 *   operations; show help summary if asked; see getoptv and putoptv
 *   to understand command line parsing and help summary display; see
 *   plc.h for the definition of struct plc;
 *
 *   the command line accepts multiple MAC addresses and the program
 *   performs the specified operations on each address, in turn; the
 *   address order is significant but the option order is not; the
 *   default address is a local broadcast that causes all devices on
 *   the local H1 interface to respond but not those at the remote
 *   end of the powerline;
 *
 *   the default address is 00:B0:52:00:00:01; omitting the address
 *   will automatically address the local device; some options will
 *   cancel themselves if this makes no sense;
 *
 *   the default interface is eth1 because most people use eth0 as
 *   their principle network connection; you can specify another
 *   interface with -i or define environment string PLC to make
 *   that the default interface and save typing;
