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.
