[tor-relays] How to include files into torrc?

Hello, is it possible to include files into torrc? Something like this: # /etc/tor/torrc ORPort 443 # Policies are kept in separate file for readability Include /etc/tor/policies I checked https://www.torproject.org/docs/tor-manual.html.en but could not find anything. As an alternative, one can of course generate torrc from other files, but I'd rather use an include feature, if available. -Ralph
