// Project: LoadFPSCLevel
// Created: 12/31/2011

// Stripped down source code and steps for bare bones FPSC level loading.

// 1. Run FPSCREATOR.EXE. 
// 2. Scroll to the TOP/LEFT corner of the default level (level 5) in the editing area.
// 3. Make a level starting from this corner.
// 3. Click the TEST LEVEL button to build the test level.
// 4. Exit FPSCREATOR.EXE.
// 5. Move this compiled executable to the FPSCREATOR directory.
// 6. From the FPSCREATOR directory run LoadFPSCLevel.exe.

// Whenever using Dark GDK you must ensure you include the header file.
