re-implemented in Isabelle/HOL the quotient package by Homeier. In doing so we
extended his work in order to deal with compositions of quotients. Also, we
designed our quotient package so that every step in a quotient construction
-can be performed separately and as a result we were able to specify completely

The importance for programming language research is that many properties of
programming language calculi are easier to verify over $\alpha$-equated, or
