	SoundManager 2 buildfile (Ant)

	This is tested on OS X and Windows and uses Google's Closure Compiler (JS), MTASC (Flash 8) and mxmlc (Adobe Flex Open Source SDK) for the Flash 9 build.
	Perl is used only to display file sizes during compilation, and can be commented out if you don't have it installed.

    USAGE

	- Go to the soundmanager2 root directory (ie., where this build.xml file is.)
	- Create the file .build.properties containing the paths to the external tools.
	  For example, on Windows:

		closure-compiler.jar=C:\\Tools\\closure\\compiler.jar
		mtasc=C:\\Tools\\mtasc\\mtasc.exe
		mxmlc=C:\\Tools\\flex_sdk\\bin\\mxmlc.exe

	- Run "ant"

    Adobe Flex Open Source SDK (including mxmlc compiler) for AS3/Flash 9 SWF
	http://opensource.adobe.com/wiki/display/flexsdk/Flex+SDK
	** NOTE: ExternalInterface issues were found in SWFs compiled with Flex SDK version 4.5.1.21328. Do not use 4.5.x. Instead, use Flex SDK version 4.1.0.16076 to be safe, which has been confirmed to work with SM2 (Flash 9 version.) **

	WHAT IS AUTOMATED

	* Build of soundmanager-jsmin.js from soundmanager2.js (google closure compiler compression)
	* Build of soundmanager-nodebug.js and soundmanager-nodebug-jsmin.js (above, plus stripping out <d>-annotated sections</d> of debug functionality, eg. writeDebug() and debug strings etc.)
	* Build of AS2/AS3 SWFs from .AS source, plus debug-enabled versions. Additionally, cross-domain-enabled versions are made and placed into a zip file.

	MAKING THIS SUCK LESS (TODO)

	* Split up actions (ie., option to do only JS, only SWFs etc. vs. full build)
