The Great Information Factory has always provided the program source code to our customers. This is done under a license agreement that allows you to maintain the programs yourself if you choose. The license agreement precludes you from reselling or transferring the source to any other end-user. Yet, it allows you to maintain and modify the programs according to your needs. TGIF does not assume responsibility for the programs once modified by the end-user. However, our staff is always available to assist you when you choose to maintain the software yourself.
