What is PyProtocols?
--------------------

PyProtocols is an extended implementation of PEP 246, adding a new 
"declaration  API" that lets you easily define your own interfaces and 
adapters, and declare what adapters should be used to adapt what types, 
objects, or interfaces.  Using PyProtocols, you can easily make flexible 
frameworks that you or other developers can extend without needing to 
modify the base framework.  PyProtocols interfaces can interoperate with 
those of Twisted and Zope, or can be used entirely standalone.

PyProtocols may be used, modified, and distributed under the same terms
and conditions as Python or Zope.


What's new in version 0.9.1?
----------------------------

* Implemented Samuele Pedroni's "subproto" idea (see 
http://mail.python.org/pipermail/python-dev/2003-June/036242.html) as the 
new 'protocolForType()' API.

* Added other APIs to automatically generate protocols, such as 
'protocolForURI()', 'sequenceOf()', and 'Variation()'.

* Compatible with Zope X3 Milestone 4, Python 2.3.2, and Twisted 
1.1.0.  (Also runs on Python 2.2.2+, if you don't need Zope 3 compatibility.)

* New 'Adapter' and 'StickyAdapter' convenience base classes

* Fixes for compatibility with 'ExtensionClass', and for a memory leak in 
the optional C "speedups" module
