Readme

Output from parallel subprocesses is an ugly, many-headed beast. Piping though hydra-print provides an NCurses interface to a dynamic set output streams, displayed without interleaving. This is a common problem, for example, with parallel compiles, or data-processing scripts.

Specifically, this small library will split the screen when parallelism occurs, and unsplit it when the parallelism is finished (i.e. dynamically growing and losing "heads"). The io-streams library is used for all stream inputs.
