* LuaSocket toolkit
* Networking support for the Lua language

*
* This library is part of an  effort to progressively increase the network
* connectivity  of  the Lua  language.  The  Lua interface  to  networking
* functions follows the Sockets API  closely, trying to simplify all tasks
* involved in setting up both  client and server connections. The provided
* IO routines, however, follow the Lua  style, being very similar  to the
* standard Lua read and write functions.
