MaGIC (Matrix Generator for Implication Connectives) is a tool that produces small algebraic models of non-classical propositional logics, especially of the substructural sort. The logics are considered as Hilbert (axiom) systems. Interaction with MaGIC is through a plain text "terminal" window and is based on a menu. Help is available from the menu. Synopsis: magic [-b ] [-t] [-x] Options: -b runs the program in batch mode with the specified file as input. The file should be one previously saved with the "Save" option from a previous run of MaGIC. This allows output to be piped through another program such as one of the utilities provided with MaGIC. -t produces "terse" output, mainly meaning that it suppresses system calls such as those that clear the window each time the menu is printed. -x causes the dialogue to be in a form suitable for "xmagic", the (now defunct) X Windows interface to MaGIC. It is the result of a message from Gustav Meglicki to John Slaney to the effect that the machine-readable I/O was "insufficiently user-hostile". Since xmagic is no longer supported, this option is a mere relic. Installation: The main directory containing this README should have two subdirectories, one containing the program sources and the other containing various data files used by MaGIC. To make, go to the src directory and edit the Makefile. Only the top few lines require any change - mainly it is a matter of filling in the directories where the data files and the binaries are to be kept. Then "make" should make the programs and "make install" should simply move them and the data into the specified directories.As usual, "make clean" removes the .o files and possibly other junk. Problems in installing or using MaGIC should be reported to the author John.Slaney@anu.edu.au It is also recommended that if you install MaGIC you let us know, so that we can inform you of any bug fixes or updates.
