usage: test-parse-options <options>

    -b, --boolean         get a boolean
    -4, --or4             bitwise-or boolean with ...0100

    -i, --integer <n>     get a integer
    -j <n>                get a integer, too
    --set23               set integer to 23
    -t <time>             get timestamp of <time>
    -L, --length <str>    get length of <str>

String options
    -s, --string <string>
                          get a string
    --string2 <str>       get another string
    --st <st>             get another string (pervert ordering)
    -o <str>              get another string
    --default-string      set string to default

Magic arguments
    --quux                means --quux

Standard options
    --abbrev[=<n>]        use <n> digits to display SHA-1s
    -v, --verbose         be verbose
    -n, --dry-run         dry run
    -q, --quiet           be quiet
