Detect Copy and Paste of Perl5 Codes

• my $detector = Compiler::Tools::CopyPasteDetector->new($options);

  Create new instance. You can create object from $options in hash reference.

• my $data = $detector->detect([$filename1, $filename2, ...]);

  Get raw detected data. This method requires filenames in array reference.

• my $score = $detector->get_score($data);

  Get scoring data of code clones. This method requires $data getting from $detector->detect.

• $detector->display($score);

  Output results of code clones to console. This method requires $score getting from $detector->get_score.

• $detector->gen_html($score);

  Output results of code clones to HTML. This method requires $score getting from $detector->get_score.
