+/**
+ * Create branches for MediaWiki core and all Wikimedia-hosted
+ * extension repositories.
+ *
+ * Example for REL1_21:
+ *
+ * $ cd mediawiki/core
+ * $ git log --right-only --oneline gerrit/master...gerrit/REL1_21
+ *
+ * Get the last one and take note of the the commit hash.
+ * This commit is the first one that is in REl1_21 but not in master.
+ * Now get the CommitDate (not AuthorDate) of the parent of that commit, which
+ * is the last commit that is both in master and in the release branch.
+ * We can instruct git to access the parent by tacking "~1" to the hash:
+ *
+ * $ git show --format=fuller --quiet 4cb0dc1~1
+ * commit 49eacb3b3ae9cebdc7a407360454af3c1e33b3c9
+ * CommitDate: Sat Mar 16 12:00:59 2013 +0000
+ *
+ * @author Chad Horohoe, 2012
