+has been tested under Linux, FreeBSD, OSX, Solaris and Windows.
+
+Features:
+
+- Fast, standards compliant encoding/parsing routines.
+- Full support for JSON with UTF-8, including decoding surrogate pairs.
+- Optional run-time support for common exceptions to the JSON specification
+  (NaN, Infinity,..).
+- No external dependencies.
