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! - * - * LICENSE: Redistribution and use in source and binary forms, with or - * without modification, are permitted provided that the following - * conditions are met: Redistributions of source code must retain the - * above copyright notice, this list of conditions and the following - * disclaimer.
