Hi there, this is a plagiarism plugin for Moodle 1.9.3.

It can detect plagiarism in C and Java language (.c, .h, .java, .zip files allowed into the upload's subimissions form). Zip files are automatically extracted and only C or Java files will be analyzed in the drawGraphs panel.

This plugin is supposed to work like in this way:
An exercise (.c file, .java file, and so on) is submitted via the uploadcode assignment plugin. Then, the admin (or who have the right permissions to view and analyze those exercises in that course) can have access to drawGraphs.php page, and can analyze those exercises via Global graphs, specific and comparison graphs functions.

This plugins uses the package similarity-tester written by Dick Grune (http://www.dickgrune.com/)
