+% \textbf{Note:} This section only applies to \Package{fancyhdr} version~4.0
+% and later\footnote{This comes from the \Package{nccfancyhdr}
+% package by Alexander I. Rozhenko.}.
+%
+% The marks in a fancy header and footer are prepared using \cs{parbox}
+% command. So, you can use multiline marks. In the header, they are
+% aligned to the bottom line, but, in the footer, they are aligned to
+% the top line. The maximum width of every mark is equal to the
+% \cs{headwidth}. This can lead to overlapping of neighbouring marks.
+%
+% \DescribeMacro{\fancycenter}
+% If you want to prepare marks in more traditional way in a line
+% not exceeding the \cs{headwidth}, you can use
+% the following command in any mark command:
+% \begin{quote}
+% \cs{fancycenter}\oarg{distance}\oarg{stretch}\\
+% \verb| |\marg{left-mark}\marg{center-mark}\marg{right-mark}
+% \end{quote}
+% This command works like
+% \begin{center}
+% \verb|\hbox to\linewidth{|\marg{left-mark}\cs{hfil}\marg{center-mark}\cs{hfil}\marg{right-mark}\verb|}|
+% \end{center}
+% but does this more carefully trying to exactly center the central part of
+% the text if possible. The solution for exact centering
+% is applied if the width of \meta{center-mark} is less than
+% \begin{quote}
+% \verb|\linewidth - 2*(|\meta{stretch}\verb|*|\meta{distance}\verb| +|\\
+% \verb| max(width(|\meta{left-mark}\verb|), width(|\meta{right-mark}\verb|)))|.
+% \end{quote}
+% Otherwise the \meta{center-mark} will slightly migrate to a shorter item
+% (\meta{left-mark} or \meta{right-mark}), but at least \meta{distance}
+% space between all parts of line is provided.
+% The default values of \meta{distance} and \meta{stretch}
+% are 1em and 3.
+%
+% If the \meta{center-mark} is empty, the \cs{fancycenter} is equivalent to
+% the following command:
+% \begin{center}
+% \verb|\hbox to\linewidth {|\marg{left-mark}\verb|\hfil |\marg{right-mark}\verb|}|
+% \end{center}
+%
+% You would use this in a header for example with
+% \begin{quote}
+% \verb|\fancyhead[C]{|\cs{fancycenter}\oarg{distance}\oarg{stretch}\\
+% \verb| |\marg{left-mark}\marg{center-mark}\marg{right-mark}\verb|}|
+% \end{quote}
+% and leave the \texttt{[L,R]} parts empty.
+%
+% \textbf{Note 1}: If the whole of the \cs{fancycenter} is wider than
+% \cs{headheight} it will stick out on the right. See
+% section~\ref{sec:longtitles} for possible solutions.
+%
+% \textbf{Note 2}: The usage of \cs{fancycenter} command is not limited to the
+% argument of header/footer marks. You can use it anywhere in your document.

+% \section{Defining other page styles}
+% \label{sec:fancypagestyle}
+%
+% Just like redefining the \texttt{plain} page style in the previous
+% section, you can define or redefine other page styles based on page
+% style \texttt{fancy}. This is also done with the \cs{fancypagestyle}
+% command. The general form of this command is:
+% \begin{quote}
+% \CmdIndex{fancypagestyle}
+% \verb|\fancypagestyle|\marg{style-name}\oarg{base-style}\marg{definitions}
+% \end{quote}
+% As you see, there is an optional argument between the two mandatory arguments.
+%
+% For example:
+% \begin{verbatim}
+% \fancypagestyle{toc}{%
+% \fancyhf{}%
+% \fancyhead[RO]{\thepage}%
+% \fancyhead[RO]{\textsl{TABLE OF CONTENTS}}%
+% \fancyfoot[C]{\thepage}
+% }
+% \end{verbatim}
+% This defines a special page style \texttt{toc} for use in the table
+% of contents with \Cmd{pagestyle\{toc\}}.
+% Inside the definition you can define the headers and/or footers,
+% change the header and footer rules, and redefine commands like
+% \cs{chaptermark} (see section~\ref{sec:options} for an example). The
+% headers and footers and marks that are not redefined inside the
+% \cs{fancypagestyle} definition, are taken from the global page style
+% \texttt{fancy} values.
