What is contacts.edb structure?

Windows Live Messenger creates a number of files like

C:\Users\USERNAME\AppData\Local\Microsoft\Windows Live Contacts{ae86acef-5a45-4447-bc开发者_高级运维32-521fc9289e1a}\DBStore\contacts.edb

and stores contacts within. When looking on such files, it is obviouos that they have strict structure. However, I failed to find the description of contacts.edb structure in internet.

Does anybody knows this structure? Or maybe there are some parser sources available? (I do not need a exe for that, I know about NirSoft one).

There is a project called libesedb which might be of use here. The contacts.edb file is an ESEBD file.
