% \section{Introduction}
% \indent This \LaTeX{} package puts the label \texttt{LastPage}
% (at end of the document) into the \xfile{aux} file, allowing the user to refer
% to the last page of a document via |\pageref{LastPage}|.
% This might be particularly useful in places like headers or footers.
%
% \bigskip
%
% This package was invented by \textbf{Jeffrey P. Goldberg},
% and is now maintained by \textsc{H.-Martin Münch}. A~big
% \textquotedblleft Thank you!\textquotedblright{} to
% \textsc{Jeffrey P. Goldberg} for granting this.
%
% \bigskip
%
% If you are more ambitious in respect to your aims with this package,
% you might want to have a look at the \xpackage{pageslts} package
% (see section~\ref{sec:Alternatives}: Alternatives).
%
% \section{Usage}
% \indent Just load the package placing
% \begin{quote}
%   |\usepackage{lastpage}|
% \end{quote}
% \noindent in the preamble of your source file
% (or |\input{lastpage.sty}| if |\usepackage| is unknown).
%
% \indent For example for various draft forms it is desirable to have a
% page reference to the last page, so that e.\,g. page footers can
% contain something like \textquotedblleft page $N$ of $K$\textquotedblright,
% where $N$ is the current page and $K$ is the last page. Once the package
% is loaded, anywhere in the text references can be made to the label
% \texttt{LastPage}. In particular one can use the \xpackage{fancyhdr}
% or \xpackage{nccfancyhdr} package, or redefinitions of the page headings
% and footings to get a reference to the last page.
%
% \noindent In your document the code
% \begin{verbatim}
% \makeatletter
% \renewcommand{\@evenfoot}{%
%  \normalsize\slshape DRAFT \today\hfil \upshape %
%  page \thepage{} of \pageref{LastPage}}
% \renewcommand{\@oddfoot}{\@evenfoot}
% \makeatother
%\end{verbatim}
% \noindent creates footers like\smallbreak
% \textquotedblleft\mbox{\textsl{DRAFT \today}\hspace{1cm}page 7 of 9}\textquotedblright\smallbreak
% \noindent in the compiled document (cf.~the \texttt{lastpage-example} file).\newline
% If the \xpackage{hyperref} package is used, the references are hyperlinked
% to their aims. If these hyperlinks shall be suppressed, |\pageref*{...}|
% instead of |\pageref{...}| can be used.\bigbreak
%
% The \xpackage{lastpage} package does not provide the words
% \textquotedblleft page\textquotedblright{} or \textquotedblleft of\textquotedblright{},
% but e.\,g. the \xclass{handout} class uses \textquotedblleft of\textquotedblright{} in
% the definition of the footer. (In the \texttt{lastpage-example} also
% |\@evenfoot| is redefined, but it is not the \xpackage{lastpage} \emph{package}
% redefining this.) If you want to change \textquotedblleft page\textquotedblright{} or
% \textquotedblleft of\textquotedblright{} (e.\,g. to another language), you therefore
% have got to look in the used class/package(s)/preamble instead of in the
% \xpackage{lastpage} package.\bigbreak
%
% If the total \emph{number} of pages of a document is needed,
% the kernel already gives this by |\makeatletter\@abspage@last\makeatother|,
% |\thetotalpages|, and |\PreviousTotalPages| (needing at least two compiler runs).
% \newpage
%
% \section{Some \textsc{Warnings}\label{sec:warn}}
% \subsection{\texttt{\textbackslash AtEndDocument}\label{ssec:aed}}
% \indent {\bfseries |\AtEndDocument| is not used by the \pkg{lastpagemodern.sty}
% version of the lastpage package, requiring \LaTeX -format 2022-11-01
% or newer. Instead |\AddToHook{enddocument/afterlastpage}| is used
% and the problem does not arise.}
% \bigskip
%
% \pkg{lastpageclassic.sty} uses |\AtEndDocument| and
% \pkg{lastpage209.sty} redefines \linebreak |\enddocument|.
% The last two cases are problematic:\newline
% The output of a \LaTeXe{} run is not independent of the order
% in which the packages are loaded. It is often the case that the same
% formats for which one must put tables and figure at the end,
% are the ones in which endnotes are also required.
% If one wants to use |\AtEndDocument| here as well (as done for
% |\pageref{LastPage}|), then it is easy to get to three separate
