When you clone the CML you get the repository with all of its history. There's a good chance that will be a one-way street - when the CML gets updated, you'll use GHfW to synchronize your copy with the GitHub repository. But you can also make changes to your own code, commit those changes to your local repository, and take advantage of Git's ability to merge the GitHub changes with your local repository commits. Of course if you do go down this route you'll want to build any needed binary files yourself.
Getting CML updates
Getting library updates is easy. Just run GHfW and bring up the CML repository. If there are pending updates the sync button will be enabled - click on it to bring your local copy up to date.