+%
+% You can also give an optional base page style to the
+% \cs{fancypagestyle} command. Then the new page style will be based on
+% the base style. This base style must be a \texttt{fancyhdr}-defined
+% style. Also you should take care not to
+% create circular dependencies. In this case the order of picking up the
+% definitions (headers, footers, marks) is:
+% \begin{enumerate}
+% \item The definitions from the base style are taken.
+% \item The definitions given in the \cs{fancypagestyle} command
+% override and/or augment these.
+% \item Any definitions that are not given by the two above, are taken
+% from the environment at the time the new page style is used.
+% \end{enumerate}
+% Only the first two parts are embedded in the page style.
+% When no base style is given, part 1 is null.
+%
+% The optional base style argument is only available since version~4.0. In
+% this version it is also possible to redefine page style \texttt{fancy}
+% in this way. In version~3.x and earlier this was not possible.
+%
+% If you want to restore the original default definitions
+% from page style \texttt{fancy} as described in section~\ref{sec:default}, you can use
+% \begin{verbatim}
+% \fancypagestyle{myfancy}[fancydefault]{
+% . . . override some here
+% }
+% \end{verbatim}
+% \PSindex{fancydefault}
+% Page style \texttt{fancydefault} is the version of page style
+% \texttt{fancy} that has all the initialisation embedded. Contrary to
+% this, page style \texttt{fancy} as defined in the package uses the
+% same defaults, but doesn't have them embedded. It picks them up from
+% the environment. So if the environment changes, because you redefine
+% headers, footers, mark commands, etc, the functioning of page style
+% \texttt{fancy} changes with it. The page style \texttt{fancydefault}
+% does not change, however. However, \texttt{fancydefault} is only available
+% since fancyhdr version~4.0.
+%
+% \section{Package options}
+% \label{sec:options}
+%
+% \textbf{NOTE:} This section applies to fancyhdr version~4.0 and later.
+%
+% You can supply options to the \cs{usepackage} command:
+% \begin{quote}
+% \verb|\usepackage|\oarg{options}|{fancyhdr}|
+% \end{quote}
+% % The following options are supported:
+% \begin{center}
+% \OPTindex{nocheck}\OPTindex{compatV3}\OPTindex{headings}\OPTindex{myheadings}
+% \begin{tabular}{ l l }
+% \toprule
+% Option & Meaning \\
+% \midrule
+% \texttt{nocheck} & do not check the heights of the header and footer \\
+% \texttt{compatV3} & keep some behaviour (now considered undesirable) as in version~3 \\
+% \texttt{headings} & redefine the \texttt{headings} page style to be fancy-based \\
+% \texttt{myheadings} & redefine the \texttt{myheadings} page style to be fancy-based \\
+% \bottomrule
+% \end{tabular}
+% \end{center}
+%
+% \begin{itemize}
+% \item \OPTindex{nocheck}Option \texttt{nocheck} is described in section~\ref{sec:warning} on
+% page~\pageref{page:warning}.
+%
+% \item \OPTindex{compatV3}Option \texttt{compatV3} keeps two fancyhdr
+% version~3.x (or earlier) features that are now considered undesirable.
+% \begin{enumerate}
+% \item The automatic adjustment of \cs{headheight} or \cs{footskip}
+% when these are too small. This causes the page layout to become
+% inconsistent. See section~\ref{sec:warning} on
+% page~\pageref{page:warning}.
+% \item In these previous versions the changes to the
+% \Package{fancyhdr} headers and footers (including those by
+% \cs{fancyhead}, \cs{fancyheadoffset} and similar commands) are
+% made globally, except within a page style defined by
+% \cs{fancypagestyle}. That is, when these commands are given inside
+% a \LaTeX{} group, they affect the whole document, not only the
+% group. If your document depends on this behaviour, you can give
+% the \texttt{compatV3} package option. However, this is only
+% considered a short-time solution. You should change your document
+% as soon as possible to work around this problem. In version~4.0 and
+% later, without this option, the changes are always local.
+% \end{enumerate}
+% The option is scheduled to disappear in version~5 of
+% \Package{fancyhdr}.
+%
+% \item \PSindex{headings}\PSindex{myheadings}\OPTindex{headings}\OPTindex{myheadings}
+% The options \texttt{headings} and \texttt{myheadings} redefine the
+% corresponding page style with fancyhdr commands (including a
+% decorative line under the header), so that you can later select this
+% page style as the page style for (part of) the
+% document\footnote{These options were copied from the
+% \texttt{nccfancyhdr} package, but contrary to that package, they are
+% not automatically selected.}.
