* int main (int argc, char const * argv[]);
*
* parse command line, populate plc structure and perform selected
* 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;
