[texworks] Beginners' needs (was: Lua scripting)

[Karl Berry]

    Probably a more generic document (mentionning latex, xelatex,
    context, maybe plain) would be an interesting addition for a future
    texworks "help links" menu.

FWIW, my attempt at a web page along these lines, sort of, is
http://tug.org/levels.html.

The lengthier documents that I know about, such as components-of-tex
(linked to on that page), are too old and/or too advanced to be
suitable.
