   $ hg help notify
   notify extension - hooks for sending email push notifications
   
   This extension implements hooks to send email notifications when changesets
   are sent from or received by the local repository.
   
   First, enable the extension as explained in 'hg help extensions', and register
   the hook you want to run. "incoming" and "changegroup" hooks are run when
   changesets are received, while "outgoing" hooks are for changesets sent to
   another repository:
   
     [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
   
   This registers the hooks. To enable notification, subscribers must be assigned
   to repositories. The "[usersubs]" section maps multiple repositories to a
   given recipient. The "[reposubs]" section maps multiple recipients to a single
   repository:
   
     [usersubs]
     # key is subscriber email, value is a comma-separated list of repo patterns
     user@host = pattern
   
     [reposubs]
     # key is repo pattern, value is a comma-separated list of subscriber emails
     pattern = user@host
   
   A "pattern" is a "glob" matching the absolute path to a repository, optionally
   combined with a revset expression. A revset expression, if present, is
   separated from the glob by a hash. Example:
   
     [reposubs]
     */widgets#branch(release) = [e-mail]
   
   This sends to "[e-mail]" whenever a changeset on the "release"
   branch triggers a notification in any repository ending in "widgets".
   
   In order to place them under direct user management, "[usersubs]" and
   "[reposubs]" sections may be placed in a separate "hgrc" file and incorporated
   by reference:
   
     [notify]
     config = /path/to/subscriptionsfile
   
   Notifications will not be sent until the "notify.test" value is set to
   "False"; see below.
   
   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 activated only
     when a changeset's source is in this list. Sources may be:
   
     "serve"       changesets received via http or ssh
     "pull"        changesets received via "hg pull"
     "unbundle"    changesets received via "hg unbundle"
     "push"        changesets sent or received via "hg push"
     "bundle"      changesets sent via "hg unbundle"
   
     Default: serve.
   
   notify.strip
     Number of leading slashes to strip from url paths. By default, notifications
     reference repositories with their absolute path. "notify.strip" lets you
     turn them into relative paths. For example, "notify.strip=3" will change
     "/long/path/repository" into "repository". Default: 0.
   
   notify.domain
     Default email domain for sender or recipients with no explicit domain.
   
   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 an incoming hook, overriding "notify.template".
   
   notify.outgoing
     Template to use when run as an outgoing hook, overriding "notify.template".
   
   notify.changegroup
     Template to use when running as a changegroup hook, overriding
     "notify.template".
   
   notify.maxdiff
     Maximum number of diff lines to include in notification email. Set to 0 to
     disable the diff, or -1 to include all of it. Default: 300.
   
   notify.maxsubject
     Maximum number of characters in email's 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 committer of the first changeset in a 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 the generated email
     content.
   
   web.baseurl
     Root repository URL to combine with repository paths when making references.
     See also "notify.strip".
