  14     A helper function for the parse-options API.
  15
  16     --[no-]yes            get a boolean
  17     -D, --no-doubt        begins with 'no-'
  18     --doubt               opposite of --no-doubt
  19     -B, --no-fear         be brave
  20     -b, --[no-]boolean    increment by one
  21     -4, --[no-]or4        bitwise-or boolean with ...0100
  22     --[no-]neg-or4        same as --no-or4
  23
  24     -i, --[no-]integer <n>
  25                           get a integer
  26     -j <n>                get a integer, too
  27     -m, --magnitude <n>   get a magnitude
  28     --[no-]set23          set integer to 23
  29     --mode1               set integer to 1 (cmdmode option)
  30     --mode2               set integer to 2 (cmdmode option)
  31     --[no-]mode34 (3|4)   set integer to 3 or 4 (cmdmode option)
  32     -L, --[no-]length <str>
  33                           get length of <str>

  35                           set file to <file>
  36
  37 String options
  38     -s, --[no-]string <string>
  39                           get a string
  40     --[no-]string2 <str>  get another string
  41     --[no-]st <st>        get another string (pervert ordering)

  43     --longhelp            help text of this entry
  44                           spans multiple lines
  45     --[no-]list <str>     add str to list
  46
  47 Magic arguments
  48     -NUM                  set integer to NUM
  49     +                     same as -b
  50     --ambiguous           positive ambiguity
  51     --no-ambiguous        negative ambiguity
  52
  53 Standard options
  54     --[no-]abbrev[=<n>]   use <n> digits to display object names
  55     -v, --[no-]verbose    be verbose
  56     -n, --[no-]dry-run    dry run
  57     -q, --[no-]quiet      be quiet
