python-protocols 1.0a0dev-4 (powerpc binary) in ubuntu feisty

 Do you hate having to write lots of if-then logic to test what type
 something is? Wouldn't it be nice if you could just declare "I want
 this object to have this behavior" and magically convert whatever
 value you have, to the type you need? PyProtocols lets you do just
 that, cleanly, quickly, and robustly -- even with built-in types or
 other people's classes.
 .
 PyProtocols extends the PEP 246 adapt() function with a new
 "declaration API" that lets you easily define your own protocols and
 adapters, and declare what adapters should be used to adapt what
 types, objects, or protocols. In addition to its own Interface type,
 PyProtocols can also use Twisted and Zope's Interface types too. (Of
 course, since Twisted and Zope interfaces aren't as flexible, only a
 subset of the PyProtocols API works with them. Specific limitations
 are listed in the documentation.)
