-The characteristics of this library is that different character encoding
-for every regular expression object can be specified.
+Oniguruma is a modern and flexible regular expressions library. It
+encompasses features from different regular expression implementations
+that traditionally exist in different languages. It comes close to
+being a complete superset of all regular expression features found
+in other regular expression implementations.
