Of course it is possible to do that. I thought it a good idea to use
separate calls, since when a file is processed at lilybin the result
is stored there and it could be useful to download it again without
having to process it anew.

Also, you can use lilybin -d remote-name.pdf local-path.pdf to rename
the downloaded file to something more convenient in one go.

Anyways, now you can use the -a flag to do both steps in one go.