% uses of |\AtEndDocument| (assuming one uses this for the endnotes
% as well). Clearly it is not safe for any package writer or user
% to assume that no material will follow what they put into
% |\AtEndDocument|. Therefore a message, which begins with
% \texttt{AED}, is included in every usage of |\AtEndDocument|.
% \xpackage{lastpage} uses |\AtEndDocument{|\ldots|\clearpage|\ldots|}|, thus\newline
%|\usepackage{lastpage}|\ldots|\AtEndDocument{|\textit{something}|}|
% will place \textit{something} after the |\clearpage|. To place it earlier, use\newline
% |\AtEndDocument{|\textit{something}|}|\ldots|\usepackage{lastpage}|.
% If the \textit{something} is not known before |\usepackage{lastpage}|,
% you can use for example
% \begin{verbatim}
% ...
% \def\beforeLastpageClearpage{\relax}
% \AtEndDocument{\beforeLastpageClearpage}
% \usepackage{lastpage}
% \begin{document}
% ...
% \def\beforeLastpageClearpage{\textit{something}}%
% ...
% \end{document}
% \end{verbatim}
% (might need a protected and/or expanded |\def|). When |\clearpage| leads
% to some output, |\clearpage\textit{something}| instead of |\textit{something}|
% might be wanted.
%
% \subsection{Interaction with ancient versions of the \xpackage{endfloat} package\label{sec:endfloat}}
%
% \indent {\bfseries |\AtEndDocument| is not used by the \pkg{lastpagemodern.sty}
% version of the lastpage package, requiring \LaTeX -format 2022-11-01
% or newer. Instead |\AddToHook{enddocument/afterlastpage}| is used
% and the problem does not arise.}
%
% \bigskip
% The \emph{ancient} version~2.0 (and earlier; 2.0~from 1992;
% current version at the time of updating this documentation: 2.7~from 2019)
% of the \xpackage{endfloat} package actually redefined the |\enddocument| command,
% and so interfered drastically with the \LaTeXe{} commands which make use of
% |\AtEndDocument|.
% If you want your \texttt{LastPage} to label the last page of these end floats,
% you need to load \xpackage{lastpage} after loading \xpackage{endfloat}
% (or use \texttt{VeryLastPage} from the \xpackage{pageslts} package instead).
% If, on the other hand, you \emph{want} \texttt{LastPage} to refer
% to the (not so) last page, exclusive of the floats at the end,
% then load in the reverse order. Independent from the order of
% \xpackage{lastpage} and \xpackage{endfloat}, you will still need
% a version of \xpackage{endfloat} later than 2.0 from 1992.
%
% Other \LaTeX2.09{} (!) packages also seem to like to redefine
% |\enddocument|. In addition to the old \xpackage{endfloat},
% \xpackage{harvard} comes to mind. All of these will need to be
% modified swiftly.
%
% \subsection{Page name instead of page number}
% When any page numbering scheme other than \texttt{arabic} is used
% at the page, which |\pageref{LastPage}| refers to, the \textit{name}
% and not the \textit{number} of the page is given. For example,
% \texttt{Alph} page numbering scheme and $10$ pages will give \texttt{J} instead of 10,
% \texttt{Roman} page numbering scheme and $10$ pages will give \texttt{X} instead of 10,
% and so on.\newline
% \indent (The \xpackage{pageslts} package puts |\lastpageref{LastPages}|
% (with \textbf{s} at the end) at your disposal for remediation.)
%
% \subsection{No write access to the \xfile{aux} file}
% Some packages (e.\,g. \xpackage{tikz} and \xpackage{selectp}) sometimes prevent
% the output to the \xfile{aux} file. In that case a warning is issued. This is
% no problem as long as there is another compilation run where the label to the
% last page can be placed via the \xfile{aux} file.
%
% \subsection[Wrong last page number with \textgreater 1 page numbering scheme]{%
%  Wrong last page number with more than one page numbering scheme}
% When more than one page numbering scheme is used,
% \texttt{LastPage} does not give the total \textbf{number} of pages
% (even if \texttt{arabic} is the page numbering scheme of that page).
% For example, for a document with VI+36 pages, it gives
% \textquotedblleft 36\textquotedblright{} as reference to the last page.
