+I use algorithm kindly provided by TheSpanishInquisition here: <http://jsperf.com/damerau-levenshtein-distance>.
+
+All credits goes there. I have only packed it into Node module.
+
+It provides a function that takes two string arguments and returns a hash like this:
+
+```` javascript
+{
+  steps: 5,       // Levenstein demerau distance
+  relative: 0.7,  // steps / length of the longer string
+  similarity: 0.3 // 1 - relative
+}
+````
+
+Please see [tests](./test/test.js) for more insights.
