+# git-remote-branch 0.1 - 2008-01-25
+# by Carl Mercier (carl@carlmercier.com)
+#
+# This script allows you to easilly create and destroy local and remote 
+# branches at the same time.
+#
+# git-remote-branch create: creates a remote branch from the current branch, 
+#      creates a local tracking branch with the same name and switch to it 
+#      (ie: checkout).
+#
+# git-remote-branch delete: deletes the remote branch then deletes the local
+#      tracking branch.  It won't force a delete if there's pending changes
+#      in your local branch.
+#
