+// This header defines the interface convention used in the valve engine.
+// To make an interface and expose it:
+//    1. Derive from IBaseInterface.
+//    2. The interface must be ALL pure virtuals, and have no data members.
+//    3. Define a name for it.
+//    4. In its implementation file, use EXPOSE_INTERFACE or EXPOSE_SINGLE_INTERFACE.
+
+// Versioning
+// There are two versioning cases that are handled by this:
+// 1. You add functions to the end of an interface, so it is binary compatible with the previous interface. In this case, 
+//    you need two EXPOSE_INTERFACEs: one to expose your class as the old interface and one to expose it as the new interface.
+// 2. You update an interface so it's not compatible anymore (but you still want to be able to expose the old interface 
+//    for legacy code). In this case, you need to make a new version name for your new interface, and make a wrapper interface and 
+//    expose it for the old interface.
