I would like to use the stderr output and then use schemes regexp. I am
not sure how to use the scheme code within c. I think this is a
fascinating idea. Can you point me to an example? It think this will
also help me to improve importmidi functionality because then I don't
have to worry about doing things like checking to see if a new measure
needs to added and so on.
