%  Tables of contents

%  The original versions of the table of contents entries justify long
%  headings, which gives spaced out text which looks awful.  We change
%  this to typeset headings \raggedright instead.  We also use lightface
%  rather than bold, and decrease the skip between entries, since
%  TUGboat contents lists usually don't go to levels below \section.
%
%  Modifications mainly by Nelson Beebe, with indentation to make macros
%  more readable.

Version   Date        Changes
-------   ---------   ---------------------------------------------------
1.19      16 Nov 93   added new t-of-c definitions, based on modifications by
                        Nelson Beebe; make text ragged right, lightface, and
                        entries closer together than latex.tex default

1.18b      8 Nov 93   removed extraneous " from header

1.18a     29 May 93   changed \family to \fontfamily in defs of \tensl, \tenuit
                      within \sectitlefont, define \La to get proper "A"

1.18      22 Mar 93   added \hyphenpenalty=10000 to (sub*)section headings
                      added missing brace at end of \def\tensl for nfss
                      added new environments \dedication and \longabstract

1.17      19 Feb 93   incorporated some font definitions by Rainer Schoepf
                        to add flexibility when used under NFSS
