Hi, I wrote (yet another) templating language for Python based on Genshi, since Genshi itself does not yet work on Google App Engine (GAE). Since Genshi supports XPath I was thinking about using your cssselect.py module together with it. First tests showed that this seems to work fine. Now I would like to ship a little bit modified version of cssselect.py with this new templating language called "Pyxer" http://code.google.com/p/pyxer/ so the users do not have to install the whole lxml package (which does not work with GAE anyways I suppose). Since Python "lxml" is under the BSD license and Pyxer under MIT license I think this should not be such a big problem as long as I add your copyright notices to the file. Am I right? Thanks for your excellent work Dirk
