 %description
-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.
+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.
