Run a process, streaming data in or out.

A lot of configuration options are available to fine-tune which inputs and outputs are streamed.

This uses streaming-with to handle resource management, and streaming-concurrency for handling both stdout and stderr together.

As such, code is typically run in a continuation-passing-style. You may wish to use the Streaming.Process.Lifted module if you have many of these nested.

The functions in this library will all throw ProcessExitedUnsuccessfully if the process/command itself fails.

If using this module, you will need to have:

ghc-options -threaded

in the executable section of your .cabal file, otherwise your code will likely hang!
