Asio is a cross-platform C++ library for network and low-level
I/O programming that provides developers with a consistent asynchronous model
using a modern C++ approach.
Asio is also included in Boost but requires linking when used with
Boost. Standalone it can be used header-only provided a recent-enough
compiler.
