It seems that Tigus tool aims for you to pass an ADT File (Map file, you know) to it and it will create you a wmo that includes all of them together.
So far the good Message. Now the bad one: I had a look at the source. I dont know any Phyton but what I saw so far this tool isn't rlly "done" right now. It seems that you have to change the input file AND the export files inside of the source-code ..

Line: 72
The whole thing looks more like leaked, not like an release .. But after changing those lines it might work. Dunno. I dont even have a python lib installed so I cannot test it.
