DESCRIPTION
    options:
    -s, --sort-order    specify file with custom sort order. File must contain JSON data.
    -i, --input         must be directory name or file that needs to be sorted
    -o, --output        sort result file. Use output when input is not a directory name, otherwise output param ignored. If output filename does not exist, the file is created. Otherwise, the existing file is overwritten.

    --help, -help, -h, -? or no options will print this man.
