Git

GIT (http://git-scm.com/) is a free and open source version control package that can be used to manage upgrades in Moodle. As an administrator adds third party plugins, frequent upgrades can break the operation of those plugins. GIT can assist in making those upgrades less unpredictable. At the recent iMoot 2010 conference, GIT was recommended by a Moodle Partner for Moodle site administration.
