Description : CspCASL instance of type class logic

Copyright : (c) Markus Roggenbach, Till Mossakowski and Uni Bremen 2003

License : GPLv2 or higher, see LICENSE.txt

Maintainer : M.Roggenbach@swansea.ac.uk

Stability : experimental

Portability : non-portable(import Logic.Logic)

Here is the place where the class Logic is instantiated for CspCASL. A

CspCASL signature is a CASL signature with a set of named channels and

processes. Every process has a profile. Morphisms are supposed to allow

renaming of channels and processes, too. Also sublogics (as a superset of some

CASL sublogics) are still missing.