+% \end{itemize}
+%
+% \PSindex{headings}
+% The page style \texttt{headings} is in some aspects similar to the default page
+% style \texttt{fancy} settings. In the \texttt{fancy} page style, the
+% page number is in the footer, but in the \texttt{headings}
+% page style it is in the header. The header fields look similar, however.
+%
+% Please note that these page styles redefine the \cs{chaptermark} and/or
+% \cs{[sub]sectionmark} commands (see section~\ref{sec:scoop}), as do the
+% standard \latex/ page styles. The consequence is, that if you select
+% e.g.\ \Cmd{pagestyle\{headings\}}, the definitions of
+% \Cmd{pagestyle\{fancy\}} are overridden.
+% Also when you change the headers and/or footers
+% while such a page style is in effect, and you then switch back to this
+% page style, for
+% example with \verb|\pagestyle{headings}|, they revert to the built-in
+% settings. Therefore it is not advisable to change the headers or
+% footers in this way, but instead define your
+% own page style, as explained in section~\ref{sec:fancypagestyle}.

+% Page style \texttt{fancy}, if not redefined, does not have the definitions of the
+% headers and footers built-in, but they are defined in the document,
+% globally, or locally in a group. This also applies to the definitions of the
+% \cs{chaptermark} and/or \cs{[sub]sectionmark} commands. So if you want
+% to switch from another page style to the \texttt{fancy} page style
+% later in the document, and that other page style has changed for
+% example the \cs{chaptermark} and/or \cs{[sub]sectionmark} commands,
+% you will have to redefine these yourself and maybe also
+% the definitions of the headers and footers, at that point.
+% For example
+% \begin{verbatim}
+% \pagestyle{fancy}
+% \renewcommand{\chaptermark}[1]{\markboth{Chapter \thechapter. ##1}{}}
+% \renewcommand{\sectionmark}[1]{\markright{\thesection\ ##1}}
+% \end{verbatim}
+% Please note that you have to double the \verb|#| signs, because the
+% definitions are inside a macro.
+%
+% If the previous page style was one of the standard \LaTeX{} page
+% styles, or some page style that is not based on \Package{fancyhdr},
+% then the definitions of \cs{fancyhead} or \cs{fancyfoot} are not
+% affected. So strictly you don't have to include them. But if it was
+% based on \Package{fancyhdr} and had different definitions, you will
+% get the wrong headers and/or footers when you switch back to page
+% style \texttt{fancy}. So it is safer to include them anyway.
+%
+% A better possibility is to define your own page style, and include
+% these definitions in that page style:
+% \begin{verbatim}
+% \fancypagestyle{myfancy}{
+% \renewcommand{\chaptermark}[1]{\markboth{Chapter \thechapter. ##1}{}}
+% \renewcommand{\sectionmark}[1]{\markright{\thesection\ ##1}}
+% \fancyhead{...}
+% }
+% ...
+% \pagestyle{myfancy}
+% \end{verbatim}
+%
+% In general, when you use only one page style \texttt{fancy} in your
+% document, with the occasional \cs{thispagestyle} excursion to page
+% style \texttt{plain} or \texttt{empty}, you can just keep the
+% definitions globally in your document, but as soon as you use more
+% than one page style, and swicth between them, it is highly advisable
+% to define them (including page style \texttt{fancy}) with
+% \cs{fancypagestyle} and put all the relevant definitions inside them.
+%
+% There is another caveat, when switching page styles, if they have
+% different definitions of \cs{chaptermark} in the \texttt{book} or
+% \texttt{report} document class or similar ones. When you put the
+% \cs{pagestyle} command \emph{after} the \cs{chapter} command, then the
+% \cs{chapter} command calls the \cs{chaptermark} of the previous page
+% style, which is probably not what you intended. So you must issue the
+% \cs{pagestyle} command \emph{before} the \cs{chapter} command. But
+% this would probably change the page style of the previous page, which
+% is too early. Therefore you would have to give a \cs{newpage},
+% \cs{clearpage} or \cs{cleardoublepage} command
+% before the \cs{pagestyle} command, so that the last page will be
+% finished with the previous page style. I.e., the proper sequence is:
+% \begin{verbatim}
+% \newpage % (or \clearpage or \cleardoublepage)
+% \pagestyle{newstyle}
+% \chapter{My New Chapter}
+% \end{verbatim}

+% \Author{Author Name}

+% As a chapter starts on a new page, we can be sure that the \cs{Author}

+% text that will appear on the next page. So if our book was not divided
+% into chapters, but into sections, we cannot use the similar system:
+% \begin{verbatim}
+% %%% NOTE: This may not work %%%%
+% \section{Chapter Title}
+% \Author{Author Name}
+% \end{verbatim}
+% because in this case, when this command comes at the end of a page,
+% the ``variable'' \cs{TheAuthor} could be set at that page, but then
+% \TeX{} could decide to move the section title to the next page. And
+% then the author name would appear one page too early. This problem can
+% be solved using marks. In fact this is the whole reason the mark
+% mechanism was developed in \TeX. See section~\ref{sec:xmarks}.
