I would
love to see that too. I would say its enough to agree on the conventions
(format and place in filesystem) and add them as a comment to the ladspa header.
Ah, but that's a big, hairy, controversial "enough",
unfortunately.
Some will swear for RDF turtle, some will kill in the name of a xml
dialect and some will argue the merits of no-nonsense ini files.
So far no one has. If we want to get this going it should be simples as the
rest
of ladspa. I think the format I proposed is so simple that one can parse/write
it without pulling additional dependencies into projects (see the attached example).
