It supports ps, eps, svg, pdf output. In the case of eps and svg, it
renames the (first!) sequentially numbered output file to the given
babel argument -- there might well be a better way of handling that
case, but it doesn't happen to me much because the music is one page
long most of the time.

Pretty sure there is already an FSF copyright assignment for me on
file.

Happy hacking,
