Hi,

I'm not sure if I entirely understand your question. Is "the model
builder" a person?

Making the assumption that it is (the usual term for this would be a
project maintainer) then you might wan to have a read of the
"DISTRIBUTED WORKFLOWS" section of the gitworkflows man page [1].

The short answer, if I've understood your question, is that all 3
developers will have to submit their work to the maintainer. There are
various mechanisms for this; they can either use "git format-patch"
and "git send-email" or request that the maintainer pulls from a
repository that they have published ("git request-pull" can help by
generating a nicely formatted email message).

After the maintainer has applied the changes the developers can then
use "git pull" to get the latest changes from the origin. This will
include their change and the changes from the other developers and may
also  include some merge commits.

As developers get more advanced they may start working on topic
branches and re-basing (or deleting) the branches after the maintainer
has applied their changes. Remember that in this case the topic
branches are local so the developers can do what they like with them.
The maintainer doesn't care _how_ the developers work locally they are
just concerned with the end result.

Hope that helps.
