  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:

        [extensions]

        foo =

      You may also specify the full path to an extension:

        [extensions]

        myfeature = ~/.hgext/myfeature.py

      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 needed.

      To explicitly disable an extension enabled in a configuration file of

      broader scope, prepend its path with !:

        [extensions]

        # disabling extension bar residing in /path/to/extension/bar.py

        bar = !/path/to/extension/bar.py

        # ditto, but no path was supplied for extension baz

        baz = !

      enabled extensions:

       children      command to display child changesets (DEPRECATED)

       rebase        command to move sets of revisions to a different ancestor

      disabled extensions:

       acl           hooks for controlling repository access

       blackbox      log repository events to a blackbox for debugging

       bugzilla      hooks for integrating with the Bugzilla bug tracker

       censor        erase file content at a given revision

       churn         command to display statistics about repository history

       clonebundles  advertise pre-generated bundles to seed clones

       closehead     close arbitrary heads without checking them out first

       convert       import revisions from foreign VCS repositories into

                     Mercurial

       eol           automatically manage newlines in repository files

       extdiff       command to allow external programs to compare revisions

       factotum      http authentication with factotum

       fastexport    export repositories as git fast-import stream
