[Christophe de Vienne (cdevienne)]

Hi,

The example is missing a "config.include('wsmeext.cornice')".

See test/test_cornice.py for a working example.

A patch for the documentation would be very welcome.

Cheers,

Christophe

Hi, Christophe,

Yes, I just tried to add missing statement in __init__.py does fix the problem.

I could help to up date the document if needed.

Thanks,
Yapeng
