+//------------------------------------
+
+// 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 preceded 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)
+//   - Length 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]...
+//   - time.Time are encoded as [bd] [length] [byte]...
+//
+// The full spec will be published soon.
