Hi Jim.  I've implemented an alternative fix for this in SVN; use:

    easy_install svn://svn.eby-sarna.com/svnroot/DecoratorTools/

to update.  The change is that instead of a docstring or function 
attribute, I use the template function's return value.  There's also 
an improved error message for the case where someone's still using 
the docstring approach and you're running -OO.

Please let me know if this update works for you; I'd like to get some 
feedback before cutting an official release on PyPI.  Thanks.
