DTS File Format

Hi!

Does anyone know where I can find the specification for the DTS model format?

I've searched everywhere, and although the TGB tell me how to export it from the various tools and use it with TGB, I can't seem to find out what the file format actually is. It doesn't seem to be in the TDN either, unless I've missed it somehow. :(

I'd really like to write an exporter of my own. Any tips from anyone where I might find the spec?

Thanks!!!!
