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! * * 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.
