To configure the parser generater under Unix or cygwin, simply type
% make *scheme-system*where *scheme-system* is one of

The exact list of supported Scheme systems may differ from this list.
Typing make without any argument will list all supported systems.
The configuration will generate a file lalr.scm containing the
