+The code was designed to be modular: One module creates the command
+line interface (main.py), another implements the actions
+chosen in the CLI (cli.py), the MS COCO to SceneNet RGB-D mapping can

 Lastly, the SSD implementation from a third party repository
 has been modified to work inside a Python package architecture and
