 **Small simple memory model** – Malloc is not needed. The encode context is 136 bytes, decode context is 104 bytes and the description of decoded data item is 56 bytes. Stack use is light and there is no recursion. The caller supplies the memory to hold the encoded CBOR and encode/decode contexts so caller has full control of memory usage making it good for embedded implementations that have to run in small fixed memory. 
 
-**Supports nearly all of RFC 7049** – Only minor, corner-case parts of RFC 7049 are not directly supported (canonicalization, decimal fractions, big floats). Decoding
-indefinite length strings but requires a string allocator (see documentation). Encoding indefinite length strings is not supported, but

 ## Building
 There is a simple makefile for the UNIX style command line binary that compiles everything to run the tests.

 For most use cases you should just be able to add them to your project. Hopefully the easy portability of this implementation makes this work straight away, whatever your development environment is.

 impact code size. The decoding side is about 150 bytes of object code. It is never dead stripped because it directly referenced by
 the core decoder, however it doesn't add very much to the size.
 
 The test directory includes some tests that are nearly as portable as the main implementation.  If your development environment 
 doesn't support UNIX style command line and make, you should be able to make a simple project and add the test files to it.
