I haven't seen how he's packed this newest version but I have an older one that's all nicely placed in a folder called @SpyderAddons. You place that in your mod line and it should show up in the editor.

I haven't actually tried it myself yet but that is how it should work. You run this like any other mod (such as ALiVE).

Edit: I stand corrected. This must have been packed differently. Thanks Spyder.
