Create sorted list with number of directory elements in a directory 
tree. Useful to find directories with lots of files that need to be 
split up.

Usage: $progname [options]

Options:

  -h, --help
    Show this help.
  -q, --quiet
    Be more quiet. Can be repeated to increase silence.
  -s, --subtree
    Count files in whole subtrees instead of single directories.
  -v, --verbose
    Increase level of verbosity. Can be repeated.
  --version
    Print version information.
