/*
 *
 * Template for normal C programs. All the code was written with standard
 * tab settings, ie. every eighth column. Options are processed in routine
 * options() using getopt(). The non-option arguments are handled in
 * arguments(). To add a new option add its name to string *name and an
 * appropriate case to the switch in options() (see getopt in section 3
 * of the UNIX manual). You'll also need to add a bunch of code to handle
 * the non-option arguments.
