question about multiple parts

[Dave Phillips]

Greetings,

I'm writing another article about the state of music notation software 
on Linux, and I decided to score some of my older pieces as focus 
projects. I'm using the Frescobaldi program on Ubuntu 12.04, everything 
is going very nicely but I do have an important question.

I transcribed parts for a trio one by one, i.e. I scored the flute, 
bassoon, and guitar parts separately, and I'd now like to conjoin them 
into a single score. Is there a nice easy way to do that, maybe with 
something like #include files ? I'll be happy if someone can just point 
me in the right direction in the documentation (which I still find 
rather confusing, btw).

I also want to take a moment to thank everyone involved with LilyPond 
and its helpers. In my opinion LP is one of the finest projects in the 
free software world, an outstanding example of collaboration and 
contribution.

Best regards,

Dave Phillips
