svg output

[Joram Berger]

Hi,

could the lilypond options to specify the output file format be unified?
Currently, depending on the format, there are different options:

--pdf or --formats=pdf (and ps and png)
-dbackend=svg (eps, scm, …)

Even though things are perhaps a little bit different, I would suggest
to include svg (or the whole backend-options) into formats, if possible.
Because thats essentially what the user wants: get the output in the
format svg.

Cheers,
Joram