+%
+% The same applies to other changes in the middle of a page, e.g.\ to change the page
+% numbering from roman to arabic (with \cs{pagenumbering}). For the same
+% reason \Cmd{thispagestyle\{mystyle\}} will not always work in the
+% middle of a page.
+%
+% Some of these changes can be accomplished by using the mark
+% mechanism as may be seen in \smartref{sec:change}{sec:scoop} and
+% \smartref{sec:change}{sec:xmarks}.
+%
+% In the remainder of this section we look at two different cases of
+% changing the page style in the middle of a page: changing the style of
+% the current page and changing the style of the next page.
+%
+% \subsection{Changing the page style of the current page}
+%
+% So now we are giving an example how to change the headers and footers,
+% only on the current page. In some cases this can be done by the
+% \CmdIndex{thispagestyle}%
+% \cs{thispagestyle} command. This changes the page style for the
+% ``current'' page only. But then we may be hit by the problem mentioned
+% above. \LaTeX{} may have a different idea about
+% the ``current'' page than you. The use of \cs{thispagestyle} is OK if
+% you can be sure that the text where the command \cs{thispagestyle} is
+% executed is the same page as where the surrounding text appears. So
+% for example directly after a \cs{chapter} command, or after a
+% \cs{newpage}. However, when the command is given near the end of a
+% page, \LaTeX{} may execute the command, and then decide that the page
+% is full and move the text that contains the command to the next page.
+% So now the page style is changed on one page earlier than was intended.
+%
+% A good solution to this problem is to put a label, like
+% \Cmd{label\{otherpagestyle\}} in the text where you want the different
+% page style, and then in the header and/or footer definitions compare
+% the page number with the label page number and choose the proper
+% value. For example, if we want to replace the section title on the
+% special page with ``MYFANCY SECTION'', like in
+% \begin{verbatim}
+% \fancypagestyle{myfancy}{
+% \fancyhead[LE,RO]{MYFANCY SECTION}
+% }
+% \end{verbatim}
+% ^^A\Example
+% we define a new pagestyle that makes the choice:
+% \begin{verbatim}
+% \usepackage{ifthen}
+% . . .
+% \fancypagestyle{switch}{
+% \fancyhead[LE,RO]{%
+% \ifthenelse{\value{page}=\pageref{otherpagestyle}}
+% {MYFANCY SECTION}
+% {\textsl{\rightmark}}}
+% }
+% \end{verbatim}
+% \CmdIndex{ifthenelse}
+% where \verb|\textsl{\rightmark}| is the normal value of the header
+% field from \Cmd{pagestyle\{fancy\}}.
+% Now we choose \Cmd{pagestyle\{switch\}} before our text, or even for
+% the whole document.
+%
+% There can still be some ambiguity on which page gets the different
+% header. For example, if the text says:
+% \begin{quote}
+% This page gets a different header than the surrounding pages.
+% \end{quote}
+% where do you put the \cs{label}? \LaTeX{} could break the page between
+% ``This'' and ``page'', and then would you want the special heading on
+% the page where ``This'' appears, or on the page where ``page''
+% appears. It depends on the positioning of the \cs{label} command.
+% Probably it is safer to make sure the sentence isn't broken. This can
+% be dome by putting the text in a \cs{parbox} or \texttt{minipage} environment.
+% \begin{verbatim}
+% \noindent
+% \begin{minipage}{\textwidth}
+% This page should have a different header than the surrounding pages.
+% \label{otherpagestyle}
+% It is done with the \verb|\pagestyle{switch}| command, that
+% has tests in the header field definitions. This chooses the actual
+% header depending on the page number.
+% \end{minipage}
+% \end{verbatim}
+% The \cs{noindent} is necessary, otherwise the whole \texttt{minipage}
+% will be shifted right by the paragraph indentation.
