Differences between Kid and Genshi

* Genshi directly interprets templates (unlike Kid, which generates Python code) * Genshi uses XInclude for template reuse * Genshi adds attributes Kid does not have, like py:choose * Genshi templates are easier to debug, because it tracks template source file names and line numbers, and errors from Genshi's interpreter produce more comprehensible stack traces than from Kid's generated code.
