147 This module implements the Levenshtein edit distance in a \s-1XS\s0 way.
148 .PP
149 The Levenshtein edit distance is a measure of the degree of proximity between two strings.
150 This distance is the number of substitutions, deletions or insertions (\*(L"edits\*(R")
151 needed to transform one string into the other one (and vice versa).
152 When two strings have distance 0, they are the same.
153 A good point to start is: <http://www.merriampark.com/ld.htm>
