 notify extension - hook extension to email notifications on commits/pushes
 
 Subscriptions can be managed through hgrc. Default mode is to print
 messages to stdout, for testing and configuring.
 
 To use, configure notify extension and enable in hgrc like this:
 
    [extensions]
    hgext.notify =
 
    [hooks]
    # one email for each incoming changeset
    incoming.notify = python:hgext.notify.hook
    # batch emails when many changesets incoming at one time
    changegroup.notify = python:hgext.notify.hook
 
    [notify]
    # config items go in here
 
  config items:
 
  REQUIRED:
    config = /path/to/file # file containing subscriptions
 
  OPTIONAL:
    test = True            # print messages to stdout for testing
    strip = 3              # number of slashes to strip for url paths
    domain = example.com   # domain to use if committer missing domain
    style = ...            # style file to use when formatting email
    template = ...         # template to use when formatting email
    incoming = ...         # template to use when run as incoming hook
    changegroup = ...      # template when run as changegroup hook
    maxdiff = 300          # max lines of diffs to include (0=none, -1=all)
    maxsubject = 67        # truncate subject line longer than this
    diffstat = True        # add a diffstat before the diff content
    sources = serve        # notify if source of incoming changes in this list
                           # (serve == ssh or http, push, pull, bundle)
    [email]
    from = [e-mail]   # email address to send as if none given
    [web]
    baseurl = http://hgserver/... # root of hg web site for browsing commits
 
  notify config file has same format as regular hgrc. it has two
  sections so you can express subscriptions in whatever way is handier
  for you.
 
    [usersubs]
    # key is subscriber email, value is ","-separated list of glob patterns
    user@host = pattern
 
    [reposubs]
    # key is glob pattern, value is ","-separated list of subscriber emails
    pattern = user@host
 
  glob patterns are matched against path to repo root.
 
  if you like, you can put notify config file in repo that users can
  push changes to, they can manage their own subscriptions.
