There is no download, as part of following Myrddraal's instructions in his long post above (using the code in the first post instead of that asked for in step 1) you will construct the files that you need.

However, as he says, this is a beta version - a taster for people who are already familiar with scripting. If you can't get it to work straight off the bat then you are in good company (myself included!) so you may have to wait until development can proceed a little further.
