2021 Update - The code in this Gist has been compiled into a haxelib for a more convenient experience! Please upgrade as this Gist will no longer be updated! Check out the repo here: https://github.com/AustinEast/echo-flixel

After that, you're ready to go! Check out 03-PlayState.hx to see a simple example of how to use FlxEcho.

	This file will get included twice - once at the beginning - once at the end.

	The first time though, the "vars" section is parsed, and this is where you can
	set variables to control the setup of the standard compilers and install paths etc.

	The second time, the "exes" section is parsed, and you can modify the linkers/compilers
	by adding flags to these executables.
