 Note: to integrate your apps into the build 
     make clean-configs
     put your application into a sourcedir
     edit $OPIEDIR/packages

+Naming Conventions:
+    Most of the time we prefix member variables with m_. This allows
+    us to see if a variable in a function is a member
+    or on the stack.
+    Function naming we use setFooBar() but fooBar() to get the
+    value. So please skip the get you're used from Java.
+    Other than that please try to avoid #ifdef and #defines
+    use const but we do not have any coding style convetions.
