    "description": "EventMachine implements a fast, single-threaded engine for arbitrary networkcommunications. It's extremely easy to use in Ruby. EventMachine wraps allinteractions with IP sockets, allowing programs to concentrate on theimplementation of network protocols. It can be used to create both networkservers and clients. To create a server or client, a Ruby program only needsto specify the IP address and port, and provide a Module that implements thecommunications protocol. Implementations of several standard network protocolsare provided with the package, primarily to serve as examples. The real goalof EventMachine is to enable programs to easily interface with other programsusing TCP/IP, especially if custom protocols are required.",
