'''@app

This file is the acting web server.

@host, tells the OS (guest VM) to accept connections from all public IP
    addresses.

Note: both the handler, and logger has levels. If the level of the logger is
      higher than that of the handler, no messages will be handled by the
      corresponding handler.
