"""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. The requirement could be disabled by changing
``differential.require-test-plan-field`` config server side.

select a stack.
``abandoned``, ``accepted``, ``closed``, ``needsreview``, ``needsrevision``
could be used to filter patches by status. For performance reason, they
only represent a subset of non-status selections and cannot be used alone.
For example, ``:D6+8-(2+D4)`` selects a stack up to D6, plus D8 and exclude
D2 and D4. ``:D9 & needsreview`` selects "Needs Review" revisions in a
stack up to D9.
If --stack is given, follow dependencies information and read all patches.
