  11 usage: test-tool parse-options <options>
  12
  13     A helper function for the parse-options API.
  14
  15     --yes                 get a boolean
  16     -D, --no-doubt        begins with 'no-'
  17     -B, --no-fear         be brave
  18     -b, --boolean         increment by one
  19     -4, --or4             bitwise-or boolean with ...0100
  20     --neg-or4             same as --no-or4
  21
  22     -i, --integer <n>     get a integer
  23     -j <n>                get a integer, too
  24     -m, --magnitude <n>   get a magnitude
  25     --set23               set integer to 23
  26     -t <time>             get timestamp of <time>
  27     -L, --length <str>    get length of <str>
  28     -F, --file <file>     set file to <file>
  29
  30 String options
  31     -s, --string <string>
  32                           get a string
  33     --string2 <str>       get another string
  34     --st <st>             get another string (pervert ordering)
  35     -o <str>              get another string
  36     --list <str>          add str to list
  37
  38 Magic arguments
  39     --quux                means --quux
  40     -NUM                  set integer to NUM
  41     +                     same as -b
  42     --ambiguous           positive ambiguity
  43     --no-ambiguous        negative ambiguity
  44
  45 Standard options
  46     --abbrev[=<n>]        use <n> digits to display SHA-1s
  47     -v, --verbose         be verbose
  48     -n, --dry-run         dry run
  49     -q, --quiet           be quiet
  50     --expect <string>     expected output in the variable dump
