  Description: evented I/O for V8 javascript
   Node.js is a platform built on Chrome's JavaScript runtime for easily
   building fast, scalable network applications. Node.js uses an
   event-driven, non-blocking I/O model that makes it lightweight and
   efficient, perfect for data-intensive real-time applications that run
   across distributed devices.
   .
   Node.js is bundled with several useful libraries to handle server
   tasks:
   .
   System, Events, Standard I/O, Modules, Timers, Child Processes, POSIX,
   HTTP, Multipart Parsing, TCP, DNS, Assert, Path, URL, Query Strings.
