        Runtime Environment, as provided by the publisher or creator of said Runtime

        AND QUALITY OF THE PROGRAM LIES WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, 
        YOU WILL ASSUME ALL COSTS FOR REQUIRED REPAIR OR CORRECTION.

Differences with version 1.0

There is one major difference between this version and /Version 1.0 and that is that this version does not contain the clause

        The right to "port" the Program to another runtime environment is reserved for 
        the copyright holder.

This clause was meaningless. Creating a port of the program is equal to creating a derivate. Creating a derivate of the program was already allowed. Therefor this clause has been removed from the license.
