% History of v1.0 (actually not 1.0)
% ~~~~~~~~~~~~~~~
% 99/11/03: Split from titlesec.sty
% 99/11/03: Changed \setmarks, \ttl@sethead, \ttl@setfoot to follow
%           the new scheme
% 99/11/03: Removed the redefinition of \markboth. The arguments are
%           expanded on the fly by the corresponding \...mark. 
% 00/01/06: Added the \newtitlemark device.
% 00/01/19: Rejected the idea of a separate package (for the time 
%           being). Now it's ttlps.def.
% 00/01/20: Starred versions of \widenhead, \sethead, \setfoot.
% 00/01/23: Added \ifthe..., \iftitle, etc.
% 00/02/05: Modified \ifthe... mechanism
% 00/02/25: Fixed a bug which made enter in an endless loop.
%           Now \ttl@marks is just \relax. The new scheme made
%           compatible with babel. (2.3.1)
% 00/03/01: Fixed a bug in the previous bug fix. (2.3.2)
% 00/03/08: Removed the code for AMS and babel. A general procedure
%           to catch the changes of \markboth is introduced, with
%           \ttl@enccode and \ttl@running. (2.3.3)
% 00/05/05: \setmarks may be used outside of \newpagestyle, with
%           the help of \ttl@setmarks and \ttl@marksset (2.3.4)
% 00/05/25: Tests for \ttl@toclabel moved to the redefinition of
%           \secdef in titlesec. (2.3.5)
% 00/06/07: Added the first attempt for pagestyles with floats.
%           With slight changes, it will become the final form
%           for that. (2.3.5)
% 00/06/14: The default \ifthe... are now defined with \ttl@setifthe
%           so that they are robust from the very beginning. (2.3.5)
% 01/01/21: Replaced some \defs by \newcommand
% 10/12/03: A little addition to the warning, for those who don't
%           read the docs.
%
% History of v1.1
% ~~~~~~~~~~~~~~~
% 11/11/26: Add the extra mark mechanim
% 11/12/07: Enlarged, eg, multilevel \newtitlemark, \newtitlemark*,
%           premarks
%
% As before, all marks has two parts but now they don't refer to left or 
% right pages at all.  There are some issues related to top marks which 
% are explained by Knuth in \textit{The \TeX book}, pp.  259f, as well 
% as an uncompatibility between them and \LaTeX{} floats.  To overcome 
% both limitations, in the \textsf{titlesec} page styles, the second 
% part in |\cs{firstmark}| is a \emph{fixed} top mark and the first one 
% the actual first mark; the right way to get the bot mark is from the 
% second part.  Marks are stored at each section and used before and 
% after the title (straight class); the first part contains the values 
% of current title, but the second one contains the previolusly stored 
% values in the mark before the title, and the current values in the 
% mark after.
