 %description
-This library provides an implementation of the older blaze-builder interface in
-terms of the new builder that shipped with bytestring-0.10.4.0
-
-This implementation is mostly intended as a bridge to the new builder, so that
-code that uses the old interface can interoperate with code that uses the new
-implementation. Note that no attempt has been made to preserve the old internal
-modules, so code that has these dependencies cannot use this interface.
-
-New code should, for the most part, use the new interface. However, this module
-does implement a chunked HTTP encoding, which is not otherwise implemented
-(yet?) with the new builder.
+This library provides an abstraction of buffered output of byte streams and
+several convenience functions to exploit it. For example, it allows to
+efficiently serialize Haskell values to lazy bytestrings with a large average
+chunk size. The large average chunk size allows to make good use of cache
+prefetching in later processing steps (e.g. compression) and reduces the system
+call overhead when writing the resulting lazy bytestring to a file or sending
+it over the network.
