  % The macro is called with commands in #1 that manipulates
  % the box \mybox. These commands along with the result of
  % the manipulation is shown. Thus the essence of the
  % macro is:
  %
  %   a) \sbox{\mybox}{The cracy fox.}
  %   b) #1 % manipulates \mybox
  %   c) Print #1 commands.
  %   d) Print box with frame
