-#  Try Spiffy Decode
-
-A major new version of QCBOR has Spiffy Decode which makes it much easier to 
-implement CBOR decoding.
-
-The decoding implementation of a protocol looks like the encoding implementation:
-
-     /* Encode */
-     QCBOREncode_Init(&EncodeCtx, Buffer);
-     QCBOREncode_OpenMap(&EncodeCtx);
-     QCBOREncode_AddTextToMap(&EncodeCtx, "Manufacturer", pE->Manufacturer);
-     QCBOREncode_AddInt64ToMap(&EncodeCtx, "Displacement", pE->uDisplacement);
-     QCBOREncode_AddInt64ToMap(&EncodeCtx, "Horsepower", pE->uHorsePower);
-     QCBOREncode_CloseMap(&EncodeCtx);
-     uErr = QCBOREncode_Finish(&EncodeCtx, &EncodedEngine);
-  
-     /* Decode */
-     QCBORDecode_Init(&DecodeCtx, EncodedEngine, QCBOR_DECODE_MODE_NORMAL);
-     QCBORDecode_EnterMap(&DecodeCtx);
-     QCBORDecode_GetTextStringInMapSZ(&DecodeCtx, "Manufacturer", &(pE->Manufacturer));
-     QCBORDecode_GetInt64InMapSZ(&DecodeCtx, "Displacement", &(pE->uDisplacement));
-     QCBORDecode_GetInt64InMapSZ(&DecodeCtx, "Horsepower", &(pE->uHorsePower));
-     QCBORDecode_ExitMap(&DecodeCtx);
-     uErr = QCBORDecode_Finish(&DecodeCtx);
-
-With the previous decoding API (which is still supported), the decode implementation 
-is 5-10 times longer.
-
-While the QCBOR library is larger, it reduces the object code needed to call it by a lot,
-so if you have to decode multiple maps, overall object code is likely to go down.
-
-While this new version is backwards compatible, it is a large change so it is not
-yet merged into the QCBOR master. It needs more testing before that happens.
-
-This new version is in SpiffyDecode branch so you have to explicitly go and get that branch.
-
-This version also improves tag handling a lot, adds duplicate map label detection and fixes
-some bugs with CBOR that is a combination of definite and indefinite lengths.
