NAME

compare-code - find similar pieces of code (file based)

VERSION

version 0.006

SYNOPSIS

This program is developed in an education/school environment. It's purpose is to help detect similiarities in the code of IT projects, and therefore making assessments (more) fair.

The script compares files containing source code (or any plain text) to each other. The approach for comparison is simplistic: Whitespace and comments are removed, then the comparison is done using the Levenshtein algorithm. Future releases may bring more sophisticated techniques.

This program is written in the Perl Programming Language.

If you are unfamiliar with GNU/Linux you might want to read Windows.pod in the doc directory.
