int main ( int argc, char *argv[] )

//****************************************************************************80
//
//  Purpose:
//
//    MAIN is the main program for ARGS.
//
//  Discussion:
//
//    ARGS reports on the command line arguments.
//
//    On input, ARGC is the number of command line arguments (including the
//    program name itself), and ARGV is a pointer to an array of pointers, 
//    the null-terminated strings that constitute the command line arguments.
//
//    Thus, if we have invoked a program by:
//
//      fred 1 alpha 3.7
//
//    then on input
//
//      ARGC is 4, and 
//
//      ARGV --> ARGV(0) --> "fred"
//               ARGV(1) --> "1"
//               ARGV(2) --> "alpha"
//               ARGV(3) --> "3.7"
