"Protocol Buffers is a binary serialization format and technology, released to the open source community by Google in 2008.  Its primary use is to produce small fast binary representations of a 'message' or object for serialization or transportation.There are various implementations of Protocol Buffers in .NET. This project is a fairly close port of the Google Java implementation.There are two main parts:tools/protoc.exe, which takes the textual representation of the protocol buffer and turns it into a binary representation for use with ProtoGen.exe.tools/ProtoGen.exe, which takes binary representations of protocol buffer descriptors (as generated by the "stock" protoc binary supplied by Google) and creates C# source code. This is only required at build time.lib/*/Google.ProtocolBuffers.dll, which is a supporting library. This is required at execution time.lib/*/Google.ProtocolBuffers.Serialization.dll, a supplementary library that provides extensions for reading and writing protocol buffers to xml, json, and others.LINKS:Project Home    - http://code.google.com/p/protobuf-csharp-portOnline Help     - http://help.protobuffers.net/Developer Guide - http://code.google.com/apis/protocolbuffers/docs/overview.htmlLanguage Guide  - http://code.google.com/apis/protocolbuffers/docs/proto.html"
