Configuration of own roles in external file?

[Stephan Coboos]

Hello,

long long time ago I had heard that own roles can be configured in a 
separate config file. But I have forgotten which structure this file 
must have and how to set the path to this file. The only thing I know is 
there was an attribuite in <cocoon/> of cocoon.xconf to set the path, 
but which? Maybe roles="..." ?

Thank you.

Regards
