The brainfuck interpreter knows the following instructions:

Cmd  Effect                               
---  ------                               
+    Increases element under pointer      
-    Decrases element under pointer       
>    Increases pointer                    
<    Decreases pointer                    
[    Starts loop, flag under pointer      
]    Indicates end of loop                
.    Outputs ASCII code under pointer

Who can program anything useful with it? :)
