{\GAP} can be copied and distributed freely for any non-commercial
purpose.

If you copy {\GAP} for somebody else, you may ask this person for refund
of your expenses. This should cover cost of media, copying and shipping.
You are not allowed to ask for more than this. In any case you must give
a copy of this copyright notice along with the program.

If you obtain {\GAP} please send us a short notice to that effect, e.g.,
an e-mail message to the address `gap@samson.math.rwth-aachen.de',
containing your full name and address. This allows us to keep track of
the number of {\GAP} users.

If you publish a mathematical result that was partly obtained using
{\GAP}, please cite {\GAP}, just as you would cite another paper that you
used. Also we would appreciate it if you could inform us about such a
paper.

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.

{\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}.
