* This module is part of an effort to make the most important features
* of the IPv4 Socket layer available to Lua scripts.
* The Lua interface to TCP/IP follows the BSD TCP/IP API closely,
* trying to simplify all tasks involved in setting up a client connection
* and server connections.
* trying to simplify all tasks involved in setting up both client
* and server connections.
* The provided IO routines, send and receive, follow the Lua style, being
* very similar to the standard Lua read and write functions.
* The module implements both a BSD bind and a Winsock2 bind, and has
* been tested on several Unix flavors, as well as Windows 98 and NT.
