[capi-sig] Keyword creation in a module function

[Robert Steckroth]

Well, turns out that while the keyword dictionary thing is complex, my
problem was elsewhere.
Is it possible that the documentation is wrong?

The capital "S" in the docs state this ->
 S (object) [PyObject *]
Same as O.
here http://docs.python.org/2/c-api/arg.html?highlight=keyword#Py_BuildValue
But "S" it has string checking properties as opposed to "O".

E.g.
"if ( ! PyArg_ParseTupleAndKeywords(args, kwds, "|OSllS"...    !=    "if (
! PyArg_ParseTupleAndKeywords(args, kwds, "|OOllO"...


Anyway, got my thing figured out :)
