This README belongs to a "The heterogeneous tool set" (Hets) release

(and does not apply to sources directly obtained via cvs).

Information not contained here can be found in the Hets user guide

(doc/UserGuide.pdf) or on the Hets web page (www.tzi.de/cofi/hets).

The subject of this release is a binary "hets" that is able to analyse

heterogeneous and in particular CASL specifications.

The sources need to be compiled with ghc Glasgow Haskell Compiler

(www.haskell.org/ghc). Haskell is also a part of Hets via

"Programatica" (www.cse.ogi.edu/PacSoft/projects/programatica).

Beside output written to the console (stdout) or to files hets can

display graphs using "uDraw(Graph)", formerly "daVinci"

(www.informatik.uni-bremen.de/uDrawGraph)

For hets to find "uDrawGraph", the environment variables UDG_HOME and

UNIDAVINCI must be set to the installation directory of uDraw(Graph) and to

the actual executable, respectively.

export UNIDAVINCI=$UDG_HOME/bin/uDrawGraph

A typical call of hets is then: hets -g Basic/Numbers.casl

If you need to rebuild the hets binary follow the instructions in INSTALL

(This README belongs a to release created by "make release", in case

that you obtained the HetCATS sources as CVS tree)

The heterogeneous tool set (Hets) is mainly maintained by

Christian Maeder (maeder@tzi.de, initials CM) and Till Mossakowski

(till@tzi.de, initials TM). The mailing list is hets-devel@tzi.de.
