Description : translating a HasCASL subset to Isabelle

Copyright : (c) C. Maeder, DFKI 2006

License : GPLv2 or higher, see LICENSE.txt

Maintainer : Christian.Maeder@dfki.de

Stability : provisional

Portability : non-portable (imports Logic.Logic)

The embedding comorphism from HasCASL without subtypes to

Isabelle-HOL. Partial functions yield an option or bool result in

Isabelle. Case-terms and constructor classes are not supported yet.
