[Replicant] Automatization Replicant build

[Replicant]

Hi everybody,

I'm using the Replicant v6.0 on my Samsung S3 (I9300),
I think is not a "Official/Stable version" because I found in a thread 
on Replicant Forum.

I asked to myself:

1. What is necessary to a version of replicant be considered official?
2. Exist a tutorial describing all processes to build a replicant ?

Maybe we can create an automated process to build a replicant image.
Exist a tutorial describing all step to build a replicant image ?
