Hi Alan,
I'm assuming you must not have Git installed from the question,
otherwise you would be using git clone as the site shows.
On the http://git.xilinx.com, it says the following,
Users without Git installed may create a tar file by using the snapshot
feature. Select the tree view of the repository (far right side) on this
page, then select snapshot (near the top) and a gziped tar file will be
created and downloaded.
Is this what you're looking for?
