     If you obtain GAP please send us a short notice to that effect, e.g., 
an  e-mail  message  to the address <gap@dcs.st-and.ac.uk>, 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
(see  below  for  sample  citation).  Also we would appreciate if you could
inform us about such a paper.

     Specifically, please refer to

     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.
