  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

       color         colorize output from some commands

       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

       gpg           commands to sign and verify changesets

       hgk           browse the repository in a graphical way

       highlight     syntax highlighting for hgweb (requires Pygments)

       histedit      interactive history editing

       keyword       expand keywords in tracked files

       largefiles    track large binary files

       mq            manage a stack of patches

       notify        hooks for sending email push notifications

       pager         browse command output with an external pager

       patchbomb     command to send changesets as (a series of) patch emails

       purge         command to delete untracked files from the working

                     directory

       relink        recreates hardlinks between repository clones

       schemes       extend schemes with shortcuts to repository swarms

       share         share a common history between several working directories

       shelve        save and restore changes to the working directory

       strip         strip changesets and their descendants from history

       transplant    command to transplant changesets from another branch

       win32mbcs     allow the use of MBCS paths with problematic encodings

       zeroconf      discover and advertise repositories on the local network

Verify that extension keywords appear in help templates

  $ hg help --config extensions.transplant= templating|grep transplant > /dev/null
