I want to know if anyone can help me with git-credential-helpers we
are trying to use git-credential-helpers in the git-mediawiki
(implemented as a remote-helper).
We need to ask for the login/pass of the wiki and it would be nice 
if
we can use credential-helpers to manage this credentials.

Yeah, I think it makes sense to use the credential-helpers.

Anyone can send me a starting point, like a url with the
documentation of git-credential-helpers?

Try:



https://github.com/git/git/blob/master/Documentation/technical/api-credentials.txt

But that is the C API, and I assume you are building on the existing
mediawiki helper that is written in perl. So I think what you really
want is a "git credential" command that will let scripts hook into 
the
credential API. Something like:

  $ git credential get https://example.com
  username=bob
  password=secret

  $ cat <<\EOF | git credential store https://example.com
  username=bob
  password=secret
  EOF

  $ cat <<\EOF | git credential erase https://example.com
  username=bob
  password=secret
  EOF

I had planned eventually to do something like this for git-svn, but
realized that it was more sane to just let svn library handle the
credential storage.

Do you guys want to try writing "git credential" as above? It might 
be a
fun side project, but I know you are also on a limited timeframe for
your project. I can work on it if you don't have time.

Jeff thanks you for helping me with use credentials-helpers with 
git-remote
I will try to code your proposed solution.
making something like that:
