/* The list of shell builtins.  Each element is name, function, flags,
   long-doc, short-doc.  The long-doc field contains a pointer to an array
   of help lines.  The function takes a WORD_LIST *; the first word in the
   list is the first arg to the command.  The list has already had word
   expansion performed.

   Functions which need to look at only the simple commands (e.g.
   the enable_builtin ()), should ignore entries where
   (array[i].function == (sh_builtin_func_t *)NULL).  Such entries are for
   the list of shell reserved control structures, like `if' and `while'.
   The end of the list is denoted with a NULL name field. */

    OPTSTRING contains the option letters to be recognized; if a letter\n\
    is followed by a colon, the option is expected to have an argument,\n\
    which should be separated from it by white space.\n\
    \n\

    the index of the next argument to be processed into the shell\n\

    a shell script is invoked.  When an option requires an argument,\n\
    getopts places that argument into the shell variable OPTARG.\n\
    \n\
    getopts reports errors in one of two ways.  If the first character\n\
    of OPTSTRING is a colon, getopts uses silent error reporting.  In\n\
    this mode, no error messages are printed.  If an invalid option is\n\
    seen, getopts places the option character found into OPTARG.  If a\n\
    required argument is not found, getopts places a ':' into NAME and\n\
    sets OPTARG to the option character found.  If getopts is not in\n\
    silent mode, and an invalid option is seen, getopts places '?' into\n\
    NAME and unsets OPTARG.  If a required argument is not found, a '?'\n\
    is placed in NAME, OPTARG is unset, and a diagnostic message is\n\
    printed.\n\
    \n\
    If the shell variable OPTERR has the value 0, getopts disables the\n\
    printing of error messages, even if the first character of\n\
    OPTSTRING is not a colon.  OPTERR has the value 1 by default.\n\

      -O origin	Begin assigning to ARRAY at index ORIGIN.  The default index is 0\n\
      -s count	Discard the first COUNT lines read\n\
      -t	Remove a trailing DELIM from each line read (default newline)\n\
      -u fd	Read lines from file descriptor FD instead of the standard input\n\
      -C callback	Evaluate CALLBACK each time QUANTUM lines are read\n\
      -c quantum	Specify the number of lines read between each call to\n\
    			CALLBACK\n\
    \n\
    Arguments:\n\
      ARRAY	Array variable name to use for file data\n\
    \n\
    If -C is supplied without -c, the default quantum is 5000.  When\n\
    CALLBACK is evaluated, it is supplied the index of the next array\n\
    element to be assigned and the line to be assigned to that element\n\
    as additional arguments.\n\
    \n\
    If not supplied with an explicit origin, mapfile will clear ARRAY before\n\
    assigning to it.\n\
    \n\
    Exit Status:\n\
    Returns success unless an invalid option is given or ARRAY is readonly or\n\
