+ * str/hex - hex-to-string conversions and vice-versa
+ *
+ * This code contains simple routines for hexidecimal strings.

+ * Example:
+ *     int main(int argc, char *argv[])
+ *     {
+ *             int i;
+ *
+ *             for (i = 1; i < argc; i++) {
+ *                     char str[hex_str_size(strlen(argv[i]))];
+ *
+ *                     hex_encode(str, sizeof(str), argv[i], strlen(argv[i]));
+ *                     printf("%s ", str);
+ *             }
+ *             printf("\n");
+ *             return 0;
