Save every object in scene as individual .blend files via python? There is an excellent example here: https://blender.stackexchange.com/a/63000/37272 which saves all objects as .fbx files, but how do I get the script to save to .blend files instead?

EDIT: This line exports the selected objects to fbx: bpy.ops.export_scene.fbx(filepath=exportName, use_selection=True) 

How does the command look for saving the selected objects to a .blend file?
Take a look at my add-on Splode. It can export individiual objects into individual blend files, and then link those blend files into the current file, replacing the existing objects. You should end up with the same scene, except that the objects are now linked from their respective blend file.
