Hey folks,

I get the following error message when attempting to compile my book,
but it doesn't appear to say what file / line number is responsible. Is
there a way to turn on file / line error messages, akin to what one sees
with gcc?

$ context Source/Handbook.tex --result="Handbook.pdf" --purgeresult
