Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    [sboxes]: Skip macro package instead of aborting.
    
    * sboxes.tmac: Skip macro package instead of aborting if there are
      prerequisite problems.  This is an auxiliary package; it is not
      necessarily fatal to the user's purposes if it doesn't load.
