aiofiles is an Apache2 licensed library, written in Python, for handling
local disk files in asyncio applications.

Ordinary local file IO is blocking, and cannot easily and portably made
asynchronous. This means doing file IO may interfere with asyncio
applications, which shouldn't block the executing thread. aiofiles helps with
this by introducing asynchronous versions of files that support delegating
operations to a separate thread pool.
