Unfortunately that doesn't help, as this only allows to *add* margins.
I think it is only a wrapper using Ghostscript anyway, so there should 
be a direct solution. It's possible to specify the box to be cropped 
using Ghostscript, and it is possible to crop to the content, which is 
what LilyPond does (-dEPSCrop).

For the function I need it would be necessary to retrieve the document 
width and the content box of the original file and then crop it ignoring 
the left and right part of the bounding box.
However, so far I'm poking in the fog and haven't found the proper way 
to do it.
I need a way to compile a score with LilyPond so these informations are 
present in the resulting file (PDF or EPS) so I can read it either 
directly from the file or using some tools like pdfinfo or similar.

Any suggestions?
