## Description

EventMachine is a reactor-pattern network framework for Ruby that provides an asynchronous I/O library for performing non-blocking network and file operations. It functions as a network server framework used to build scalable TCP and UDP servers and clients that process multiple simultaneous requests.

The framework implements a concurrency model that dispatches network events to registered handlers using a single-threaded event loop. This approach allows for the management of high-concurrency network connections without the overhead of multi-threaded programming.

The library covers the development of event-driven servers, asynchronous network clients, and network proxy implementations. It also provides capabilities for monitoring files and networks to trigger actions when specific events occur.
