Can we get the python code now?

I am quite interested in testing it with Meshfoot which uses Campbell Bartons OBJ import to load it's meshes into memory.

Is your code a drop in replacement?

Here is a snippet from the Meshfoot code:

import_obj.load_obj(localObjFullPathFileName, CLAMP_SIZE=
0.0, CREATE_FGONS= True, CREATE_SMOOTH_GROUPS= True, CREATE_EDGES=
False, SPLIT_OBJECTS= False, SPLIT_GROUPS= False, SPLIT_MATERIALS=
False, IMAGE_SEARCH=False)

Does your code leave the most recently imported object selected?
