ruby-levenshtein - 0.2.2-2+b12 main

The Levenshtein distance is a metric for measuring the amount of difference
between two sequences (i.e., the so called edit distance). The Levenshtein
distance between two sequences is given by the minimum number of operations
needed to transform one sequence into the other, where an operation is an
insertion, deletion, or substitution of a single element.
.
This Ruby library can work on strings, arrays or any other objects provided
the sequences respond to :each and the objects to :hash and :eql?.
