HISTORY

Ndiff started as a project by Michael Pattrick during the 2008 Google Summer of Code. Michael designed the program and led the discussion of its output formats. He wrote versions of the program in Perl and C++, but the summer ended shortly after it was decided to rewrite the program in Python for the sake of Windows (and Zenmap) compatibility. This Python version was written by David Fifield.
