[Zope-Annce] Announce: Reusable Zope Public License 2.1

[Jim Fulton]

We have updated the Zope Public License (ZPL) to revision 2.1. ZPL 2.1
is reusable. It supports having a consistent license for Zope and
third-party products without requiring 3rd-party developers to assign
copyright to Zope Corporation.

It is important that add-on products for Zope be released under the
ZPL. Why? Two reasons:

     * The ZPL is a flexible license that supports both commercial and
       non-commercial use of the software.

     * If Zope add-on products are released under the ZPL, then users
       of Zope and the add-on products only have one license to worry
       about. Keeping track of many different licenses is a burden to
       users.
