[Sabina Covarrubias]

Hello, I am new in Lilypond, because I need to include contemprary music notation in my socres, but I can not find 

any code or examples in the part concerning to Contemporary Music Notation: 

It is the same in the PDF version

http://lilypond.org/doc/v2.15/Documentation/notation/contemporary-music

Where can I find the examples in order to include contemporary graphics in my socres?

Is this aviable in Lilypond?

Thank you in advance.
