tpl: Simple, Lightweight Serialization for C

"There are no library dependencies. You can compile its source code (one file) right into your program."

Should come in handy when you want to do some quick serialization/deserialization but doesn't have the time or is overkill to bring in a heavy duty player (or if you are working in pure C). The API looks simple and elegant. License is BSD.