% While this is correct, the total number of pages is $42$.\newline
% If the total \emph{number} of pages of a document is needed,
% the kernel already gives this by |\makeatletter\@abspage@last\makeatother|,
% |\thetotalpages|, and |\PreviousTotalPages|.
% The \xpackage{pageslts} package puts |\lastpageref{LastPages}|
% (with \textbf{s} at the end) at your disposal for remediation,
% giving the number of pages and linking to the last page, if linking is provided
% for examaple by the \pkg{hyperref} package.
%
% \subsection{\texttt{\textbackslash addtocounter\{page\}\{\ldots\} and %
%  \texttt{\textbackslash setcounter\{page\}\{\ldots\}}}}
% When the page number was manipulated by |\addtocounter{page}{...}| or
% |\setcounter{page}{...}|, \texttt{LastPage} does not give the total
% \textbf{number} of pages (even if \texttt{arabic} is the page numbering
% scheme of that page).\newline
% The \xpackage{pageslts} package puts |\lastpageref{LastPages}|
% (with \textbf{s} at the end) at your disposal for remediation:
% \texttt{LastPages} ignores page number manipulation. Also |\@abspage@last|,
% |\thetotalpages|, and |\PreviousTotalPages| from the kernel
% are not influenced by page number manipulation.
%
% \subsection{Page number reset by \texttt{\textbackslash pagenumbering\{\ldots\}}}
% At a page numbering change the page number is reset to one.
% Therefore \texttt{LastPage} does not give the total \textbf{number} of pages
% (even if \texttt{arabic} is the page numbering scheme of that page).
% Furthermore, now two pages have the same name.\newline
% The \xpackage{pageslts} package does not only put
% |\lastpageref{LastPages}| (with \textbf{s} at the end) at your disposal
% for remediation: \texttt{LastPages} also ignores page number manipulation.
% It furthermore offers the option |pagecontinue| to continue the
% page numbering, when |\pagenumbering{...}| is used.
%
% \subsection{Last pages of different page numbering schemes}
% |\pageref{LastPage}| refers to the (maybe not so) last page of the last
% page numbering scheme. References to the respective last page of the other
% page numbering schemes are not provided.\newline
% The \xpackage{pageslts} package does this with labels
% \texttt{pagesLTS.<numbering scheme>}, where \texttt{<numbering scheme>} is
% e.\,g. arabic, roman, Roman, alph, or Alph.\linebreak
% For fnsymbol please use |\lastpageref{pagesLTS.fnsymbol}| instead of\newline
% |\pageref{pagesLTS.fnsymbol}|.
%
% \subsection{Current page}
% The command |\thepage| gives the \textbf{name} of the current page
% in the current page numbering scheme, which is different from the
% current total/absolute page number e.\,g. with a second
% page numbering scheme, |\addtocounter{page}{...}|, or |\setcounter{page}{...}|,
% and it will not be an arabic number at all,
% if the current page numbering scheme is not arabic.\newline
% The \xpackage{pageslts} package provides the command
% |\theCurrentPage| and for the current number of pages in the current
% page numbering scheme\newline
% |\theCurrentPageLocal|. The kernel already provides the
% number of pages, which have been shipped out, as |\the\ReadonlyShipoutCounter|.
% The current page is always |ReadonlyShipoutCounter +1|.
%
% \subsection{First page}
% There is no special label at the first page.
% (This is the \textbf{last}\textsf{page} package, after all.)\newline
% The \xpackage{pageslts} package creates a label \texttt{pagesLTS.0}
% at the first page of the document.
%
% \subsection{Page counter overflow\label{ss:overflow}}
% \indent \textquotedblleft The ranges of supported counter values are more or less
% restricted. Only \cs{arabic} can be used with any counter value \TeX{} supports.
% \begin{quote}
% \catcode`\|=12 %
% \begin{tabular}{@{}l|l|l|l@{}}
% Presentation & Supported & Ignored & Error message\\
% command      & domain    & values  & `Counter too large'\\
% \hline
% \cs{arabic}
%   & \ttfamily -MAX..MAX & &\\
% \cs{roman}, \cs{Roman}
%   & \ttfamily 1..MAX & \ttfamily -MAX..0 &\\
% \cs{alph}, \cs{Alph}
%   & \ttfamily 1..26 & 0 & \ttfamily -MAX..-1, 27..MAX\\
% \cs{fnsymbol}

