+// Selector base class for analysis based on whole AliRoot
+// Please derive your selector-based analysis from this class, if you need to access the
+// RunLoader or anything provided by it.
 //
 // This selector depends on the RunLoader, therefore to use it you have to have the whole AliRoot available
 // The benefit is that you can use the RunLoader to access everything in the data structure
-// If you only have the ESD library use AliSelector instead
 //
+// The class has functions to return the stack (GetStack()), the RunLoader (GetRunLoader()), and
+// the event header (GetHeader()).
