RapidJSON is a fast JSON parser and generator for C++.  It was
inspired by RapidXml.

RapidJSON is small but complete.  It supports both SAX and DOM style
API. The SAX parser is only a half thousand lines of code.

RapidJSON is fast.  Its performance can be comparable to strlen().
It also optionally supports SSE2/SSE4.1 for acceleration.

RapidJSON is self-contained.  It does not depend on external
libraries such as BOOST.  It even does not depend on STL.

RapidJSON is memory friendly.  Each JSON value occupies exactly
16/20 bytes for most 32/64-bit machines (excluding text string). By
default it uses a fast memory allocator, and the parser allocates
memory compactly during parsing.

RapidJSON is Unicode friendly.  It supports UTF-8, UTF-16, UTF-32
(LE & BE), and their detection, validation and transcoding
internally. For example, you can read a UTF-8 file and let RapidJSON
transcode the JSON strings into UTF-16 in the DOM. It also supports
surrogates and "\u0000" (null character).

JSON(JavaScript Object Notation) is a light-weight data exchange
format. RapidJSON should be in fully compliance with RFC4627/ECMA-404.
