===========
[Go](http://golang.org) package to calculate the [Levenshtein Distance](http://en.wikipedia.org/wiki/Levenshtein_distance)
The library is fully capable of working with non-ascii strings. But the strings are not normalized. That is left as a user-dependant use case. Please normalize the strings before passing it to the library if you have such a requirement.

Install
-------
go get github.com/agnivade/levenshtein
Example
-------
```go
package main
import (
"fmt"
"github.com/agnivade/levenshtein"
)
func main() {
s1 := "kitten"
s2 := "sitting"
distance := levenshtein.ComputeDistance(s1, s2)
fmt.Printf("The distance between %s and %s is %d.\n", s1, s2, distance)
// Output:
// The distance between kitten and sitting is 3.
}
```
