annotation support?

[peng shao <shallpion gmail com>]

HI everybody, I just noticed that the newest evince 2.28 supports annotation on pdf files. I 
compiled it from source (since it is still unavailable) in my linux release)

But I do not know how to use this feature:( I tried to open a pdf file and did not find any menu option or something like that which indicates I can add annotation to my pdf.


Thanks

Peng
