pipedream is a Python module intended to simplify launching and communicating with child processes over pipes. It provides a simple API based on cross-platform abstractions so the programmer does not need to manage launching child processes, opening and closing pipes, timeouts, or platform-specific peculiarities. It is especially useful for communicating with interactive programs which use stdin/stdout/stderr.
