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.
