#-------- Make AS Def Script -----------------------------------------------------------------------------
#Author: 		Michael Bianco, <info@mabwebdesign.com>, http://developer.mabwebdesign.com/
#Description:	Parses through AS files ending in .as, or .actionscript and pulls out variable, class, and function defitions
#				and prepares them for use in xcode. This script is *not* bullet proof, and will include all variables declared with the 'var' keyword in the 
#				output file. Because of this the different type of definitions are seperated into differenet temporary files so you can easily include only 
#				which definitions you want (I.E. Functions, Variables, Class definitions) by changing the cat command near the end of the script.
#				This script only supports AS2 class construction syntax Functions that have no arguments (Ex. doSomething()), are stripped of their parenthesis.
