1 The "String::Similarity" calculates the similarity index of its two
2 arguments. A value of '0' means that the strings are entirely
3 different. A value of '1' means that the strings are identical.
4 Everything else lies between 0 and 1 and describes the amount of
5 similarity between the strings.
