Microtonal music in LilyPond

[Petr Pařízek]

Hello again!

#1. In this part of the Notation Reference manual, there's apparently a 
subsection called "Microtonal notation" but it appears to be completely 
empty. Why is that?

#2. The Notation Reference manual says that LilyPond makes it possible to 
notate music in such a way that the microtonal adjustments show up in the 
MIDI output as pitch-bend messages. Where can I find some details about this 
specific kind of notation?

Thanks a lot in advance.

Petr
