 #
 # hook extension to email notifications to people when changesets are
 # committed to a repo they subscribe to.
 #
 # 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.
