Sync submodules

[Em DauPhu <emdauphu@gmail.com>]

Hi,

I have hard times trying to understand submodules and superprojects
(also I'm knew to git).
Here we use Clearcase (yeay...) and I would like to use git on top of
it on my desktop.

There's a project stored in two clearcase vobs.
What I did is "git init", "git add ." and "git commit -m "initial
commit"" in both clearcase vobs.
I created then a directory (D:/myProject for example) and in this
directory I did "git init", "git submodule add Y:\myview\projA" and
"git submodule add Y:\myview\projB". And finally "git commit -m
"initial commit"".

It is working fine, I build it with hudson specify the "D:/myProject/.git"repo.

How should I update it now ?
I believe I have to do "git add ." or "git commit" in both vobs
corresponding to the first two repos when new dev are added there.

What should I do next ? I don't think an add or a commit is needed in
the superproject. I don't see any changes when building my project.

I hope it is clear enough.

Thank you.
