--- BEGIN ISSUE ---
Support addtional regions in CloudSearch 
It appears that boto currently only supports two regions. It would be nice to support the more recently added ones. 

Current list of CloudSearch regions is here: http://aws.amazon.com/cloudsearch/faqs/#Which_AWS_regions_is_CloudSearch_available_in?

I think it just needs to be added to boto/cloudsearch/**init**.py:

return [RegionInfo(name='us-east-1',
                       endpoint='cloudsearch.us-east-1.amazonaws.com',
                       connection_cls=boto.cloudsearch.layer1.Layer1),
            RegionInfo(name='eu-west-1',
                       endpoint='cloudsearch.eu-west-1.amazonaws.com',
                       connection_cls=boto.cloudsearch.layer1.Layer1),

And yes, you can use another region by changing the default field in .boto
