   main
      <programming> The name of the subroutine called by the
      run-time system (RTS) when it executes a C program.  The
      RTS passes the program's command-line arguments to main as a
      count and an array of pointers to strings.  If the main
      subroutine returns then the program exits.
      Java has inheritted the name "main" from C but in Java it's
      more complicated of course.  The main routine must have a
      signature of exactly
       public static void main(String [])
      And it must be inside a public class with the same name as the
      source file where it is defined.
