libtext-wagnerfischer-perl binary package in Ubuntu Lunar amd64

 Text::WagnerFischer implements the Wagner-Fischer dynamic programming
 technique, used here to calculate the edit distance of two strings.
 The edit distance is a measure of the degree of proximity between two
 strings, based on "edits": the operations of substitutions, deletions
 or insertions needed to transform the string into the other one (and
 vice versa).
