+% 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 
+% 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.

+% License, as described in lppl.txt in the base LaTeX distribution.
+% Either version 1 or, at your option, any later version.
+% ========================================================================
+% MODIFICATION HISTORY:
+% Sep 16, 1994
+% version 1.4: Correction for use with \reversemargin
+% Sep 29, 1994:
+% version 1.5: Added the \iftopfloat, \ifbotfloat and \iffloatpage commands
+% Oct 4, 1994:
+% version 1.6: Reset single spacing in headers/footers for use with
+% setspace.sty or doublespace.sty
+% Oct 4, 1994:
+% version 1.7: changed \let\@mkboth\markboth to
+% \def\@mkboth{\protect\markboth} to make it more robust
+% Dec 5, 1994:
+% version 1.8: corrections for amsbook/amsart: define \@chapapp and (more
+% importantly) use the \chapter/sectionmark definitions from ps@headings if
+% they exist (which should be true for all standard classes).
+% May 31, 1995:
+% version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage...
+% construction in the doc did not work properly with the fancyplain style. 
+% June 1, 1995:
+% version 1.91: The definition of \@mkboth wasn't restored on subsequent
+% \pagestyle{fancy}'s.
+% June 1, 1995:
+% version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain}
+% \pagestyle{fancy} would erroneously select the plain version.
+% June 1, 1995:
+% version 1.93: \fancypagestyle command added.
+% Dec 11, 1995:
+% version 1.94: suggested by Conrad Hughes <chughes@maths.tcd.ie>
+% CJCH, Dec 11, 1995: added \footruleskip to allow control over footrule
+% position (old hardcoded value of .3\normalbaselineskip is far too high
+% when used with very small footer fonts).
+% Jan 31, 1996:
+% version 1.95: call \@normalsize in the reset code if that is defined,
+% otherwise \normalsize.
+% this is to solve a problem with ucthesis.cls, as this doesn't
+% define \@currsize. Unfortunately for latex209 calling \normalsize doesn't
+% work as this is optimized to do very little, so there \@normalsize should
+% be called. Hopefully this code works for all versions of LaTeX known to
+% mankind.  
+% April 25, 1996:
+% version 1.96: initialize \headwidth to a magic (negative) value to catch
+% most common cases that people change it before calling \pagestyle{fancy}.
+% Note it can't be initialized when reading in this file, because
+% \textwidth could be changed afterwards. This is quite probable.
+% We also switch to \MakeUppercase rather than \uppercase and introduce a
+% \nouppercase command for use in headers. and footers.
+% May 3, 1996:
+% version 1.97: Two changes:
+% 1. Undo the change in version 1.8 (using the pagestyle{headings} defaults
+% for the chapter and section marks. The current version of amsbook and
+% amsart classes don't seem to need them anymore. Moreover the standard
+% latex classes don't use \markboth if twoside isn't selected, and this is
+% confusing as \leftmark doesn't work as expected.
+% 2. include a call to \ps@empty in ps@@fancy. This is to solve a problem
+% in the amsbook and amsart classes, that make global changes to \topskip,
+% which are reset in \ps@empty. Hopefully this doesn't break other things.
+% May 7, 1996:
+% version 1.98:
+% Added % after the line  \def\nouppercase
+% May 7, 1996:
+% version 1.99: This is the alpha version of fancyhdr 2.0
+% Introduced the new commands \fancyhead, \fancyfoot, and \fancyhf.
+% Changed \headrulewidth, \footrulewidth, \footruleskip to
+% macros rather than length parameters, In this way they can be
+% conditionalized and they don't consume length registers. There is no need
+% to have them as length registers unless you want to do calculations with
+% them, which is unlikely. Note that this may make some uses of them
+% incompatible (i.e. if you have a file that uses \setlength or \xxxx=)
+% May 10, 1996:
+% version 1.99a:
+% Added a few more % signs
+% May 10, 1996:
+% version 1.99b:
+% Changed the syntax of \f@nfor to be resistent to catcode changes of :=
+% Removed the [1] from the defs of \lhead etc. because the parameter is
+% consumed by the \@[xy]lhead etc. macros.
+% June 24, 1997:
+% version 1.99c:
+% corrected \nouppercase to also include the protected form of \MakeUppercase
+% \global added to manipulation of \headwidth.
+% \iffootnote command added.
+% Some comments added about \@fancyhead and \@fancyfoot.
+% Aug 24, 1998
+% version 1.99d
+% Changed the default \ps@empty to \ps@@empty in order to allow
+% \fancypagestyle{empty} redefinition.
+% Oct 11, 2000
+% version 2.0
+% Added LPPL license clause.
+%
+% A check for \headheight is added. An errormessage is given (once) if the
+% header is too large. Empty headers don't generate the error even if
+% \headheight is very small or even 0pt. 
+% Warning added for the use of 'E' option when twoside option is not used.
+% In this case the 'E' fields will never be used.
+%
+% Mar 10, 2002
+% version 2.1beta
+% New command: \fancyhfoffset[place]{length}
+% defines offsets to be applied to the header/footer to let it stick into
+% the margins (if length > 0).
+% place is like in fancyhead, except that only E,O,L,R can be used.
+% This replaces the old calculation based on \headwidth and the marginpar
+% area.
+% \headwidth will be dynamically calculated in the headers/footers when
+% this is used.
+%
+% Mar 26, 2002
+% version 2.1beta2
+% \fancyhfoffset now also takes h,f as possible letters in the argument to
+% allow the header and footer widths to be different.
+% New commands \fancyheadoffset and \fancyfootoffset added comparable to
+% \fancyhead and \fancyfoot.
+% Errormessages and warnings have been made more informative.
+%
+% Dec 9, 2002
+% version 2.1
+% The defaults for \footrulewidth, \plainheadrulewidth and
+% \plainfootrulewidth are changed from \z@skip to 0pt. In this way when
+% someone inadvertantly uses \setlength to change any of these, the value
+% of \z@skip will not be changed, rather an errormessage will be given.
