+- `itertools` collection of iterators that are focused on processing (byte) streams of information collected from subprocesses. This includes basic support for simple pipe-like processing stream, including splitting off, and rejoining certain items in such a stream. These tools extend and interoperate with standard Python utilities for iterables, such as the built-in `itertools`, and the `more_itertools` package.
