Short version: stay away
Background: I wasn't so much concerned about plagiarism, as much as looking for pieces of duplicate content between files. This is marked as a demo, but I was unable to get it working. It just keeps complaining I have the wrong Java version (I don't).
Status: N/A. More or less a dead program. My various tricks to break open installers and even the program's own installer wouldn't work, and appears to have been dropped by the author website.
