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