So \layout ... is something of that an \set isn't???

I couldn't imagine, that 
\set Score.skipBars = ##t
was a music expression, for me it seems to be a command concerning the layout...
Do you have a hint about what is what (no idea about „object_id_setting“ and
„output definition“)? 
In the docu-section 10.1 Input files and 10.1.1, 10.1.2 File structure I didn't
found out so much.

Thank you a lot!
