Fantastic. Thanks for the tutorial on profiling.

Will it be possible for you to use the change the file extension to rst and use some of the markup features of the rst format. For instance, `text` produces text, *text* produces italicized text, **text** for bold text. Create lists like so:

1. Something here
2. Next item

that produces --

1. Something here
2. Next item

or, for bulleted lists

-  Something here
-  Next item

• Something here
• Next item

Done after some fiddling around. It seemed that double inverted ` was needed at the beginning and end to get the monospaced text, is generated by ``text``.
