Some additional repos to consider:
silverstripe-build — A standardised build of the SilverStripe framwork and Content Management System. Currently the 2.4 and master branches are tracked and updated reasonably frequently. 2.4 should be used for production stability and master for bleeding edge development. Tagged builds will be added as they become available.
PhingPyrus — Pyrus tasks for the Phing build management system.
realtime-notification — How to build realtime notification system
