The count scripting command yields inconsistent results on config classes. Usually it counts all entries in a class, including inherited. For example:

class A {

entry1 = 1;
entry2 = 2;

};

class B : A {

entry3 = 3;

};

A count on A yields 2, and a count on B yields 3, as expected.

However:
class C: B {
};

yields zero, since the class only inherit but doesn't define any entries itself.
