  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-'

  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>

  36    --list <str>          add str to list
  37
  38Magic arguments
  39    --quux                means --quux
  40    -NUM                  set integer to NUM
  41    +                     same as -b
