+This is an automated email from the git hooks/post-receive script. It was
+generated because a ref change was pushed to the repository containing
+the project "UNNAMED PROJECT".

+      from  $old_commit_hash (commit)
+
+Those revisions listed above that are new to this repository have
+not appeared on any other notification email; so we list those
