+%
+% This package implements a system for eXternal References.
+%
+% It is an extension of the \pkg{xr} package. It was developed to support the
+% extended label syntax of the \pkg{hyperref} package and to enable active links
+% to the external documents.
+%
+% In the \LaTeX{} release 2023-06-01 the label syntax of \pkg{hyperref}
+% and the \LaTeX{} kernel have been synchronized and there is no longer
+% a need for two packages. \pkg{xr-hyper} already works with all documents --
+% it is not required to load\pkg{hyperref} -- and its code will move in the
+% next \LaTeX{} release into the \pkg{xr} package. Then \pkg{xr-hyper} can be
+% deprecated.
+%
+% \section{Usage}
+%
+% \begin{syntax}
+% \cs{externaldocument}\oarg{prefix}\texttt[nocite\texttt]\marg{document}\oarg{url}
+% \end{syntax}
+%
+% If one document needs to refer to sections of another, say |aaa.tex|,
+% then this package may be loaded in the main file, and the command
+% \begin{verbatim}
+% |\externaldocument{aaa}|
+% \end{verbatim}
+% given in the preamble.
+%
+% Then you may use |\ref| and |\pageref| (or |\nameref| if the
+% package \pkg{nameref} has been loaded to refer to anything which has
+% been given a |\label| in either |aaa.tex| or the main document.
+% You may declare any number of such external documents.
+%
+% If any of the external documents, or the main document, use the same
+% |\label| then an error will occur as the label will be multiply
+% defined. To overcome this problem |\externaldocument| has an optional
+% argument \meta{prefix}.
+% If you declare |\externaldocument[A-]{aaa}|, then all
+% references from |aaa| are prefixed by |A-|. So for instance, if a
+% section of |aaa| had |\label{intro}|, then this could be referenced
+% with |\ref{A-intro}|. The prefix need not be |A-|, it can be any
+% string chosen to ensure that all the labels imported from external
+% files are unique. Note however that the prefix is expanded and
+% so should not contain commands that are not safe in this context.
+%
+% As first suggested in Enrico Gregorio's |xcite| package, the current version
+% also allows |\cite| to reference |\bibitem| in the external document.
+% For compatibility with |xcite|, |\externalcitedocument| is made available
+% as an alias for |\externaldocument|
+%
+% Many packages have variant citation commands (natbib,
+% biblatex,....) and the external document may or may not have used
+% hyperref. Because of these differences the citation linking may not
+% always work, it can be disabled by specifying \texttt{[nocite]} after the
+% \meta{prefix}:
+% \begin{verbatim}
+% \externaldocument[][nocite]{aaa}
+% \end{verbatim}
+%
+% The `document' referred to by the main argument \meta{document} is the file
+% \file{document.aux} which must be somewhere on TeX's input path.
+% Some packages (eg hyperref) really need to know the location of the
+% final document rather than the aux file. By default this is assumed
+% to be \file{document.pdf}. A package may redefine the command \cs{XR at ext} to
+% change this default extension. However sometimes the final
+% document may be in a position unrelated to the aux file, or the
+% browser may not be able to find files at an arbitrary point in
+% TeX's input path, so the final optional argument \meta{url} allows a full
+% URL to the final document to be specified.
+% \begin{verbatim}
+% \externaldocument{aaa}[http://here.xxx.edu/this/path/to/aaa.pdf]
+% \end{verbatim}
+%
+% The package stores the url of the external document in the label data. If can
+% e.g. be retrieved with the \pkg{refcount} package
+%
+% \begin{verbatim}
+% \usepackage{refcount,xr-hyper}
+% \externaldocument{aaa}
+% ...
+% \getrefbykeydefault{intro}{url}{??} %prints aaa.pdf or ??
+% \end{verbatim}
+%
+% \pkg{xr-hyper} supports also the properties introduced in \LaTeX{} 2023-11-01.
+% Here the url of the external document is stored in the \texttt{xr-url} property.
+%
+% \begin{verbatim}
+% \usepackage{xr-hyper}
+% \externaldocument{aaa} %aaa contains \RecordProperties{intro}{page}
+% ...
+% \RefProperty{intro}{page} %gives page number
+% \RefProperty{intro}{xr-url} %gives aaa.pdf
+% \end{verbatim}
+%

