Now that looks very business-like.

Yes, you need comments. (Well, I do anyway.)

Could it perhaps be handled by optional parameters in Michael's new
table format? In the past, I've handled such parsing variability with
lex & yacc, and a suitable BNF grammar [1]. Using such tools makes it
easy for the parser to accommodate evolution of the table format over
time. But maybe Michael has it all wrapped up. (I'll figure out how to
use git, and take a peek at his branch. I'm not sure whether my
familiarity with CVS is a help or a hindrance. I know that was a pain
until I learnt to think its way.)
[1] A listed grammar also answers any user question along the lines of
"Is this legit syntax?"
