I'm having the worst time trying to center chapter headings that are
split over two lines.  The style file I'm using for my thesis has the
following definitions for chapter headings:


\def\@makechapterhead#1{{ \parindent 0pt
 \ifnum \c@secnumdepth >\m@ne
 \centerline{\large\bf \@chapapp{} \thechapter}
 \par
 \vskip 20pt \fi \centerline{\Large \bf #1}\par
 \nobreak \vskip 40pt } }

\def\@makeschapterhead#1{{ \parindent 0pt
 \centerline{\Large\bf #1}\par
 \nobreak \vskip 40pt } }


The problem is that the \centerline{} doesn't split lines.  I've tried
replacing \centerline{...} with {\centering ...}.  This will center the
the first line, however, the second line is left justified.  HELP!
There has got to be a way to center long chapter headings.  I would be
happy to summarize the responses that I recieve if people would like.

Thank you
