Ungarble output from several threads or commands

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Lets multiple threads and external processes concurrently output to the console, without it getting all garbled up.

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 by concurrent threads. Can be used for progress displays etc.
