title: How to use git to get just the latest revision of a project?
body: <p>I don't want to clone the full repository and I'm not going to be submitting patches. I do want to easily get new revisions in the future.</p>
  <p>I have tried using <code>git clone</code>, but this creates a copy of the entire repository (huge file size) and tracking changes makes the disk space even bigger (100mb of files now takes up over 2gb).</p>
  <p>Is this possible?</p>
