My plans for Weekend 27-28 and Sept 2-3

[rocky]

This weekend I will try to finish Curl in the dev guide, and do some cleanup on PRs from the week.

There was this parser extension that was needed for CellsToTeX, but I don't remember what that was. I looked for it in issues but I can't find it. If I find that, I'll work on that next week. Failing that, getting the mathics scanner information into mathics-core.
