%%% this:

%%%
%%% The length variable \captionwidth controls
%%% how the caption is typeset. If the width
%%% of the caption is less than \captionwidth,
%%% the \hangcaption is typeset the same way a
%%% short \caption would be (usually centered).
%%% Otherwise, it is set as shown above, with a
%%% total width equal to \captionwidth.
%%% \captionwidth is set to \hsize normally,
%%% but you may want to change it temporarily
%%% to match the width of a \tabular*
%%% environment, for example.
%%%
%%% \hangcaption is used in the same way as
%%% \caption. To retain compatibility with
%%% previous versions of this style, the
%%% \hangcaption is also available under the
%%% name \isucaption.
%%%
%%% I did not write this file. The original
%%% author is unknown. However, I did fix a bug,
%%% namely, I removed a superflous "^^" that was
%%% causing one of the close braces to be
%%% interpreted as an equals sign, thus messing
%%% up the brace balancing. I also tacked an
%%% "\endinput" on to the end of the file and
%%% added this header, and incorporated a few
%%% changes suggested by Harm Bakker, George
%%% Greenwade, and Rainer Schoepf.
%%%
%%% v2.00 (27 Aug 1992): altered \numberline to
%%% use \the... instead of \fnum@... (fix due to
%%% Harm Bakker <bakker@cs.rulimburg.nl>).
%%% Changed \isucaption to \hangcaption at George
%%% Greenwade's <bed_gdg@SHSU.edu> suggestion.
%%%
%%% v1.03 (12 August 1992): minor changes to
%%% header.
%%%
%%% v1.02 (12 August 1992): patches by Rainer
%%% Schoepf <schoepf@sc.ZIB-Berlin.DE> to (a)
%%% work around a bug in LaTeX and (b) measure
%%% the caption correctly by including room for
%%% the colon and the space.
