+Update files on git push
+------------------------
+
+Using a post-receive hook the static files can be automatically updated.
+Keep in mind git push -f can change the history and the commits may need
+to be recreated. This is because stagit checks if a commit file already
+exists. It also has a cache (-c) option which can conflict with the new
+history. See stagit(1).
