- * 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;
