PrefVote is to promote ranked-choice preference voting algorithms. Updated with Condorcet voting algorithms, it's descended from the Vote::STV software written which I wrote in Perl originally in 1998 and used by multiple clubs and non-profit organizations over the years for polls and elections.

A toolkit for alternative voting methods. Initially to support Rankled and Range Ballots for IRV, Boorda, and Pairwise/Condorcet. Future support planned Multi-member methods.
