+PicoJSON is a tiny JSON parser / serializer for C++ with the following
+properties:
+
+* Header-file only
+* No external dependencies (only uses standard C++ libraries)
+* STL-friendly (arrays are represented using std::vector, objects are std::map)
+* Provides both pull interface and streaming (event-based) interface
