CIFF Installation ================= CIFF is a collection of Prolog files that are being distributed in a compressed archive. To decompress and extract the individual files, you can use the following command (under Linux/Unix): >> tar xvzf ciff-3.0.tar.gz Under Windows you can use WinZip or similar programs. You require Sicstus Prolog to run CIFF (tested under version 3.11.2). To run the (optional) graphical user interface, you also require Tcl/Tk. Further instructions are available in the README file and in ciff-main.pl.