% \hline
% \end{tabular}\\[1ex]
% \texttt{MAX} = \texttt{2147483647}
% \end{quote}
% \textquotedblright{} (\textsc{Heiko Oberdiek}:
% The \xpackage{alphalph} package, 2010/04/18, v2.3, first table, p.~2).
%
% \noindent When \textit{any} page is out of that range, there will be a counter overflow.\newline
% \xpackage{lastpage} probably is not the right package to be asked
% to correct this anyway, but the \xpackage{pageslts} package
% (with appropriate options) can do this.
%
% \subsection{Other packages manipulating \texttt{\textbackslash lastpage@putlabel}}
% The \xpackage{hyperref} package redefined the |\lastpage@putlabel| command,
% and the \xpackage{revtex4} class still redefines the |\lastpage@putlabel| command,
% and the \xpackage{hyperref} package redefined the |\lastpage@putlabel| command,
% if the \xpackage{revtex4} class was used, and the \xpackage{pageslts} package
% \textquotedblleft kills\textquotedblright{} the |\lastpage@putlabel| command,
% because that package uses more advanced labels.\newline
% In my humble opinion it would be preferably if one package (the original one,
% i.\,e. \xpackage{lastpage}) would do the job right, all others packages would
% check for the version of that package, and if an old version is found,
% an error (or at least a warning) message about the use of an outdated
% package is given, and \textit{then} as
% \textquotedblleft last aid\textquotedblright{} the command of the outdated
% package is redefined.\newline
% Therefore here none of the definitions or commands of the other packages
% is altered, but |\lastpage@putlabel| was replaced by |\lastpage@putl@bel|.
% Because |\lastpage@putlabel| is no longer called, now there should not be any
% double definitions of the \texttt{lastpage} label.
% \newpage
%
% \section{Alternatives\label{sec:Alternatives}}
% There are similar packages, which do (or do not) similar things (or even more).
% As I neither know what exactly you want to accomplish when using this package
% (e.\,g.~page number vs. page name, hyperlinks or not), nor what resources
% you have (e.\,g.~\TeX, \LaTeX2e, $\varepsilon$-\TeX{}, \LaTeX-format as recent
% as 2022-11-01 or newer), here is a list of some possible alternatives:
%
% \DescribeMacro{pageslts}\vspace*{-\baselineskip}
% \begin{description}
% \item[-]
%  \textbf{Note: The current version 2015/12/21 v1.2f of the \pkg{pageslts} package
%  has not yet been updated to the new hook mechanism. In special cases (for example }%
%  |\pagenumbering{fnsymbol}|\textbf{) the current version of that package combined
%  with a current \LaTeX-format fails. Together with about 80~other packages
%  (small to large, public as well as private, some probably obsolete) it is
%  in the update queue.}\newline
%  The \xpackage{pageslts} package first started as a revision of this
%  \xpackage{lastpage} package, but it became obvious that a replacement was
%  needed to accomplish what the \xpackage{pageslts} package does. For backward
%  compatibility, a label named |LastPage| is provided.
%  Thus |\usepackage{lastpage}| can be replaced by\newline
%  |\usepackage[pagecontinue=false,alphMult=0,AlphMulti=0,|\newline
%  | fnsymbolmult=false,romanMult=false,RomanMulti=false]{pageslts}|,\newline
%  if the behaviour of the \xpackage{lastpage} package should be simulated.
%  The default options are\newline
%  |\usepackage[pagecontinue=true,alphMult=ab,AlphMulti=AB,|\newline
%  |fnsymbolmult=true,romanMult=true,RomanMulti=true]{pageslts}|.\newline
%  Benefits of \xpackage{pageslts} package (with appropriate options) are:
%  \begin{description}
%  \item[+] Labels \texttt{LastPage} (|\AtEndDocument|) and\newline
%   \texttt{VeryLastPage} (|\AfterLastShipout|),\newline
%   allowing the user to refer to the (very) last page of a document.
%  \item[+] For example, when more than one page numbering scheme is used,
%    the label \texttt{LastPage}\textbf{s} gives the total \textit{number} of pages.
%  \item[+] At the last page of each page numbering scheme a label\newline
%   \texttt{pagesLTS.<numbering scheme>} is placed, where
%   \texttt{<numbering scheme>} is e.\,g. arabic, roman, Roman, alph, or Alph.
%   For fnsymbol please use |\lastpageref{pagesLTS.fnsymbol}| instead of\newline
%   |\pageref{pagesLTS.fnsymbol}|.
%  \item[+] When the same numbering scheme is used twice, the page numbers
%   are either reset to one or continued automatically, depending on the option
%   given when the package is called.
%  \item[+] The command |\theCurrentPage| prints the current total/absolute
%   page number -- in contrast to |\thepage|, which gives only the page
%   \textit{name} in the current page numbering scheme.
%   |\theCurrentPageLocal| gives the current number of pages in the current
%   page numbering scheme. |\thepage| and |\theCurrentPageLocal| are different
%   e.\,g. when |\addtocounter{page}{...}| or |\setcounter{page}{...}| were used.
%  \item[+] At the first page of the document a label \texttt{pagesLTS.0} is created.
%  \item[+] The \xpackage{alphalph} package is supported, i.\,e.
%   page numbers alph or Alph $>26$ and fnsymbol $>9$ can be used
%   (with according options set). Even zero and negative page numbers can be used
%   with \texttt{arabic}, \texttt{alph}, \texttt{Alph}, \texttt{roman}, \texttt{Roman},
%   and \texttt{fnsymbol} page numbering (with \xpackage{alphalph} package and
%   according options).
%  \item[+] It is checked whether a (very) old \xpackage{endfloat} package
%   is in use. If it is, a warning or even an error message is given,
%   depending on \xpackage{endfloat} version.
%  \item[+] A rerun warning is given, when labels have changed.
%  \end{description}
%  Further labels are provided for special cases.
% \end{description}
%
% \DescribeMacro{totpages}\vspace{-\baselineskip}
% \begin{description}
% \item[-] The \xpackage{totpages} package provides a \texttt{totpages} label similar to
%  \texttt{LastPages}\newline
%  |\AtEndDocument| (instead of |\AfterLastShipout|, as done by \xpackage{pageslts}).
%  The \xpackage{totpages} package additionally computes the number of paper sheets
%  needed to (double) print the document (with one, two, three,\ldots{} pages on
%  one sheet of paper) (which can be achieved also with the \xpackage{papermas} package,
%  an extension of the \xpackage{pageslts} package, which further allows to compute
%  the mass of that printed version of the document, useful e.\,g. when sending it
%  by mail to determine the postage).
% \end{description}
%
% \DescribeMacro{nofm.sty}\vspace{-\baselineskip}
% \begin{description}
% \item[-] \textquotedblleft There is a package \xpackage{nofm.sty} available,
%  but some versions of it are defective, and most don't work with \xpackage{fancyhdr}
%  because they take over the complete page layout.\textquotedblright (\textsc{Piet van %
%  Oostrum}: Page layout in \LaTeX{}, March~2, 2004, section~16; fancyhdr.pdf)\newline
%  \xpackage{nofm} as of 1991/02/25 (without version number), available at\newline

