 Name:                conduit
-Version:             1.0.9.2
+Version:             1.0.9.3
 Synopsis:            Streaming data processing library.
 Description:
     @conduit@ is a solution to the streaming data problem, allowing for production, transformation, and consumption of streams of data in constant memory. It is an alternative to lazy I\/O which guarantees deterministic resource handling, and fits in the same general solution space as @enumerator@\/@iteratee@ and @pipes@.
