# MXMLC Quickbuild Script v.2010-06-13
# 
# Based on the Quickbuild feature found in FlashDevelop: 
#   http://www.flashdevelop.org/wikidocs/index.php?title=QuickBuild
#
# Author: 
#   David Knape, http://www.bumpslide.com/
#
# Usage: 
#   quickbuild [-n] filename
# 
# Options:
#   -n  No Launch, just build.
#
# This ruby script is meant to be run from the command line or 
# from an IDE that has been configured to launch an external tool.
#
# The input file is used as the target for a call to mxmlc.  
# Compiler options are parsed from the @mxmlc comment doc attribute.
#
# Example @mxmlc tag in AS3 Class:
#
#   package { 
#     import flash.display.*; 
#     import flash.text.*;
#     /**
#      * Compile with $ quickbuild TestApp.as
#      * @mxmlc -target-player=10 -static-link-runtime-shared-libraries -debug -default-size 500 200 -o test.swf
#      */
#     public class TestApp extends Sprite {
#       public function TestApp() { 
#         with(graphics){beginFill(0xDF6559);drawRect(10,10,480,180);endFill();}
#         with(addChild(new TextField()) as TextField){ x=y=20; width=500;
#           defaultTextFormat=new TextFormat('Arial', 30, 0xFFFFFF,true);
#           text="Hello, Bumpslide Quickbuild."; };
#   } } }
