I'm trying to modify the boxedminipage.sty style file so that I can get a
boxed minipage with a title on it, of the form:

	--- Title --------------------------------------------------------
	|    text goes here ... blah blah blah                           |
	------------------------------------------------------------------

What I've done is changed the initial \hrule\@height\fboxrule statement
that draws the top rule into an hbox containing three other hboxes:

   \hbox{\hbox to 0.25in{\hrulefill}\hbox{Title}\hbox to \@brule{\hrulefill}}

where \@brule is the width of the title.  This works fine, except that there
is now a small gap between where the top rule joins the two vertical rules.
I've tried several things, including \vskip-\lastskip but nothing seems to
work -- I always get the gap.  Any clues as to what I should be doing?

BTW, this is the full code for boxedminipage.sty, in case others might
find it useful.  I think I got if off of clarkson...

--------------------------- boxedminipage.sty ------------------------------

%	boxedminipage.sty
%
% adds the boxedminipage environment---just like minipage, but has a
% box round it!
%
% The thickneess 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!
