OK, since I don't have any use for xml-catalog, I've no problem if this is
implementation detail. But I'm not sure what "Jam variables" mean. The
general V2 approach is to avoid variables as much as possible. For
example, to configure gcc, you might say

using gcc : 3.2 g++-3.2 ;

instead of setting any variables directly. Probable this wouls be good for
BookBook as well.

Ok, let's see how this will work.
