+=item fixups
+
+If the "fixups" parameter is set, its command is run whenever a repository
+is checked out, or updated. This provides an easy way to do things
+like permissions fixups, or other tweaks to the repository content,

+=item pre_ and post_

+If a "pre_action" parameter is set, its command is run before mr performs the
+specified action. Similarly, "post_action" parameters are run after mr
+successfully performs the specified action. For example, "pre_commit" is
+run before committing; "post_update" is run after updating.
