-i, <input_dir>, path to where to look for files. Only needed if current
dir is not used as input dir.
-o, <output_dir>, path to where to copy the found files. In case files with
same filenames are found, all copied files have a \"_<n>\" appended
incrementally to the prefix where n starts at 1.
-s, +|-<n>, file size in bytes; +n for greater then n; -n for less then n;
n for exactly n.
-p, \"<pattern>\", search file pattern as accepted by find's -name option; no
case distinction is made.
-h, usage and options (this help)
-l, see this script"
