- * getopt() 
- * 
- * The getopt() function is a command line parser.  It returns the next 
- * option character in argv that matches an option character in opstring. 
- * 
- * The argv argument points to an array of argc+1 elements containing argc 
- * pointers to character strings followed by a null pointer. 
- * 
- * The opstring argument points to a string of option characters; if an 
- * option character is followed by a colon, the option is expected to have 
- * an argument that may or may not be separated from it by white space. 
- * The external variable optarg is set to point to the start of the option 
- * argument on return from getopt(). 
- * 
- * The getopt() function places in optind the argv index of the next argument 
- * to be processed.  The system initializes the external variable optind to 
- * 1 before the first call to getopt(). 
- * 
- * When all options have been processed (that is, up to the first nonoption 
- * argument), getopt() returns EOF.  The special option "--" may be used to 
- * delimit the end of the options; EOF will be returned, and "--" will be 
- * skipped. 
- * 
- * The getopt() function returns a question mark (?) when it encounters an 
- * option character not included in opstring.  This error message can be 
- * disabled by setting opterr to zero.  Otherwise, it returns the option 
- * character that was detected. 
- * 
- * If the special option "--" is detected, or all options have been 
- * processed, EOF is returned. 
- * 
- * Options are marked by either a minus sign (-) or a slash (/). 
- * 
- * No errors are defined.
