Hi Brooks,
I'm sorry, but I don't really like these pages that start with "in LaTeX, you would do this". The whole LaTeX example can be removed without changing the meaning of this page. I would be a happier if we do not use LaTeX references except in the "LaTeX to Context" section.
Is it ok if I remove the \newcommand example from this page (and possible others)?
(I'll extend it a bit at the same time :))
IP-based change was me --Taco
