    Mercurial has the ability to add new features through the use of
    extensions. Extensions may add new commands, add options to
    existing commands, change the default behavior of commands, or
    implement hooks.

    Extensions are not loaded by default for a variety of reasons:
    they can increase startup overhead; they may be meant for advanced
    usage only; they may provide potentially dangerous abilities (such
    as letting you destroy or modify history); they might not be ready
    for prime time; or they may alter some usual behaviors of stock
    Mercurial. It is thus up to the user to activate extensions as
    needed.

    To enable the "foo" extension, either shipped with Mercurial or in
    the Python search path, create an entry for it in your hgrc, like
    this::

      [extensions]
      foo =

    You may also specify the full path to an extension::

      [extensions]
      myfeature = ~/.hgext/myfeature.py

    To explicitly disable an extension enabled in an hgrc of broader
    scope, prepend its path with !::

      [extensions]
      # disabling extension bar residing in /path/to/extension/bar.py
      hgext.bar = !/path/to/extension/bar.py
      # ditto, but no path was supplied for extension baz
      hgext.baz = !
