+High Performance, Feature-Rich Idiomatic Go encoding library for msgpack and binc .
+
+Supported Serialization formats are:
+
+  - msgpack: [https://github.com/msgpack/msgpack]
+  - binc: [http://github.com/ugorji/binc]
+
+To install:
+
+    go get github.com/ugorji/go/codec
+
+The idiomatic Go support is as seen in other encoding packages in
+the standard library (ie json, xml, gob, etc).
+
+Rich Feature Set includes:
+
+  - Simple but extremely powerful and feature-rich API
+  - Very High Performance.
+    Our extensive benchmarks show us outperforming Gob, Json and Bson by 2-4X.
+    This was achieved by taking extreme care on:
+      - managing allocation
+      - function frame size (important due to Go's use of split stacks),
+      - reflection use (and by-passing reflection for common types)
+      - recursion implications
+      - zero-copy mode (encoding/decoding to byte slice without using temp buffers)
+  - Correct.
+    Care was taken to precisely handle corner cases like:
+      overflows, nil maps and slices, nil value in stream, etc.
+  - Efficient zero-copying into temporary byte buffers
+    when encoding into or decoding from a byte slice.
+  - Standard field renaming via tags
+  - Encoding from any value
+    (struct, slice, map, primitives, pointers, interface{}, etc)
+  - Decoding into pointer to any non-nil typed value
+    (struct, slice, map, int, float32, bool, string, reflect.Value, etc)
+  - Supports extension functions to handle the encode/decode of custom types
+  - Support Go 1.2 encoding.BinaryMarshaler/BinaryUnmarshaler
+  - Schema-less decoding
+    (decode into a pointer to a nil interface{} as opposed to a typed non-nil value).
+    Includes Options to configure what specific map or slice type to use
+    when decoding an encoded list or map into a nil interface{}
+  - Provides a RPC Server and Client Codec for net/rpc communication protocol.
+  - Msgpack Specific:
+      - Provides extension functions to handle spec-defined extensions (binary, timestamp)
+      - Options to resolve ambiguities in handling raw bytes (as string or []byte)
+        during schema-less decoding (decoding into a nil interface{})
+      - RPC Server/Client Codec for msgpack-rpc protocol defined at:
+        https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md
+  - Fast Paths for some container types:
+    For some container types, we circumvent reflection and its associated overhead
+    and allocation costs, and encode/decode directly. These types are:
+	    []interface{}
+	    []int
+	    []string
+	    map[interface{}]interface{}
+	    map[int]interface{}
+	    map[string]interface{}
+
+Extension Support
+
+Users can register a function to handle the encoding or decoding of
+their custom types.
+
+There are no restrictions on what the custom type can be. Some examples:
+
+    type BisSet   []int
+    type BitSet64 uint64
+    type UUID     string
+    type MyStructWithUnexportedFields struct { a int; b bool; c []int; }
+    type GifImage struct { ... }
+
+As an illustration, MyStructWithUnexportedFields would normally be
+encoded as an empty map because it has no exported fields, while UUID
+would be encoded as a string. However, with extension support, you can
+encode any of these however you like.
+
+RPC
+
+RPC Client and Server Codecs are implemented, so the codecs can be used
+with the standard net/rpc package.
+
+Usage
+
+Typical usage model:
+
+    // create and configure Handle
+    var (
+      bh codec.BincHandle
+      mh codec.MsgpackHandle
+    )
+
+    mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
+
+    // configure extensions
+    // e.g. for msgpack, define functions and enable Time support for tag 1
+    // mh.AddExt(reflect.TypeOf(time.Time{}), 1, myMsgpackTimeEncodeExtFn, myMsgpackTimeDecodeExtFn)
+
+    // create and use decoder/encoder
+    var (
+      r io.Reader
+      w io.Writer
+      b []byte
+      h = &bh // or mh to use msgpack
+    )
+
+    dec = codec.NewDecoder(r, h)
+    dec = codec.NewDecoderBytes(b, h)
+    err = dec.Decode(&v)
+
+    enc = codec.NewEncoder(w, h)
+    enc = codec.NewEncoderBytes(&b, h)
+    err = enc.Encode(v)
+
+    //RPC Server
+    go func() {
+        for {
+            conn, err := listener.Accept()
+            rpcCodec := codec.GoRpc.ServerCodec(conn, h)
+            //OR rpcCodec := codec.MsgpackSpecRpc.ServerCodec(conn, h)
+            rpc.ServeCodec(rpcCodec)
+        }
+    }()
+
+    //RPC Communication (client side)

