This document is part of the CoFI Catalogue of Algebraic Specification Frameworks. It was provided by Hubert Baumeister; any comments and corrections should be addressed to Hubert.Baumeister@mpi-sb.mpg.de.

It will be made available formatted for printing as compressed Postscript (~100Kb) and DVI (~50Kb).

The WWW version provides only a rough approximation (mostly generated automatically by Hyperlatex) to the symbols used in the formatted versions. Please inform pdmosses@brics.dk about any places where an alternative approximation is desirable!

N.B. All sections of the catalogue are TENTATIVE first versions, unless explicitly marked otherwise. Sections dealing with Methodology, Tools, and Documentation will be added later.