%  does not work with e.\,g. \xpackage{hyperref}, redefines |\enddocument|

%  If you know the (CTAN) location of a \textbf{working}~(!) version,
%  please send an e-mail to the \xpackage{lastpage} maintainer, thanks!
% \end{description}
%
% \DescribeMacro{count1to}\vspace{-\baselineskip}
% \begin{description}
% \item[-] You may want to have a look at the \xpackage{count1to} package.
% \end{description}
%
% \DescribeMacro{totalcount}\vspace{-\baselineskip}
% \begin{description}
% \item[-] The \xpackage{totalcount} package provides |\totalpages|.
%  If there are only arabic page numbers consecutively running from 1 to the last page,
%  this works. But for example
%
% \begin{quote}
%\begin{verbatim}
%\documentclass{article}
%\usepackage[page]{totalcount}
%\pagenumbering{Roman}
%\begin{document}
%\addtocounter{page}{49}
%Page \thepage{} of \totalpages
%\end{document}
%\end{verbatim}
% \end{quote}
%
%  prints \textquotedblleft Page L of 50\textquotedblright,
%  where the number of pages is one (and no hyperlink is provided to the
%  last page even if \xpackage{hyperref} is used).
% \end{description}
%
% \DescribeMacro{zref}\vspace{-\baselineskip}
% \begin{description}
% \item[-] The \xpackage{zref} package of \textsc{Heiko Oberdiek} requires
%  $\varepsilon$-\TeX{}. \xpackage{lastpageclassic} does not require $\varepsilon$-\TeX{},
%  but if you already have $\varepsilon$-\TeX{} (and use \xpackage{lastpagemodern}),
%  you may also have a look at the extensive \xpackage{zref} package,
%  whether it suits your needs better (or additionally or whatsoever).
% \end{description}
%
% \DescribeMacro{memoir}\vspace{-\baselineskip}
% \begin{description}
% \item[-] The \xpackage{memoir} \emph{class} provides |\thelastpage| (page number printed
%  on last page) and |\thelastsheet| (number of pages).
% \end{description}
%
% \DescribeMacro{LaTeX-kernel}\vspace{-\baselineskip}
% \begin{description}
% \item[-] The number of pages is nowadays available via |\@abspage@last|,
%  |\thetotalpages|, and |\PreviousTotalPages| from the kernel,
%  but when more than one page numbering scheme is used
%  (for example pages I~to X and then 1~to 10, thus number of pages
%  \hbox{\textquotedblleft 20\textquotedblright ,} but name of the last page
%  \hbox{\textquotedblleft 10\textquotedblright ),}
%  or when or the fnsymbol page numbering scheme is used, or another package
%  has output after this package, or the page numbers exceed a certain range,
%  there might be issues. (Is the total number of pages wanted? Or is the name
%  of the last page sought?)

