Apologies for resending -- I sent this a few hours ago but I don't see it
on gmane, or in the gnu.org archive either.

Actually the manual answers question #1 -- I should be able to use the
prologue header argument for that. And I can already do #2 (included just
to outline the desired behavior completely).

I haven't found anything in the manual explaining how to run a shell
command on the output file from LilyPond execution. That's really the
crucial one -- it makes no sense to embed an A4 sized image into a beamer
frame...
