Browse Source 
Add a note explaining that "addtask" can accept multiple dependencies,
just in case someone runs across such an example and is confused.

.. note::
While it's infrequent, it's possible to define multiple tasks as
dependencies when calling ``addtask``. For example, here's a snippet
from the OpenEmbedded class file ``package_tar.bbclass``::
addtask package_write_tar before do_build after do_packagedata do_package
Note how the ``package_write_tar`` task has to wait until both of
``do_packagedata`` and ``do_package`` complete.
