Hacking ZWSRT - Does anybody know how to actually use it?

[MarcusRaven]

Okay, so I found zwsrt, which claims to combine srt and ssd files in Capcom games to make files playable using in_cube (or now whatever it is). Does anybody know how to actually use it? I try putting everything I can in the same directory, like it says, and nothing appears to happen.

EDIT: Let me mention that I'm trying to use this to get playable files from Monster Hunter Tri, which the readme for it claims to be compatible with.
