how and where to get information about samba 4 ?

[Manu]

Hi,

nobody reply on IRC, nobody replies here, so, where and how to get
information, documentation about samba 4 ?

Must we spend hours and hours and hours to discover things on our own?

Is Samba 4 a developer toy?
Will it be released when AD technology will be totally deprecated?

How to share knowledge?
Development advances?
Developers' needs?
Users' experiments?
Users' questions?

Any reaction?

Manu.