+%
+% \section{The macros}
+%
+% \begin{macrocode}
+%<*package>
+% \end{macrocode}
+%
+% Check for the optional argument.
+% \begin{macrocode}
+\def\externaldocument{\@testopt\XR at cite{}}
+\let\externalcitedocument\externaldocument
+\def\XR at cite[#1]{\@testopt{\XR@[#1]}{}}
+\def\XR@[#1][#2]#3{\@testopt{\XR@@{#1}{#2}{#3}}{#3.\XR at ext}}
+% \end{macrocode}
+%
+% \subsection{helper definitions}
+% To test the second optional argument
+% \begin{macrocode}
+\def\XR@@nocite{nocite}
+% \end{macrocode}
+% Needed in the processing
+% \begin{macrocode}
+\long\def\@gobblefour #1#2#3#4{}
+\long\def\@firstoffour #1#2#3#4{#1}
+\long\def\@secondoffour#1#2#3#4{#2}
+\long\def\@thirdoffour #1#2#3#4{#3}
+\long\def\@fourthoffour #1#2#3#4{#4}
+% \end{macrocode}
+% The url is added as fifth argument. The command used here is
+% \cs{XR at addURL}. The command is more complicated as needed
+% as it tries to handle also older documents with
+% \cs{newlabel}'s with two arguments.
+% \begin{macrocode}
+\def\XR at addURL#1{\XR@@dURL#1{}{}{}{}\\}
+\def\XR@@dURL#1#2#3#4#5\\{%

+% \end{macrocode}
+%
+% \subsection{Variables}
+%
+% Default file extension:
+% \begin{macrocode}
+\providecommand\XR at ext{pdf}
+% \end{macrocode}
+%
+% \subsection{Processing}
+% Save the optional prefix. Start processing the first |aux| file.
+% Version beta2 also added another improvement unrelated
+% to the hyperref support. Olivier Michel pointed out that
+% if the aux file was not on texinputs you could not always go
+% \cs{externaldocument}{/some/path/to/file}
+% specifically that worked if file.aux was a `simple' document with
+% one aux file, but if \cs{include} had been used, the `sub' aux files
+% would not be found by xr in the remote directory.
+% This version calls \cs{filename at parse} to get the directory name of the
+% remote directory, which is then explicitly prepended to the names of
+% any included aux files.
+% \begin{macrocode}
+\def\XR@@#1#2#3[#4]{{%
+ \makeatletter
+ \def\XR at prefix{#1}%
+ \def\XR at nocite{#2}%
+ \ifx\XR at nocite\XR@@nocite

+ \let\XR at bibcite\bibcite
+ \fi
+ \def\XR at URL{#4}%
+ \filename at parse{#3}%
+ \XR at next#3.aux\relax\\}}
+% \end{macrocode}
+%
+% Process the next |aux| file in the list and remove it from the head of
+% the list of files to process.
+% \begin{macrocode}
+\def\XR at next#1\relax#2\\{%
+ \edef\XR at list{#2}%
+ \XR at loop{#1}}
+% \end{macrocode}
+%
+% Check whether the list of |aux| files is empty.
+% \begin{macrocode}
+\def\XR at aux{%
+ \ifx\XR at list\@empty\else\expandafter\XR at explist\fi}
+% \end{macrocode}
+%
+% Expand the list of aux files, and call |\XR at next| to process the first
+% one.
+% \begin{macrocode}
+\def\XR at explist{\expandafter\XR at next\XR at list\\}
+% \end{macrocode}
+%
+% If the |aux| file exists, loop through line by line, looking for
+% |\newlabel| and |\@input|. Otherwise process the next file in the
+% list.
+% \changes{v7.01h}{2024-01-20}{Add braces around the filename to
+% support filenames with spaces (gh/223) similar to xr}
+% \begin{macrocode}

+ \PackageInfo{xr}{IMPORTING LABELS FROM #1}%
+ \expandafter\XR at read\fi}
+% \end{macrocode}
+%
+% Read the next line of the aux file.
+% \begin{macrocode}
+\def\XR at read{%
+ \read\@inputcheck to\XR at line
+% \end{macrocode}
+% The |...| make sure that |\XR at test| always has sufficient arguments.
+% \begin{macrocode}
+ \expandafter\XR at test\XR at line...\XR@}
+% \end{macrocode}
+%
+% Look at the first token of the line.
+% If it is |\newlabel|, define \cs{r@}\meta{label}, ensure that it has
+% five label data argument and add the url as the last one.
+% If it is |\@input|, add the
+% filename to the list of files to process.
+% If it is |\bibcite|, call a |\bibcite|.
+% If it is |\new at label@record| add the url and then call it.
+% Otherwise ignore.
+% Go around the loop if not at end of file. Finally process the next