+%
+% Note that you cannot reset the page style immediately after this code,
+% as this may still influence the current page. If you want to reset it,
+% for example to \Cmd{pagestyle\{fancy\}}, you must be sure that it
+% happens on a following page. But in this case it isn't even necessary,
+% as the special page style acts as the default on all pages except the
+% special page.
+%
+% The special header and footer in page~\pageref{showstruts}, which
+% show the struts are done in a similar way, although the header and
+% footer are a bit more elaborated there.
+% Also there is another complication there, as we also want to make both
+% \cs{headruleskip} and \cs{footrulewidth} dependent on the page number.
+% Unfortunately, this cannot be done with a simple \cs{ifthenelse}
+% \CmdIndex{ifthenelse}
+% command.
+% Both \cs{headruleskip} and \cs{footrulewidth} are eventually
+% used as length parameters, and this requires that they are
+% \emph{expandable}. However, the \cs{ifthenelse} construct is not
+% expandable, so you will get strange error messages if you use
+% something like
+% \begin{verbatim}
+% %%% NOTE: This does not work %%%%
+% \renewcommand{\footrulewidth}{%
+% \ifthenelse{\value{page}=\pageref{otherpagestyle}}{0.4pt}{0pt}%
+% }
+% \end{verbatim}
+% For cases like this \Package{fancyhdr} version~4.0 and later has some
+% new commands \cs{fancyheadinit}, \cs{fancyfootinit} and \cs{fancyhfinit}.
+% \DescribeMacro{\fancyheadinit}
+% With \Cmd{fancyheadinit\{\meta{code}\}} you can define some code that will be executed
+% just before the construction of the header. As it is executed in the
+% header, it can test the correct page number, because the counter
+% \texttt{page} is guaranteed to have the correct value in the headers
+% and footers. Similarly, the code in \Cmd{fancyfootinit\{\meta{code}\}} is executed in
+% \DescribeMacro{\fancyfootinit}
+% the footer. And \Cmd{fancyhfinit\{\meta{code}\}} sets its code for both the header
+% \DescribeMacro{\fancyhfinit}
+% and the footer. Now we can set for example \cs{headruleskip} or
+% \cs{footrulewidth} depending on the page number. So instead of putting
+% the test inside the definition of \cs{headruleskip}, we can put it
+% outside, and then we can use the command \cs{ifthenelse}. So we put
+% the following in \Cmd{pagestyle\{switch\}}:
+% \begin{verbatim}
+% \fancyheadinit{%
+% \ifthenelse{\value{page}=\pageref{otherpagestyle}}
+% {\renewcommand{\headruleskip}{4pt}}
+% {\renewcommand{\headruleskip}{0pt}}
+% }
+% \fancyfootinit{%
+% \ifthenelse{\value{page}=\pageref{otherpagestyle}}
+% {\renewcommand{\footrulewidth}{0.4pt}}
+% {\renewcommand{\footrulewidth}{0pt}}
+% }
+% \end{verbatim}
+% Now here is the definition of the page style used for page~\pageref{showstruts}.
+% \begin{verbatim}
+% \fancypagestyle{showstruts}{%
+% \fancyhead[L]{%
+% \ifthenelse{\value{page}=\pageref{showstruts}}%
+% {\strutheader}%
+% {\rightmark}%
+% }
+% \fancyfoot[L]{%
+% \ifthenelse{\value{page}=\pageref{showstruts}}%
+% {\strutfooter}%
+% {}%
+% }
+% \fancyheadinit{%
+% \ifthenelse{\value{page}=\pageref{showstruts}}%
+% {\renewcommand{\headruleskip}{4pt}}%
+% {\renewcommand{\headruleskip}{0pt}}%
+% }
+% \fancyfootinit{%
+% \ifthenelse{\value{page}=\pageref{showstruts}}%
+% {\renewcommand{\footrulewidth}{0.4pt}}%
+% {\renewcommand{\footrulewidth}{0pt}}%
+% }
+% }
+% \end{verbatim}
+% The label used on that page is \texttt{showstruts}. \cs{strutheader}
+% and \cs{strutfooter} are macros that contain the code to draw these
+% pictures. In this example the values for \cs{headruleskip} and
+% \cs{footrulewidth} in the \emph{else} case are the same as the global
+% values. So we could have left these \emph{else} parts empty. Then they
+% would keep the global values.
+% However, often explicit is better than implicit.
