Using Additional Features

    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.
    To enable the "foo" extension, either shipped with Mercurial or in the
    Python search path, create an entry for it in your configuration file,
    like this::
      foo =
    You may also specify the full path to an extension::
      myfeature = ~/.hgext/
    See :hg:`help config` for more information on configuration files.
    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
    To explicitly disable an extension enabled in a configuration file of
    broader scope, prepend its path with !::
      # disabling extension bar residing in /path/to/extension/
      bar = !/path/to/extension/
      # ditto, but no path was supplied for extension baz
      baz = !
