yyeah go for it.  try not to go too overboard (a la jinja2) it's just
not worth it.  see how it goes: if there turns out to be a hell of a lot
of "if format == " statements then some sort of *really small* API would
be worth considering, i do tend to find however that the readability of
such APIs is absolutely awful and after about the 5th one you deeply
regret having created them, and go back to code-duplication, where at
least the damn code is linear, shorter, and bleedin obvious.

see how you get on.  this could be short enough to work out okay: it's
only 50 lines within the cvs.svp64.items() loop.

what might be handy would be to drop in some namedtuples. or perhaps
if i'd put in comment it would help, ehn?
