It's that tiny little programm like Fritz6 or Fritz6 a b or c. Or any basic
instructions of any chess programm, evaluation, mobility etc.
It's like  an engine you put into a car or a CPU you put into a computer if I
may dare make such an analogy?;) Alone it's not enough but it is the _heart_ of
the chess programm.
Knowing which is the strongest engine seems logical to me and then build around
it.
