**Math::Vec - Object-Oriented Vector Math Methods in Perl**

This module was adapted from Math::Vector, written by Wayne M. Syvinski. It uses most of the same algorithms, and currently preserves the same names as the original functions, though some aliases have been added to make the interface more natural (at...
