+MessagePack for C/C++
+=====================
+Binary-based efficient object serialization library.
+
+
+## Installation
+
+Download latest package from [releases of MessagePack](http://sourceforge.net/projects/msgpack/files/) and extract it.
+
+On UNIX-like platform, run ./configure && make && sudo make install:
+
+    $ ./configure
+    $ make
+    $ sudo make install
+
+On Windows, open msgpack_vc8.vcproj file and build it using batch build. DLLs are built on lib folder, and the headers are built on include folder.
+
+To use the library in your program, include msgpack.hpp header and link msgpack and msgpackc library.
+
+
+## Example
+
+    #include <msgpack.hpp>
+    #include <vector>
+    
+    int main(void) {
+        // This is target object.
+        std::vector<std::string> target;
+        target.push_back("Hello,");
+        target.push_back("World!");
+
+        // Serialize it.
+        msgpack::sbuffer buffer;  // simple buffer
+        msgpack::pack(&buffer, target);
+    
+        // Deserialize the serialized data.
+        msgpack::zone mempool;    // this manages the life of deserialized object
+        msgpack::object obj;
+        msgpack::unpack_return ret =
+                msgpack::unpack(buffer.data, buffer.size, NULL, &mempool, &obj);
+
+        if(ret != msgapck::UNPACK_SUCCESS) {
+            // error check
+            exit(1);
+        }
+    
+        // Print the deserialized object to stdout.
+        std::cout << obj << std::endl;    // ["Hello," "World!"]
+    
+        // Convert the deserialized object to staticaly typed object.
+        std::vector<std::string> result;
+        obj.convert(&result);
+    
+        // If the type is mismatched, it throws msgpack::type_error.
+        obj.as<int>();  // type is mismatched, msgpack::type_error is thrown
+    }
