 * @brief  The main() function for the PTP daemon
 * 
 * This file contains very little code, as should be obvious,
 * and only serves to tie together the rest of the daemon.
 * All of the default options are set here, but command line
 * arguments are processed in the ptpdStartup() routine called
 * below.
