	--| FIXME This version has been commented, so that we do not need to have
	--| all the interface classes shipped with Build2. The user does not need to know about these
	--| classes and how they work.
	--| The nice thing about having it done this way, is that when a new class is defined, the system
	--| will just work, where as when we are using the above version, it must be updated manually.
