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> | |

156 All the credits go to Vladimir Levenshtein the author of the algorithm and to | |
