%
% version 2.3      Modified \@startsection,\@sect,\@seccntformat included
% 20 July 1996     for LaTeX2e compatibilty mode.  Fixed a bug in .aux
%                  file output.  Now detects OFSS/NFSS.  Times font can be
%                  loaded through "times" documentstyle option if 
%                  LaTeX2e installation with "times.sty" is available.
%
% release 2.2      Small adjustments in footnote skip, footnote rule, 
% 03 July 1996     float top and bottom glue.
%
% release 2.1      Side margins modified (01 July '96)
%
% release 2.0      Set in 11 point instead of 10 point style.  Corrected
% 22 June 1996     minor formatting discrepancies.  Times fonts now 
%                  loaded through customized jplain.fmt.  "plate"
%                  option abolished.
%
% release 1.1      Included "plate" option and Times Roman fonts.
% 18 June 1996     Will need jaa_press.tex to be included in the
%                  document to be processed for the Times fonts to
%                  take effect.  Without plate option normal cmr
%                  fonts will be used.  "plate" option should be
%                  used only at the JAA editorial office.
%
% release 1.0      First release of basic `jaa' style,  Including
% 15 June 1996     documentstyle options "doublespacing" and 
%                  "landscape".  Page styles, Abstract and Keywords