\begin{quote}

\documentclass{article}
\usepackage{hyperref}
\usepackage{lastpage}
\begin{document}
\ifnum\thepage=\pageref{LastPage} foo \else bar \fi

producing the error
\textquotedblleft missing number, treated as zero\textquotedblright.
\end{quote}

\noindent \verb|\pageref| inserts a hyperlink, \verb|\pageref{LastPage}|
is not expandable and the code breaks.\newline
The code does not generally work even without hyperref.

\begin{quote}
\begin{verbatim}
\documentclass{article}
\usepackage{hyperref}
\usepackage{lastpage}
\pagenumbering{Roman}
\begin{document}

\edef\here{\thepage}
\makeatletter

\end{document}
\end{verbatim}
\end{quote}

\noindent does work, because \verb|\lastpage@lastpage| contains the name
of the page, \mbox{example:}
\begin{verbatim}
Page \thepage{} is (not) page \makeatletter\lastpage@lastpage\makeatother.
\end{verbatim}
prints:\newline
Page \thepage{} is (not) page \makeatletter\lastpage@lastpage\makeatother.
\newline
This can be broken for example by \verb|\pagenumbering{fnsymbol}|
(because then \verb|\edef\here{\thepage}| does not work).
\newpage

With modern \LaTeX{} it is possible to say:

% leads to failed detection of the \xpackage{hyperref} package, because
% |\AtBeginDocument| \textit{first} the check for \xpackage{hyperref} is performed,

% |\@ifpackageloaded| cannot be used later, so here we do not check for the
% \xpackage{hyperref} package again, but for its |\Hy@Warning| command.
% In version~1.2c of the \xpackage{lastpage} package, it was checked for
% the |\hyperref| command, but as it turned out, \xpackage{tcilatex} \textit{is}
% defining that. If some other package or user is defining |\Hy@Warning|,
% \xpackage{lastpage} will falsely assume, that \xpackage{hyperref} has been loaded,
% but in my humble opinion, defining |\Hy@Warning| does not make sense and
% is bad style (except definition by the \xpackage{hyperref} package itself,
% of course).

    }{\gdef\lastpage@hyper{1}% hyperref loaded
     }%
%    \end{macrocode}
%
% If the \xpackage{pageslts} package is used, this \xpackage{lastpage} package is
% not needed at all. The \xpackage{LastPage} label would even be defined twice.
% Thus, if \xpackage{pageslts} is used, here nothing is done:
%
%    \begin{macrocode}
  \ifx\lastpage@LTS\lastpage@one%
  \else%
%    \end{macrocode}
%
% Otherwise the label is set:\newline
% We have got to distinguish whether \xpackage{hyperref} has been loaded or not:
%
%    \begin{macrocode}
    \ifx\lastpage@hyper\lastpage@one%
      \lastpage@putlabelhyper%
    \else%
%    \end{macrocode}
%
% and also need to treat documents with \xpackage{nameref} differently:
%
%    \begin{macrocode}
      \ifx\lastpage@nameref\lastpage@one%
        \lastpage@putlabelNR%
      \else%
%    \end{macrocode}
%
% When those packages have not been loaded, we just write the
% simple label into the \xfile{aux} file (and store the value of the page):
%
%    \begin{macrocode}
        \begingroup%
          \addtocounter{page}{-1}%

