libghc-io-streams-doc 1.4.1.0-1build1 (s390x binary) in ubuntu bionic

 The io-streams library contains simple and easy-to-use primitives for I/O
 using streams. Most users will want to import the top-level convenience
 module "System.IO.Streams", which re-exports most of the library.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
