  11usage: 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
  30String 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
  38Magic 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
  45Standard 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
