phing.info
pear install phing/phing-2.4.12

Jenkins
