Actually, I don't think this is what the OP wanted. A pdf file can have 
other files attached (which are not displayed) and even signed for 
authenticity. These files are not included as text, but the PDF viewer 
typically displays a message that other files are attached to the PDF 
file and can be extracted and stored on disk.

Attached is a sample file, created by pdftk (test.pdf is created by 
lilypond, and the test.ly file is attached to it, and everything is 
output as test_attached.pdf):
        pdftk test.pdf attach_files test.ly  output test_attached.pdf

If you open it in acroread (in okular the file name of the attached file 
seems messed up), you'll see that the test.ly file is attached to the 
pdf and can be opened from acroread. You'll probably need to look at the 
tab with the paper clip to list the attached files.

I don't know if ps2pdf supports attaching files to the resulting pdf 
files, though...

Cheers,
Reinhold


PS: While IMSLP.org does not allow upload of source files directly, it 
allows/encourages contributors to attach the source files to the output 
pdf file.
