* Self-Explanatory Protocol Buffer Lang Guide

/*
* Why Protocol Buffers?
* Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler.
* You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages.
* Protocol Buffers are Schema Of Messages. They are language agnostic.
