I'm writing a plain text document with numbered sections or chapters and am wondering if emacs can help with numbering and re-numbering sections. And of course would be great if it could then generate a table of contents as well.

I have had a search on google and looked through the emacs wiki but did not come up with anything other than for latex stuff and possibly muse mode, but I would like to keep this as a plain text README style document.

Thanks for any help or suggestions.
