+ * Converts to and from JSON format.
+ *
+ * JSON (JavaScript Object Notation) is a lightweight data-interchange
+ * format. It is easy for humans to read and write. It is easy for machines
+ * to parse and generate. It is based on a subset of the JavaScript
+ * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
+ * This feature can also be found in Python. JSON is a text format that is
+ * completely language independent but uses conventions that are familiar
+ * to programmers of the C-family of languages, including C, C++, C#, Java,
+ * JavaScript, Perl, TCL, and many others. These properties make JSON an
+ * ideal data-interchange language.
+ *
+ * This package provides a simple encoder and decoder for JSON notation. It
+ * is intended for use with client-side Javascript applications that make
+ * use of HTTPRequest to perform server communication functions - data can
+ * be encoded into JSON notation for use in a client-side javascript, or
+ * decoded from incoming Javascript requests. JSON format is native to
+ * Javascript, and can be directly eval()'ed with no further parsing
+ * overhead
+ *
+ * All strings should be in ASCII or UTF-8 format!
