/**
* A tool for Calimero showing features of the {@link PropertyClient} used for KNX
* property access.
*
* PropClient is a console based tool implementation for reading and writing KNX
* properties. It supports network access using a KNXnet/IP connection or FT1.2
* connection. To start the PropClient, invoke the main-method of this class.
* Take a look at the command line options to configure the tool with the desired
* communication settings.
*
* The main part of this tool implementation interacts with the PropertyClient interface,
* which offers high level access to KNX property information. It also shows creation of
* the {@link PropertyAdapter}, necessary for a property client to work. All queried
* property values, as well as occurring problems are written to System.out
* .
