00052 --- Kyra Splash Screen.
00053 
00054         It would be appreciate if you display the Kyra splash screen when using
00055         either license, however it is only required for the LGPL. All the
00056         resources for the splash are compiled into the library, and it can be
00057         accessed through the following API:
00058 
00059                 KrEngine::StartSplash
00060                 KrEngine::UpdateSplash
00061                 KrEngine::EndSplash
00062 
00063         Full documentation is provided with the KrEngine class. The splash screen
00064         should be displayed for 2 seconds.
00065 
00066         Thank you.
