 '''hooks for sending email push notifications
 
 This extension let you run hooks sending email notifications when
 changesets are being pushed, from the sending or receiving side.
 
 First, enable the extension as explained in :hg:`help extensions`, and
-register the hook you want to run. ``incoming`` and ``outgoing`` hooks
+register the hook you want to run. ``incoming`` and ``changegroup`` hooks
 are run by the changesets receiver while the ``outgoing`` one is for
 the sender::
 
   [hooks]
   # one email for each incoming changeset
   incoming.notify = python:hgext.notify.hook
   # one email for all incoming changesets
   changegroup.notify = python:hgext.notify.hook
 
   # one email for all outgoing changesets
   outgoing.notify = python:hgext.notify.hook
 
 Now the hooks are running, subscribers must be assigned to
 repositories. Use the ``[usersubs]`` section to map repositories to a
 given email or the ``[reposubs]`` section to map emails to a single
 repository::
 
   [usersubs]
   # key is subscriber email, value is a comma-separated list of glob
   # patterns
   user@host = pattern
 
   [reposubs]
   # key is glob pattern, value is a comma-separated list of subscriber
   # emails
   pattern = user@host
 
 Glob patterns are matched against absolute path to repository
 root. The subscriptions can be defined in their own file and
 referenced with::
 
   [notify]
   config = /path/to/subscriptionsfile
 
 Alternatively, they can be added to Mercurial configuration files by
 setting the previous entry to an empty value.
 
 At this point, notifications should be generated but will not be sent until you
 set the ``notify.test`` entry to ``False``.
 
 Notifications content can be tweaked with the following configuration entries:
 
 notify.test
   If ``True``, print messages to stdout instead of sending them. Default: True.
 
 notify.sources
   Space separated list of change sources. Notifications are sent only
   if it includes the incoming or outgoing changes source. Incoming
   sources can be ``serve`` for changes coming from http or ssh,
   ``pull`` for pulled changes, ``unbundle`` for changes added by
   :hg:`unbundle` or ``push`` for changes being pushed
   locally. Outgoing sources are the same except for ``unbundle`` which
   is replaced by ``bundle``. Default: serve.
 
 notify.strip
   Number of leading slashes to strip from url paths. By default, notifications
   references repositories with their absolute path. ``notify.strip`` let you
   turn them into relative paths. For example, ``notify.strip=3`` will change
   ``/long/path/repository`` into ``repository``. Default: 0.
 
 notify.domain
   If subscribers emails or the from email have no domain set, complete them
   with this value.
 
 notify.style
   Style file to use when formatting emails.
 
 notify.template
   Template to use when formatting emails.
 
 notify.incoming
   Template to use when run as incoming hook, override ``notify.template``.
 
 notify.outgoing
   Template to use when run as outgoing hook, override ``notify.template``.
 
 notify.changegroup
   Template to use when running as changegroup hook, override
   ``notify.template``.
 
 notify.maxdiff
   Maximum number of diff lines to include in notification email. Set to 0
   to disable the diff, -1 to include all of it. Default: 300.
 
 notify.maxsubject
   Maximum number of characters in emails subject line. Default: 67.
 
 notify.diffstat
   Set to True to include a diffstat before diff content. Default: True.
 
 notify.merge
   If True, send notifications for merge changesets. Default: True.
 
 notify.mbox
   If set, append mails to this mbox file instead of sending. Default: None.
 
 notify.fromauthor
   If set, use the first committer of the changegroup for the "From" field of
   the notification mail. If not set, take the user from the pushing repo.
   Default: False.
 
 If set, the following entries will also be used to customize the notifications:
 
 email.from
   Email ``From`` address to use if none can be found in generated email content.
 
 web.baseurl
   Root repository browsing URL to combine with repository paths when making
   references. See also ``notify.strip``.

   notify extension - hooks for sending email push notifications
   
   This extension let you run hooks sending email notifications when changesets
   are being pushed, from the sending or receiving side.

     changegroup.notify = python:hgext.notify.hook
   
     # one email for all outgoing changesets
     outgoing.notify = python:hgext.notify.hook
   
   Now the hooks are running, subscribers must be assigned to repositories. Use
   the "[usersubs]" section to map repositories to a given email or the
   "[reposubs]" section to map emails to a single repository:
   
     [usersubs]
     # key is subscriber email, value is a comma-separated list of glob
     # patterns
     user@host = pattern
   
     [reposubs]
     # key is glob pattern, value is a comma-separated list of subscriber
     # emails
     pattern = user@host
   
   Glob patterns are matched against absolute path to repository root. The
   subscriptions can be defined in their own file and referenced with:
   
     [notify]
     config = /path/to/subscriptionsfile
   
   Alternatively, they can be added to Mercurial configuration files by setting

   At this point, notifications should be generated but will not be sent until
   you set the "notify.test" entry to "False".
   
   Notifications content can be tweaked with the following configuration entries:
   
   notify.test
     If "True", print messages to stdout instead of sending them. Default: True.
   
   notify.sources
     Space separated list of change sources. Notifications are sent only if it
     includes the incoming or outgoing changes source. Incoming sources can be
     "serve" for changes coming from http or ssh, "pull" for pulled changes,
     "unbundle" for changes added by "hg unbundle" or "push" for changes being
     pushed locally. Outgoing sources are the same except for "unbundle" which is
     replaced by "bundle". Default: serve.
   
   notify.strip
     Number of leading slashes to strip from url paths. By default, notifications
     references repositories with their absolute path. "notify.strip" let you
     turn them into relative paths. For example, "notify.strip=3" will change
     "/long/path/repository" into "repository". Default: 0.
   
   notify.domain
     If subscribers emails or the from email have no domain set, complete them
     with this value.
   
   notify.style
     Style file to use when formatting emails.
   
   notify.template
     Template to use when formatting emails.
   
   notify.incoming
     Template to use when run as incoming hook, override "notify.template".
   
   notify.outgoing
     Template to use when run as outgoing hook, override "notify.template".
   
   notify.changegroup
     Template to use when running as changegroup hook, override
     "notify.template".
   
   notify.maxdiff
     Maximum number of diff lines to include in notification email. Set to 0 to
     disable the diff, -1 to include all of it. Default: 300.
   
   notify.maxsubject
     Maximum number of characters in emails subject line. Default: 67.
   
   notify.diffstat
     Set to True to include a diffstat before diff content. Default: True.
   
   notify.merge
     If True, send notifications for merge changesets. Default: True.
   
   notify.mbox
     If set, append mails to this mbox file instead of sending. Default: None.
   
   notify.fromauthor
