Hi,
I noticed in fetdefs.tex:generalmeter{}{} that there was
provision for old-style mensuration marks, so I tried
altering the parser and time-signature code to enable
it... Now I get a tex file that won't work!
In \generalmeter{}{} definition there are calls to
\allabreve \threetwometer \fourfourmeter \sixfourmeter and
\ninefourmeter
These seem not to be defined anywhere?
(I *expect* \allabreve to generate a broken right-facing
circle with a vertical slash, \fourfourmeter to generate the
same without a slash `C', \threetwometer to generate a full
circle, \sixfourmeter to generate a broken circle with a centred dot
and \ninefourmeter to generate a full circle with a centred
dot.)
I can't find anything that looks plausibly like a definition
for these characters in the feta MF sources.
I'm willing to clean up and submit the changes I've made so
far, if a metafont expert can create the corresponding
characters and TeX definitions (or point me to where they are!)
