Searching for mods (looking for mods for Tribes of the East).

Hey, I found a mod for Zoltan, but I can't figure out how to install it.
Here's where I found it:

(at the very bottom of the page).
Please help, how do I install it? And if possible, could you convert it to the h5u format like the other mods?
