r'''Constructs README, README.org files
The README files are generated by this script. They are made from:
- The main module docstring, with some org markup applied to the README.org, but
not to the README
- The docstrings from each API function in the module, with some org markup
applied to the README.org, but not to the README
- README.footer.org, copied verbatim
The main module name must be passed in as the first cmdline argument.
If we want to regenerate the figures linked in the README.org documentation,
