NAME

       Text::LevenshteinXS - An XS implementation of the Levenshtein edit distance

SYNOPSIS

        use Text::LevenshteinXS qw(distance);

        print distance("foo","four");
        # prints "2"

        print distance("foo","bar");
        # prints "3"

DESCRIPTION

       This module implements the Levenshtein edit distance in a XS way.

       The Levenshtein edit distance is a measure of the degree of proximity between two strings.  This distance
       is the number of substitutions, deletions or insertions ("edits") needed to transform one string into the
       other one (and vice versa).  When two strings have distance 0, they are the same.  A good point to start
       is: <http://www.merriampark.com/ld.htm>

       All the credits go to Vladimir Levenshtein the author of the algorithm and to Lorenzo Seidenari who made
       the C implementation <http://www.merriampark.com/ldc.htm>
