	Title:
		SDL_gfx Example

	Description:
		This is an example of how to use the SDL_gfx DevKit.  After the dev kit
		is installed into Dev-C++, you should be able to goto New Project and
		see the SDL_gfx Example project available there.  SDL_gfx is a great
		graphics library for SDL.  More information is available about it at
		http://www.ferzkopp.net/~aschiffler/Software/SDL_gfx-2.0/

	Author:
		Rob Loach (http://www.robloach.net)

	Date:
		February 8th, 2005

	Note:
		REQUIRED - You must copy SDL.dll, SDL_gfx.dll and sample24.bmp
		from Dev-C++/DLL directory to the folder where you saved this
		project.

		When making a new project, you must link to -lSDL_gfx.
