Our new map is now ready to the first test! Go to the freeVikings directory and invoke freevikings.rb as follows:

	  [igneus@vidhost freeVikings]$ ./freevikings.rb -l YOUR/LEVEL/DIRECTORY
	

For example I want to play the example level for this chapter:

	  [igneus@vidhost freeVikings]$ ./freevikings.rb -l ./docs/develop_guide/examples/CH1_FirstMap/
	

Option -l tells freeVikings to load level (or, as you will see later, a set of levels) from directory given as argument to the option. So when you start new game as usual, instead of the familiar first ice level with bear you see your new level!
