3. Digital Creations requests that attribution be given to Zope
   in any manner possible. Zope includes a "Powered by Zope"
   button that is installed by default. While it is not a license
   violation to remove this button, it is requested that the
   attribution remain. A significant investment has been put
   into Zope, and this effort will continue if the Zope community
   continues to grow. This is one way to assure that growth.

4. All advertising materials and documentation mentioning
   features derived from or use of this software must display
   the following acknowledgement:

     "This product includes software developed by Digital Creations
     for use in the Z Object Publishing Environment
     (http://www.zope.org/)."

   In the event that the product being advertised includes an
   intact Zope distribution (with copyright and license included)
   then this clause is waived.

5. Names associated with Zope or Digital Creations must not be used to
   endorse or promote products derived from this software without
   prior written permission from Digital Creations.
 
6. Modified redistributions of any form whatsoever must retain
   the following acknowledgment:

      "This product includes software developed by Digital Creations
      for use in the Z Object Publishing Environment
      (http://www.zope.org/)."
 
    Intact (re-)distributions of any official Zope release do not
    require an external acknowledgement.
 
 7. Modifications are encouraged but must be packaged separately as
    patches to official Zope releases.  Distributions that do not
    clearly separate the patches from the original work must be clearly
    labeled as unofficial distributions.  Modifications which do not
    carry the name Zope may be packaged in any form, as long as they
    conform to all of the clauses above.
