I've created a first draft while I get acquainted with the different
formats to submit a more compliant proposal, but I want to circulate this
draft for comments. I've only done three of the suggested headers and did
not add the output for the examples—didn't find a suggested way to do it.

I tried to look at all the different "spots" that would have to be touched,
but I may have missed something.

Much appreciated.
