---------------

      This 'Employee' class shows how methods can use other Zope
      objects to weave together relational data to make it seem like a
      collection of objects. The 'manager' method calls two Z SQL
      Methods, one to figure out the emp_id of the employee's manager,
      and another to return a new Result object representing the
      manager. You can now treat employee objects as though they have
      simple references to their manager objects. For example you
      could add something like this to the *viewEmployee* DTML Method::

        <dtml-if manager>
          <dtml-with manager>
            <p> My manager is <dtml-var first> <dtml-var last>.</p>
          </dtml-with>
        </dtml-if>
