"""simple Phabricator integration This extension provides a ``phabsend`` command which sends a stack of changesets to Phabricator, and a ``phabread`` command which prints a stack of revisions in a format suitable for :hg:`import`, and a ``phabupdate`` command to update statuses in batch. By default, Phabricator requires ``Test Plan`` which might prevent some changeset from being sent.
