libghc-concurrent-output-dev 1.10.12-1build1 (armhf binary) in ubuntu hirsute

 Provides a simple interface for writing concurrent programs that
 need to output a lot of status messages to the console, or display
 multiple progress bars for different activities at the same time,
 or concurrently run external commands that output to the console.
 .
 Built on top of that is a way of defining multiple output regions,
 which are automatically laid out on the screen and can be individually
 updated. Can be used for progress displays etc.
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