%
+% These initialisation commands cannot be used to make global changes to
+% the page, for example to \cs{headheight}. Neither can you use them to
+% change \cs{fancyhead} or \cs{fancyfoot}, because these have already
+% been set up. But you can use it to set the color and font of the
+% header and/or footer, for example to get large, red text in the
+% headers and footers on this specific page:
+% \begin{verbatim}
+% \fancyhfinit{%
+% \ifthenelse{\value{page}=\pageref{otherpagestyle}}
+% {\color{red}\Large}
+% {}
+% }
+% \end{verbatim}
+%
+% \subsection{Changing the page style of the next page}
+%
+% If you want the change of the page style to take effect
+% at the next page you must make sure that the current page is finished. In
+% most cases this can be done by issuing a
+% \CmdIndex{clearpage}\CmdIndex{newpage}%
+% \cs{newpage} or \cs{clearpage} command before % any changes. However,
+% this will immediately end the current page, possibly leaving you with a
+% half-empty page, which may be undesirable.
+%
+% If this is not what you want, you can use the
+% \TTindex{afterpage.sty}%
+% \Package{afterpage} package with:\\[1ex]
+% \CmdIndex{afterpage}\Cmd{afterpage\{}\Cmd{fancyhead[L]\{new value\}\}} or\\
+% \CmdIndex{pagenumbering}\Cmd{afterpage\{}\Cmd{pagenumbering\{roman\}\}}.
+% \\[1ex]
+% You cannot use \cs{afterpage}
+% to change the \cs{pagestyle} as the commands issued by \cs{afterpage}
+% are local in a group, and the \cs{pagestyle} command makes only local
+% changes. The \cs{pagenumbering} and the \cs{thispagestyle}
+% command make global changes, as well as changes to \LaTeX's counters,
+% such as \cs{setcounter} and \cs{addtocounter}.
+% So these can be used\footnote{In \Package{fancyhdr} version~3 and
+% earlier the commands like \cs{fancyhead} and \cs{fancyfoot} also made
+% global changes. This is no longer the case in version~4.0 and later.}.
+% Here is an example to change the page style of the next page with \cs{afterpage}:
+% ^^A \Example
+% \begin{verbatim}
+% \usepackage{afterpage}
+% \usepackage{fancyhdr}
+% \fancypagestyle{myfancy}{
+% \fancyhead[LE,RO]{\textbf{MYFANCY SECTION}}

+% \fancyfoot[C]{\textbf{--~\thepage~--}}
+% }
+% . . .
+% \afterpage{\thispagestyle{myfancy}}
+% \end{verbatim}
+% Then the page after this code will have the page style \texttt{myfancy}.

+% \label{sec:version-4}
+% Version 4 is a significant rewrite of the package. It also introduces
+% a number of new features.
+% \begin{itemize}
+% \item Version 4.0, March 15, 2020--Jan 04, 2021
+% \begin{itemize}
+% \item Options introduced on the \cs{usepackage} command.
+% \item The check whether the header or footer fits in
+% \cs{headheight} and \cs{footskip}, respectively, no longer
+% adjusts these values for the following pages. This appeared to be too
+% confusing. However, when the package option \texttt{compatV3} is given, the old
+% behaviour is kept. \\
+% The \texttt{nocheck} option now eliminates these checks completely, on
+% your own risk. (See section~\ref{sec:warning} on page~\pageref{page:warning}.)
+% \item Eliminated global definitions. All definitions are now local.
+% The \cs{global} case was originally so that you could do definitions in
+% a group and they would be applied globally. This was a mistake. If
+% you make them locally they should stay local. And it caused
+% problems with switching page styles, because then the global style
+% would be changed, which you generally don't want.\\
+% However, when the package option \texttt{compatV3} is given, the old
+% behaviour is kept. (See section~\ref{sec:options}.)
+% \item The page style \texttt{fancydefault}.
+% \item The \cs{headruleskip} parameter.
+% \item The \cs{fancyheadinit}, \cs{fancyfootinit}, and
+% \cs{fancyhfinit} commands.
+% \item[] \textbf{Note:} The following changes were mostly copied from the
+% \texttt{nccfancyhdr} package by Alexander I. Rozhenko.
+% \item The \cs{fancycenter} command (section~\ref{sec:fancycenter}).
+% \item The \texttt{headings} and \texttt{myheadings} package options
+% (see section~\ref{sec:options}).
+% \item The \cs{fancypagestyle} command has an optional parameter \oarg{base-style}.
