* Install
Install in "development mode" so any change of the program is effective.

Note: For system wide (global) installation log in as root or use sudo for example.
For local (user) installation the local path must be in the PYTHONPATH environment variable.
Typically $HOME/.local/lib/pythonX.Y/site-packages
