The objsort program sorts through different obj files and arraigns the info to a more standard way that TDW's program didn't account for at the time.
I'll link the original example here.

Look at the included obj files in notepad or any text program and you'll see the issue objsort fixes.
(I forgot this file download was still active!)
Notice how things like v and vn along with f and vt are all sorts of messed up?
objsort reads the file, buffers all this then prints out a more common format.
No idea if this issue was ever fixed in TDW's program.
