ActionMap was the thing I designed that was supposed to handle this --
you can create one "foo" and then every path that begins with /foo/
will use that.

The other way I have done this is to put the logic on the "missing"
page.

Maybe, if it gets fleshed out a bit.

GlobalSub goes anywhere in interchange.cfg and its includes. You would
want something like:

	foreach (@foobar) {
	    if(/^\w+$/) {
		$cr = $Vend::Cfg->{Sub}{$_} || $Global::GlobalSub->{$_};
	    }
	    else {
		$cr = \&{$_};
	    }

	    if (! defined $cr) {
		logGlobal("Undefined PageResolution routine '%s', $_);
		return undef;
	    } 
	    ....
	}
