Purchase Orders Dox Module (:mod:`tendril.dox.purchaseorder`)
=============================================================
This module provides functions to generate purchase orders.
The underlying assumption made in this module is that Purchase Orders are
relatively specific to vendors and include information that may be specific
to the materials being purchased. While this approach does need streamlining,
for the moment this works well enough to be functional.
.. todo:: Streamline the approach and the stage format.
The functions here use the :mod:`tendril.dox.render` module to actually
produce the output files after constructing the appropriate stage.
.. seealso:: :mod:`tendril.dox`
.. rubric:: Document Generators

Generates a purchase order using the template indicated by ``templateid``.
:param stage: The dictionary to be sent along to the jinja2 template.

:param templateid: The id of the template to use.
:type templateid: str
:param outpath: The path to which the output should be written,

.. rubric:: Template Used
This function uses a template specified by ``templateid``, specifically,
using the template named ``po_[templateid]_template.tex``.
.. rubric:: Stage Keys Provided
The contents of the ``stage`` provided to the jinja2 template are specific
to each template, and it is the responsibility of the caller to make sure
that it contains all the keys that the template expects. The parts of the
stage defined by this function, common to all templates, are :
.. list-table::
* - ``no``
- The serial number of the purchase order, either from the ``stage``
parameter or created.
* - ``point``
- The name of the contact person, defined by
:data:`tendril.utils.config.COMPANY_PO_POINT`.
* - ``date``
- The purchase order date, either from the ``stage`` parameter or
today's date.
* - ``lcofile``
- The latex lcofile to use, defined by
:data:`tendril.utils.config.COMPANY_PO_LCO_PATH`
