The executable can be found in the /bin folder.
The Downloader takes two parameters, the first is the year that you wish to download, the second is the path to where you want to download the files.

NOTE: The tool is multithreaded, and will download an entire season in about 5 minutes. There's a chance that mlb.com will frown upon the speed of HTTP requests made and throttle/block your IP address, but this has not happened to me yet.
