  - Initialize SDL and CRM32Pro.
  - Printing help on a window.
  - Use of log system.
  - Initialize graphics: window icon, video mode and cursor.
  - Initialize sound system.
  - Use of time system.
  - Blit a surface
  - Using the integrated console and debug window
  - Exiting using the right way ;)
