I have a work in progress patch to tty out message pack format to emit

it is header only library available under boost license. But however if
this is sufficient for my experiment I would love to use this.

Hi Vivek,

I'm glad to hear there is some interest in the library. From a quick
look at msgpack-c it appears this should be sufficient, but if you
get a chance to look at my API please let me know if there is anything
you need which is missing.

As I mentioned, there is no equivalent to msgpack-c's MSGPACK_DEFINE
for user-defined structs, but I plan to implement something similar.

Regards,
Scott
