So here are some tools you may require to retrieve the releases mentioned on this site. Unfortunately I don't have time to go into the use of each of these but Google will certainly be glad to help you should you seek a "guide".
µTorrent (Windows / Wine)
Transmission (Linux / OSX / *nix)
Vuze (Windows / Linux / Mac)
Hosting Site Downloads
These tools are for releases that link to hosting sites like but not limited to Rapidshare, Uploading, Megaupload etc. They greatly simplify the download process as opposed to clicking the links directly and waiting in line and repeating file after file. These tools automate all of that.
JDownloader (Windows / Linux / Other)
Tucan Manager (Linux / Windows / OSX)
Note: JDownloader has a definite compatibility advantage over Tucan (JDownloader supports more services).
