// //
// This base class is actually a quite-recent addition. As a result, most //
// of the old, non-base-class-structured code is still lying around. This //
// code will be slowly converted over as time goes on; the theory was that //
// this conversion would be far more likely to occur if the base class //
// actually already existed. //
