  22 # 3. Digital Creations requests that attribution be given to Zope
  23 #    in any manner possible. Zope includes a "Powered by Zope"
  24 #    button that is installed by default. While it is not a license
  25 #    violation to remove this button, it is requested that the
  26 #    attribution remain. A significant investment has been put
  27 #    into Zope, and this effort will continue if the Zope community
  28 #    continues to grow. This is one way to assure that growth.
  29 #
  30 # 4. All advertising materials and documentation mentioning
  31 #    features derived from or use of this software must display
  32 #    the following acknowledgement:
  33 #
  34 #      "This product includes software developed by Digital Creations
  35 #      for use in the Z Object Publishing Environment
  36 #      (http://www.zope.org/)."
  37 #
  38 #    In the event that the product being advertised includes an
  39 #    intact Zope distribution (with copyright and license included)
  40 #    then this clause is waived.
  41 #
  42 # 5. Names associated with Zope or Digital Creations must not be used to
  43 #    endorse or promote products derived from this software without
  44 #    prior written permission from Digital Creations.

  46 # 6. Modified redistributions of any form whatsoever must retain
  47 #    the following acknowledgment:
  48 #
  49 #      "This product includes software developed by Digital Creations
  50 #      for use in the Z Object Publishing Environment
  51 #      (http://www.zope.org/)."
  52 #
  53 #    Intact (re-)distributions of any official Zope release do not
  54 #    require an external acknowledgement.
  55 #
  56 # 7. Modifications are encouraged but must be packaged separately as
  57 #    patches to official Zope releases.  Distributions that do not
  58 #    clearly separate the patches from the original work must be clearly
  59 #    labeled as unofficial distributions.  Modifications which do not
  60 #    carry the name Zope may be packaged in any form, as long as they
  61 #    conform to all of the clauses above.