%
% \subsection{Refresh file name databases}
% If your \TeX~distribution (\TeX\,Live, \mikTeX, \dots) relies on
% file name databases, you must refresh these. For example, \TeX\,Live\ users
% run \verb|texhash| or \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
% \paragraph{Unpacking with \LaTeX.}
% The \xfile{.dtx} chooses its action depending on the format:
% \begin{description}
% \item[\plainTeX:] Run \docstrip{} and extract the files.
% \item[\LaTeX:] Generate the documentation.
% \end{description}
% If you insist on using \LaTeX{} for \docstrip{} (really,
% \docstrip{} does not need \LaTeX ), then inform the autodetect routine
% about your intention:
% \begin{quote}
%   \verb|latex \let\install=y\input{lastpage.dtx}|
% \end{quote}
% Do not forget to quote the argument according to the demands
% of your shell.
%
% \paragraph{Generating the documentation.\label{GenDoc}}
% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
% the documentation. The process can be configured by a
% configuration file \xfile{ltxdoc.cfg}. For instance, put the following
% line into this file, if you want to have A4 as paper format:
% \begin{quote}
%   \verb|\PassOptionsToClass{a4paper}{article}|
% \end{quote}
%
% \noindent An example follows how to generate the
% documentation with \pdfLaTeX :
%
% \begin{quote}
%\begin{verbatim}
%pdflatex lastpage.dtx
%makeindex -s gind.ist lastpage.idx
%pdflatex lastpage.dtx
%makeindex -s gind.ist lastpage.idx
%pdflatex lastpage.dtx
%\end{verbatim}
% \end{quote}
%
% \subsection{Compiling the example}
% The example file, \textsf{lastpage-example.tex}, can be compiled via\newline
% \indent |latex lastpage-example.tex|\newline
% or (recommended)\newline
% \indent |pdflatex lastpage-example.tex|\newline
% and will need at least two compiler runs to get all references right.

%     \item Replacement of |\filedate|, |-version|, |-name|,\ldots{} because
%             of \LaTeX{}~bug 2705:\newline
%             Synopsis: Possible problem with |\fileversion| and |\filedate|\newline
%             \url{https://www.latex-project.org/cgi-bin/ltxbugs2html?category=LaTeX&responsible=anyone&state=anything&keyword=lastpage&pr=latex/2705}
%     \item Example |lastpage-example.tex|.
%     \item Alternatives listing (section \ref{sec:Alternatives}).
%     \item Listing of \TeX{} sources (subsection \ref{ss:Downloads}).
%     \item Really a lot of details.
%     \item Complete rewriting of the documentation.
%     \item Everything in \texttt{DTX} framework.
%     \item Included a |\CheckSum|. [Removed in v2.0a.]

%   \end{Version}
%   \begin{Version}{2010/08/12 v1.2b}
%     \item Bug fix: |\@PackageInfoNoLine| is only available,
%             if the \xpackage{hyperref} package is loaded.
%             (Bug reported by \textsc{Ulrike Fischer}, thanks!)
%     \item Bug fix: |\ifHy@pageanchor| etc. do not work without
%             \xpackage{hyperref}, and |\else| related to |\ifHy@pageanchor| was
%             wrongly associated with a preceding |\if|, and everything went wrong.
%             Now everything should work again also without \xpackage{hyperref}.
%     \item Renamed |\lastpage@putlabel| to |\lastpage@putl@bel| to get rid of
%             the conflicts with other classes and packages and resulting
%             multiple definitions of the \texttt{lastpage} label.
%   \end{Version}
%   \begin{Version}{2010/08/23 v1.2c}
%     \item Bug fix: Additionally to checking for the \xpackage{hyperref} package
%             |\AtBeginDocument|, when placing the \texttt{lastpage} label it is also
%             checked for the |\hyperref| command, in case \xpackage{hyperref} was not
%             loaded at |\begin{document}| yet. (Bug reported by \textsc{Sebastian Bank},
%             thanks!)\newline
%             [\pkg{lastpagemodern.sty} just uses |\IfPackageLoadedTF{hyperref}|.]
%     \item Changed the |\unit| definition (got rid of an old |\rm|). [Removed in v2.0a.]
%     \item Changed |\lastpage@puthyperlabel| to |\lastpage@putlabelhyper| analogous to
%             |\pagesLTS@putlabelhyper| of the \xpackage{pageslts} package.
%     \item Updated version number and date of \xpackage{pagesLTS} package (especially
%             for the check for outdated versions). [Removed in v2.0a.]
%     \item Removed wrong \%\ from the driver file.
%   \end{Version}
%   \begin{Version}{2010/08/25 v1.2d}
%     \item Bug fix: also \xpackage{tcilatex} defines the |\hyperref| command,
%             therefore for \xpackage{hyperref} package detection this had to be
%             changed to |\Hy@Warning|.\newline
%             [\pkg{lastpagemodern.sty} just uses |\IfPackageLoadedTF{hyperref}|.]
%   \end{Version}
%   \begin{Version}{2010/09/12 v1.2e}
%     \item \textsc{James Hedges} pointed out, that there was no instruction in the
%             documentation about suppressing hyperlinks: added (also to the example).
%     \item Diverse small changes.
%   \end{Version}
%   \begin{Version}{2010/09/24 v1.2f}

