"""simple Phabricator integration (EXPERIMENTAL)
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.
A "phabstatus" view for :hg:`show` is also provided; it displays status
information of Phabricator differentials associated with unfinished
changesets.
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.
Config::

# callsign is "FOO".

# curl command to use. If not set (default), use builtin HTTP library to
# communicate. If set, use the specified curl command. This could be useful
# if you need to specify advanced options that is not easily supported by
