libghc-blaze-builder-dev 0.4.1.0-4build2 (s390x binary) in ubuntu hirsute

 This library provides an abstraction of buffered output of byte streams and
 several convenience functions to exploit it. For example, it allows one to
 efficiently serialize Haskell values to lazy bytestrings with a large average
 chunk size. The large average chunk size allows one 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 package provides a library for the Haskell programming language.
