libghc-concurrent-output-dev - 1.10.21-1 main

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.
