[Bro] "services" variable referenced in known-services.bro

I'm using known-services to build a list of observed network conversations and the protocols being used.  Known-services detects the TCP conversations, but I want to include UDP conversations as well.  Known-services.bro seems to use a global variable, "services"; services, however, does not hold UDP conversation protocol labels.  I've searched for the script that populates "services", to no avail.

Where do I find that script?  Alternatively, is there a better way to build an all-inclusive conversation vs. protocol mapping?
