/**
 * <p>
 * The get_next application does a MIB tree walk, using the BlockPdu. 
 * It will start with the OID as configured in the properties file.
 * </p>
 *
 * <p>
 * It walks the tree by creating a new BlockPdu out off the
 * previous one. All information will be printed to
 * <code>System.out</code>.
 * </p>
 *
 * <p>
 * All parameters can be configured 
 * in the properties file. 
 * The name of the properties file can be passed as first argument to
 * this application. If there is no such argument, it will look for
 * <code>get_next.properties</code>. If this file does not exist, the
 * application will use default parameters.
