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. For more information, see: http://www.zope.org/Resources/License Jim -- Jim Fulton mailto:jim@zope.com Python Powered!
