This document describes the currently defined hooks.
This hook is invoked by `git-applypatch` script, which is
typically invoked by `git-applymbox`. It takes a single

The hook is allowed to edit the message file in place, and can
be used to normalize the message into some project standard
format (if the project has one). It can also be used to refuse
the commit after inspecting the message file.
