+   * 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!
