hobbit-alerts config and PAGE definition

How does the syntax work in the hobbit-alerts.cfg for the PAGE directive
if multiple pages are to be defined?

In our environment, the bb-hosts file contains an entry for itself
followed by x number of "include" lines. Each included file then contains
some number of "page" directives. I don't think PAGE=/ will work here.
What would be the right to define

	PAGE=pagea,pageb,pagec
