Yes.

The way to change it for now will be to add this line to your init()  
method:

   SearchMan.addDirectory(dir.getPath(), dir, 0, 5);

In my head, the plan always was the following: Get rid of this call to  
SearchMan.addDirectory() in base/main.cpp (maybe even all of them).  
Instead, let's add a virtual method "initPaths" or "setupPaths" to  
class Engine, which by default contains these calls to  
SearchMan.addDirectory, and which subclasses overload as desired  
(essentially moving all Engine specific calls to  
SearchMan.addDirectory() there). Then invoke that method from  
runGame() in base/main.cpp instead of the addDirectory calls there.
