Ndiff compares two scans at a time. The first scan is called the A scan and the second scan is called the B scan.
Any other arguments are taken to be the names of Nmap XML output files. There must be exactly two. The first one listed is the A scan and the second is the B scan.

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.