%     \item New version of \xpackage{pagesLTS} package, 2010/09/22, v1.1k.
%     \item Moved the package from \texttt{.../latex/muench/lastpage/...} to\newline
%             \texttt{.../latex/lastpage/...}.

%     \item Updated to version 2010/12/16 v6.81z of the \xpackage{hyperref} package.
%     \item Minor details.
%   \end{Version}
%   \begin{Version}{2011/07/03 v1.2h}
%     \item The \xpackage{holtxdoc} package was fixed, therefore the warning
%             in \xfile{drv} could be removed.~-- Adapted the style of this documentation
%             to new \textsc{Oberdiek} \xfile{dtx} style.

%             2011/08/08, v1.2a.
%     \item Some details.
%   \end{Version}
%   \begin{Version}{2011/08/31 v1.2j}
%     \item Updated to \TeX{} Live 2011 (for compiling the documentation and example).
%     \item New version of \xpackage{papermas} package, 2011/08/22, v1.0h.
%     \item Adapted for the use together with packages, which sometimes prevent writing

%   \end{Version}
%   \begin{Version}{2011/09/01 v1.2k}
%     \item Fixed |\thepage{}| to \mbox{|\thepage{}|\textvisiblespace,}
%             where there should be a space.
%     \item New version of the \xpackage{hyperref} package, 2011/08/19, v6.82h,
%             but still problem with links to pages with
%             page-\textquotedblleft number\textquotedblright{} in \texttt{fnsymbol}
%             pagenumbering scheme. [Fixed since v6.83m as of 2012/11/06.]
%     \item Documentation update about \textquotedblleft No write access to the
%             \xfile{aux} file\textquotedblright .
%   \end{Version}
%   \begin{Version}{2013/01/28 v1.2l}
%     \item Updated to \TeX{} Live 2012 (for compiling the documentation and example).
%     \item New versions of the packages
%             \xpackage{endfloat}, \xpackage{holtxdoc}, \xpackage{hypdoc},
%             \xpackage{hyperref}, \xpackage{pageslts}, \xpackage{regstats},
%             \xpackage{ulem}, and \xpackage{zref} have become available.
%     \item The \xpackage{nameref} package redefines |\label| to have five arguments
%           instead of two, therefore |\newlabel{LastPage}{{}{\thepage}{}{}{}}| instead of
%           |\newlabel{LastPage}{{}{\thepage}}| must be used.
%           (Bug reported at \url{https://tex.stackexchange.com/q/95541},
%           thanks to \textsc{Micha\l{} Herman}!) Fixed.\newline
%           [Since \LaTeX{} release 2023-06-01 five arguments are standard.]

%   \end{Version}
%   \begin{Version}{2023-03-07 v2.0a}
%     \item Removed use of \pkg{ulem}.
%     \item Removed |\unit|.
%     \item \pkg{lastpage} should now determine automatically, whether to load
%             its \TeX~2.09 version, classic \LaTeX2e-version, or modern version
%             with \eTeX, hook{-}man\-age\-ment etc.

%   \end{Version}
%   \begin{Version}{2023-10-06 v2.0d}
%     \item For plain arabic page numbers only, \pkg{lastpage} again writes the page number
%             in a plain format in the label in the \xfile{aux} file, so that it can be extracted
