%
% The thickness of the rules around the box is controlled by
% \fboxrule, and the distance between the rules and the edges of the
% inner box is governed by \fboxsep.
%
% This code is based on Lamport's minipage code.
%
% Fixed, 7 Jun 89 by Jerry Leichter
%	Leave \fboxsep worth of separation at top and bottom, not just at
%	the sides!
