+<p>If a class is defined in a header file and has a v-table (either it has 
+virtual methods or it derives from classes with virtual methods), it must 
+always have at least one out-of-line virtual method in the class.  Without 
+this, the compiler will copy the vtable and RTTI into every .o file that
+#includes the header, bloating .o file sizes and increasing link times.
