 %global common_summary Streaming data processing library
 
-%global common_description Conduits are an approach to the streaming data problem. They are meant\
-as an alternative to enumerators/iterators, hoping to address the same\
-issues with different trade-offs based on real-world experience with\
-enumerators. For more information, see http://www.yesodweb.com/book/conduit.
+%global common_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.
