As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) Python source code syntax highlighting (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file. See also the latest Fossies "Diffs" side-by-side code changes report for "dupwaste": 2.44_vs_2.46.

    4 # as reported by findup (pipe `findup --summary`to this).

    7 # --help prints the command usage.
    8 # --human calculates the output size in KB, MB, GB, or TB.
