quattro is a collection of small and powerful components for advanced task control in asyncio applications.

Using quattro gives you:

• elegant context managers for deadlines and cancellation: fail_after, fail_at, move_on_after and move_on_at.
• a Deferrer class and defer function to help with indentation and resource cleanup, like in Go.
• a TaskGroup subclass with support for background tasks and concurrency limits.
• a safer gather implementation, with concurrency limits.

quattro is influenced by structured concurrency concepts from the Trio framework.
