How can I make a namespace of the form:
<%namespace name="foo" module="foo.bar" />
available to all of the templates in my project by default; so rather than each template having to include the above line at the start it is just done automatically by mako. I have looked at the Template and TemplateLookup class documentation but there does not seem to be an easy way of doing this.
You can combine inheritance with Inheritable Namespaces to achieve what you want.
