[Grok-dev] Accessing a METAL template from another template

[Sebastian Ware]

I managed to get it to work. The issue might have been that I put  
[metal:use-macro] before [metal:define-macro], but I am not sure  
because I have changed the source too many times.

Anyway, this mistake might be worth mentioning too. The wierd thing is  
that if you switch after you have rendered the page once with the  
statements in the correct order (define-macro before use-macro) and  
then render the page again without a restart, it works. But once you  
restart Zope, you get an error... switch the statements and it  
works... switch them again, and it still works... restart... error...
