Hm. Gnus screwed the quoting. Perhaps you should stick to ">" as
quoting character (and perhaps I should, too, if I only knew how to :)

Uhm, right. I just wanted to sketch the structure a bit...

I have made the experience that parsers get too comlicated too
quickly, and are really hard to debug, and the code generated by yacc
is not really that large. Automake has also nice lex/yacc support.

I think I'll try to come up with a simple grammar and then we can
discuss further...
