The default build configuration will build all branches specified in a text file on the server. Most of the time this will only be HEAD, but occasionally the developers may have an interest in building some experimental code on a different branch. The above configuration will do all of it automatically for you. The *run_cron* will also check the master repo at of the Exim Build Farm Client Software and update itself.
