+used to find copy pasted blocks of code, or stuff that could be refactored.
+Differences concerning only stuff behind a '#' (Python comments) can be ignored.
+The size of identical blocks can be optionally modified.

+\'s functionality is integrated in

+
+.SH OPTIONS
+
+.IP "-h, --help"
+show help message and exit
+.IP "-d <min_duplicated_lines>, --duplicates <min_duplicated_lines>"
+minimum number of identical lines that should trigger a similarity message.
+Default is 4. So if it finds 3 identical lines, there will be no message, but
+4 identical lines will be mentionned.
+.IP "-i, --ignore-comments"
+ignore differences concerning only stuff behind a '#' (Python comments). This
+means that if just a comment was added, the message will still be triggered.
