GAP is distributed by us without any warranty, to the extent permitted by applicable state law. We distribute GAP as is without warranty of any kind, either expressed or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose.

The entire risk as to the quality and performance of the program is with you. Should GAP prove defective, you assume the cost of all necessary servicing, repair or correction.

In no case unless required by applicable law will we, and/or any other party who may modify and redistribute GAP as permitted above, be liable to you for damages, including lost profits, lost monies or other special, incidental or consequential damages arising out of the use or inability to use GAP.

You are permitted to modify and redistribute GAP, but you are not allowed to restrict further redistribution. That is to say proprietary modifications will not be allowed. We want all versions of GAP to remain free.

If you modify any part of GAP and redistribute it, you must supply a `README` document. This should specify what modifications you made in which files. We do not want to take credit or be blamed for your modifications.

Of course we are interested in all of your modifications. In particular we would like to see bug-fixes, improvements and new functions. So again we would appreciate it if you would inform us about all modifications you make.
