[Bf-committers] Removing and using modules for importing .obj and exporting to .fbx

Hi, thanks for your reply. I have found the WM_operator functions which are
the functions such as "new file", "open file", "save" and a lot of other
But I cannot find any functions about the import and export which is weird
because they are on the same tab under file.
My goal is to write a .obj to .fbx converter. I know that the FBX export
might not be the best place to begin with but the importer for OBJ should
be around the same place.
I guess the converting part is not going to be easy either. Do you know
where that operation is located?
Thanks again for your answer
