You're adding a .tmpl extension to the template files.
I think it's better to leave these files as is.

While I understand the motivation, AFAICT Jinja templates
generally use the usual extension:
"A template is simply a text file. It can generate any text-based format (HTML,
XML, CSV, LaTeX, etc.). It doesn’t have a specific extension, .html or .xml are
just fine."
http://jinja.pocoo.org/docs/templates/

If you want syntax highlighting (which is going to be tricky),
there is some code here:
http://jinja.pocoo.org/docs/integration/
...but it looks like we'll have to wrap our own if we want
C++ and Jinja.
