Way overthinking this.

I want stub Markdown files for each (as yet undocumented) function.
The functions have docstrings but they are in ReST format.  Using the
`wrod.py` script I can fins all the functions that don't yet have doc
files and write their docstrings into a ReST template.  Then I use Make
and Pandoc to convert the ReST files to Markdown.
