process-streaming

Exploring how to interact with system processes using a streaming library (pipes).

The basic goals:

• Concurrent, streaming access to stdin, stdout and stderr.

• Easy integration with regular consumers, parsers from pipes-parse and various folds.

• Avoid launching exceptions: use Either or similar solution to signal non-IO related error conditions.
