I'm thinking we may need to go to a matrix build because I don't want to test against py3.5-dev, especially since Mako is particularly sensitive to changes in core python.

Something like this would be better, and a tox.ini to match:

I haven't really had a chance to bring this repo in line with all the other changes we've been making to the Pylons Project repositories in terms of testing...

I have never set up tox, but I'm willing to give it a try. Or is it better if I wait for you to do that? The reason I wanted to set up travis is the issue I just had with pyramid_mako and the way it some how messes up calls to request.static_url() if I link to relative static assets from within the template, see here

I've added a .travis.yml and updated tox.ini.
