 # Circular dependencies
 
+Avoiding a pattern that can cause problems at compile-time
 
 
 In software, a circular dependency is a relation between two or more classes which either directly or indirectly depend on each other to function properly. An extreme example, which could not work, is:

 Fortunately, the Royale compiler has an option called -remove-circulars that is on by default. It analyzes the code and determines which goog.require to remove so GCC won't complain about the circularities and can load the scripts in the right order. However, if you want to know how to refactor your code so that you don't create what GCC considers to be circular dependencies, read on.
 
+### Refactoring interdependent classes
+
 GCC recommends refactoring interdependent classes to use interfaces. Some folks believe that classes should never reference other classes, only interfaces. There are some advantages to this approach, but it is more work.
 
 You would define two interfaces like this:
