&quot;&quot;&quot;
Script which takes one or more file paths and reports on their detected
encodings

Example::

    % chardetect somefile someotherfile
    somefile: windows-1252 with confidence 0.5
    someotherfile: ascii with confidence 1.0

If no paths are provided, it takes its input from stdin.
