The git remote cache deployment task.

Browse Source 
This tasks uses a remote checkout on the server to provide the release.
In our use case this remote cache resides in $to/$shared/git-remote-cache,
variable 'shared' is substituted with "shared" by default. At this time, the
remote cache is not build automatically, you need to provide a clean
checkout before you can start using it.
