Thanks very much for that. 
Yes, that seems to work fine. It reveals one bug - if you have a score
with a script attached it pops up a dialog. It should just save it with
script in this case, as the non-interactive flag has been set.
BTW It did not work at first for me, because my installed version was
rather old, and I think when I recently introduced the
open-the-last-opened-file feature I, more or less inadvertently, fixed a
long standing bug with opening files from the command line. I suspect
that was what was frustrating my efforts to get the thing working
before.
Can we include this script in the release somehow,  so that people can
update old files before the next release - perhaps just in the release
notes?
I have started on the audio-mixer and have Denemo playing a source .ogg
file while simultaneously playing the Denemo score that is the
transcription. I think we should release before I commit this to main.
Can you put a release candidate onto denemo.org? After we have given a
bit of time for downloading and building and testing this then, if all
is well, you could upload the identical file to ftp.gnu.org.
