Right then, this could be a grey area, I am gonna bring this very post to the Mods attention straight away to clarify if it is allowed. Normally, downloading programmes from torrent sites and the like isn't allowed here, but in this case, that is the idea! If they deem it innapropriate and against the rules, then please delete this post.
Go to the VUZE page here:
http://www.vuze.com/search?q=bushcraft
There you have a list of all of the bushcraft programmes available. Hover over the programme you want to download and there will be a box to download it. Don't click on that, but look above and you will see a <More info> tag. Click on it and a new window opens. Again, you have a Download button, and then a torrent file above it. You want the torrent file and need a torrent programme to download it.
HTH
