[mkgmap-dev] Routing parameters

Yes, as you can see above, I  understand the intent of those two options.
But if someone could further explain what's happening in the rule, I would
be most appreciative.

I'm guessing the first part assigns a name or ref if one appears in the
tagging but understanding the logic of the series of "subst" filters
following that is, for a newbie, quite challenging.
