This example shows how to use Gelex with iss-yacc from Halstenbach.
The directory contains the source code of the calculator example provided
with iss-yacc and the associated lexical analyzer generated with Gelex.

To compile this example:

1. Use the script 'make parser' to generate class CALC_PARSER and
   'make scanner' to generate class CALC_SCANNER if necessary.
2. Use your HACT Eiffel compiler to compile the Eiffel system using
   the provided Ace file (hact.ace). If you have GNU make, you can
   alternatively type: 'make hact'.
3. Run the calcultor:
       calculator
   and enter infix notation expressions to be evaluated, one per line.
