2 * Replacement implementation of getopt.
3 *
4 * This is a replacement implementation for getopt based on the my_getopt
5 * distribution by Benjamin Sittler.  Only the getopt interface is included,
6 * since remctl doesn't use GNU long options, and the code has been rearranged
7 * and reworked somewhat to fit with my coding style.
