M2 is a tool to measure similarity of software code.
It is inspired from MOSS (http://moss.stanford.edu), but aims to provide much-required features such as bipartite matching of files instead of clique matching, support for newer languages, and a friendlier UI.
M2 is currently under development, and is not ready for production use. Interfaces currently defined are highly likely to change, and so are the command line options.