+    rpcCodec := codec.GoRpc.ClientCodec(conn, h)

+// SimpleHandle is a Handle for a very simple encoding format.
+//
+// simple is a simplistic codec similar to binc, but not as compact.
+//   - Encoding of a value is always preceeded by the descriptor byte (bd)
+//   - True, false, nil are encoded fully in 1 byte (the descriptor)
+//   - Integers (intXXX, uintXXX) are encoded in 1, 2, 4 or 8 bytes (plus a descriptor byte).
+//     There are positive (uintXXX and intXXX >= 0) and negative (intXXX < 0) integers.
+//   - Floats are encoded in 4 or 8 bytes (plus a descriptor byte)
+//   - Lenght of containers (strings, bytes, array, map, extensions)
+//     are encoded in 0, 1, 2, 4 or 8 bytes.
+//     Zero-length containers have no length encoded.
+//     For others, the number of bytes is given by pow(2, bd%3)
+//   - maps are encoded as [bd] [length] [[key][value]]...
+//   - arrays are encoded as [bd] [length] [value]...
+//   - extensions are encoded as [bd] [length] [tag] [byte]...
+//   - strings/bytearrays are encoded as [bd] [length] [byte]...
+//

+// EncodeTime encodes a time.Time as a []byte, including
+// information on the instant in time and UTC offset.
+//
+// Format Description
+//
+//   A timestamp is composed of 3 components:
+//
+//   - secs: signed integer representing seconds since unix epoch
+//   - nsces: unsigned integer representing fractional seconds as a
+//     nanosecond offset within secs, in the range 0 <= nsecs < 1e9
+//   - tz: signed integer representing timezone offset in minutes east of UTC,
+//     and a dst (daylight savings time) flag
+//
+//   When encoding a timestamp, the first byte is the descriptor, which
+//   defines which components are encoded and how many bytes are used to
+//   encode secs and nsecs components. *If secs/nsecs is 0 or tz is UTC, it
+//   is not encoded in the byte array explicitly*.
+//
+//       Descriptor 8 bits are of the form `A B C DDD EE`:
+//           A:   Is secs component encoded? 1 = true
+//           B:   Is nsecs component encoded? 1 = true
+//           C:   Is tz component encoded? 1 = true
+//           DDD: Number of extra bytes for secs (range 0-7).
+//                If A = 1, secs encoded in DDD+1 bytes.
+//                    If A = 0, secs is not encoded, and is assumed to be 0.
+//                    If A = 1, then we need at least 1 byte to encode secs.
+//                    DDD says the number of extra bytes beyond that 1.
+//                    E.g. if DDD=0, then secs is represented in 1 byte.
+//                         if DDD=2, then secs is represented in 3 bytes.
+//           EE:  Number of extra bytes for nsecs (range 0-3).
+//                If B = 1, nsecs encoded in EE+1 bytes (similar to secs/DDD above)
+//
+//   Following the descriptor bytes, subsequent bytes are:
+//
+//       secs component encoded in `DDD + 1` bytes (if A == 1)
+//       nsecs component encoded in `EE + 1` bytes (if B == 1)
+//       tz component encoded in 2 bytes (if C == 1)
+//
+//   secs and nsecs components are integers encoded in a BigEndian
+//   2-complement encoding format.
+//
+//   tz component is encoded as 2 bytes (16 bits). Most significant bit 15 to
+//   Least significant bit 0 are described below:
+//
+//       Timezone offset has a range of -12:00 to +14:00 (ie -720 to +840 minutes).
+//       Bit 15 = have\_dst: set to 1 if we set the dst flag.
+//       Bit 14 = dst\_on: set to 1 if dst is in effect at the time, or 0 if not.
+//       Bits 13..0 = timezone offset in minutes. It is a signed integer in Big Endian format.
