 \section{Introduction}\label{intro}
 Computer Theorem Provers (CTPs \footnote{The term CTP is used to address two different things in this paper: (1) the academic discipline comprising respective theories as well as (2) the products developed within this discipline, the provers and the respective technology.}) have a tradition as long as Computer Algebra Systems (CAS), another kind of mathematics assistants. However, CTPs task of proving is more challenging than calculating; so, in contrary to CASs, CTPs are not yet in widespread use --- not yet, because CTPs are on the step into industrial use in the current decade: Safe-critical software requires to be proven correct more and more \cite{db:dom-eng}, and the technology of CTP becomes ready to accomplish the task of efficiently proving hundreds of proof obligations.
