% LICENCE:
% This file may be distributed under the terms of the LaTeX Project Public
% License, as described in lppl.txt in the base LaTeX distribution.
% Either version 1 or, at your option, any later version.
% ========================================================================
% MODIFICATION HISTORY:
% Oct 11, 2000
% version 1.99e
% Added a few % marks to get rid of unwanted spaces, and \endinput.
% Added LPPL license clause.
% March 12, 2002
% version 2.0beta
% Adapted for the new implementation of marks in LaTeX to solve bug
% latex/3203.
% Added symmetric commands \firstrightmark, \lastleftmark, \firstleftxmark,
% \firstrightxmark, \lastrightxmark, \lastleftxmark, \topleftxmark and
% \toprightxmark.
% March 3, 2004
% version 2.0
% Release.
% This package gives you two additional marks.
% \extramarks{m1}{m2} define two extra marks for headers/footers
% (especially for use with fancyheadings), which can be retrieved
% by \firstxmark and \lastxmark resp. Usually m1 is what would
% appear at the top of the page, m2 at the bottom of the page.
% Typical usage:
% \pagestyle{fancy}
% \lhead{\firstxmark}
% \rfoot{\lastxmark}
%
% \extramarks{}{Continued on next page...}

% text text text text text text text text text text text text text text text
% text text text text text text text text text text text text text text text
% \extramarks{Continued}{}
% \extramarks{}{}
% This package also provides two extra handles to the standard LaTeX marks,
% namely \firstleftmark and \lastrightmark (the standard \leftmark and
% \rightmark of LaTeX always give you the last and first, respectively.
% These are the complementary values). For symmetry reasons \firstrightmark
% is an alias for \rightmark and \lastleftmark is an alias for \leftmark
% Similarly there are now \firstleftxmark \firstrightxmark \lastrightxmark
% \lastleftxmark. Here first and last apply to the position on the page,
% left and right select the m1 and m2 values, respectively.
% Note: there is an extra command \topxmark, but this doesn't work properly
% if marginpars or floats are used, as LaTeX clobbers TeX's topmark in this
% case.
\newtoks\@temptokenb
%Just in case.
