% \section{Introduction}
% This package allows to typeset version control (VC) information provided by 
% Subversion\footnote{Subversion homepage: \url{http://subversion.tigris.org/}} 
% keywords (\eg |$||Id: ... $|) in \LaTeX\ documents which can contain of 
% multiple |.tex| files included using |\include| or |\input|.
% Subversion is a modern version control system designed to replace its 
% predecessor CVS and uses integers as revision numbers.
%
% This package reads the keywords of all files and provides the VC information 
% of of the most recent changed file of the document to the user through a set 
% of macros. This information is written to an auxiliary |.svn| file during the 
% first \LaTeX\ run and read back at the next which introduces the same delay 
% known from the table of contents. The standard \LaTeX{} switch |\nofiles| can 
% be used to suppress the file generation.
%
% In addition to this basic functionality several more features are provided:
% \begin{itemize}
%   \item Macros to typeset the VC information of the current source file.
%   \item Access of all parts of the VC date.
%   \item Formatting of author names or revision numbers.
%   \item Definition of groups and subgroups.
%   \item Including of the VC information of external files.
%   \item Table of Revisions.
% \end{itemize}
% \newpage
%
% \subsection{Scope of Keywords}
% This package provides the Subversion keyword data in several different scopes:
% document-global, file-local and, new with v2.0, by group.
%
% \subsubsection*{Document Global}
% The document global macros, like \cs{svnrev}, return the latest version 
% control information (keyword data) for the whole multi-file document, \ie the 
% information of the latest changed file of the document. To collect, sort and 
% provide this information is the main functionality of this package.
%
% \subsubsection*{Local to Current File}
% There are also file-local macros, \eg \cs{svnfilerev}, which return the 
% version control information of the current file, \ie the file they are used 
% in. It is assumed here that every file using this macros calls first either a 
% \cs{svnid} or \cs{svnidlong} macro or both.  See section~\ref{sec:usage:id} 
% for more details about the id macros.  Please note that the file-local macros 
% technically actually return the \emph{last registered} information from the 
% last \cs{svnid} or \cs{svnidlong}. As long the \op{filehooks} option (new in 
% v2.0) is not enabled (explicit or implicit) this keyword macros will leak from 
% one file over to the next.  This will cause wrong results if they are used in 
% a file before or without any id macros. With this option the macros will be 
% reset at the beginning of every source file of the document.
%
% \subsubsection*{Groups}
% Version 2.0 introduces the concept of groups. Several files of a multi-file 
% \LaTeX\ document can be grouped together and the latest version control 
% information of all files of a group is provided by macros. This works in the 
% same way as the global macros mentioned above but only with the files in the 
% group. It can also be seen from the other side: the macros are local like the 
% file-local macros mentioned above but for all files of the group, not only the 
% current one.
%
% These groups could also be called \textit{file groups}, \textit{keyword 
% groups} or, like in programming languages, \textit{namespaces}. In this manual 
% they will be reference as simple \textit{groups} most the time. In places 
% where they could be confused with \TeX\ groups (|{ }|, |\begingroup| 
% |\endgroup|), \eg ``in the current group'' or ``group local'', they will be 
% called \textit{keyword groups}.
%
% There is no limitation (besides internal \LaTeX\ resource limits) for the 
% number of different groups. The files of one group do not have to be included 
% in a row but can be included everywhere in the document. The version control 
% information of the current group can be typeset with macros like \cs{svncgrev} 
% (|cg| for \emph{current group}).  Also, a general but less robust macro 
% \cs{svng}\marg{group name}\marg{key} is provided to access others groups by 
% name everywhere in the document. To avoid some macro robustness problems the 
% current group can be changed locally for the output macros using 
% \cs{svnsetcg}\marg{group name}.
%
% See section~\ref{sec:group} for further details and usage instructions on 
% group macros.
%
% \section{Usage}
% The version control information are provided by Subversion keywords which
% first need to be read in by dedicated macros and can then be typeset using
% different macros.
%
% \subsection{Package Options}
% Since v2.0 this package provides options to enable only a needed features, \eg 
% to avoid problems with other packages or save \TeX\ memory. For backwards 
% compatibility to pre-2.0 package versions all old features are enabled by 
% default and all new features are disabled to save a little of \TeX\ memory.
%
% All options except the first two are boolean key=value options (so far) and
% await either `|true|' or `|false|' as value. A missing value means `|true|'.
% So \eg |[groups=true,verbatim=false,external]|, enables the \op{external} and
% \op{groups} options but disables the \op{verbatim} option.
%
% The available options are:\par
%
% \DescribeOption{old}
% Only pre-v2.0 features are active. This enables \op{verbatim} and disables all 
% other options below. This is the default for reasons mentioned above.
%
% \DescribeOption{all}
% Activates all features of the package except of the experimental ones.
%
% \DescribeOption{verbatim}
% Controls the verbatim mode of the keyword parser macros. Normally verbatim 
% mode is very much wanted to support strange characters in URLs and file names, 
% but this options gives the user a possibility to disable verbatim, \eg for 
% trouble shooting.  Please note that verbatim mode is needed in order to make 
% \svnmulti work with some packages, like \pkg{babel} with the |french| option.
%
% \DescribeOption{external}
% Controls the support for keywords from external files described in 
% section~\ref{sec:external}. This needs either the external script 
% \scr{svn-multi.pl} or the \op{autokw} option.
%
% If the \op{groups} option is enabled the macro 
% \csi{svnexternalgroup}\marg{group name} can be used to declare a own group 
% which is used for all the external files.  Otherwise they are placed in the 
% currently active group.  This macro can be used several times during the 
% document where an empty argument means \emph{no group} and a `|*|' means 
% \emph{current group}.
%
% \DescribeOption{groups}
% Controls the keyword groups feature described in section~\ref{sec:group}.
%
% \DescribeOption{subgroups}
% Controls the automatic declaration of all input files as subgroups so that 
% there keyword information can be typeset inside other files. The group name is 
% the file path without the file extension (`|subdir/filebase|').
% It is possible to disable and re-enable this using \cs{svnsubgroupsfalse} and 
% \cs{svnsubgroupstrue} during the document preamble or body to exclude certain 
% files.  See section~\ref{sec:subgroups} for additional information.
%
% \DescribeOption{graphics}
% This option allows to automatically declare all images included using the 
% macro |\includegraphics| from the \pkg{graphics}/\pkg{graphicx} package as 
% external files (see section~\ref{sec:external}). The options \op{external} and 
% \op{autoload} are activated by this option so that the produced |.svx| files 
% are loaded automatically.  An |autoload=false| option after \pkg{graphics} 
% will deactivate this, but then an \cs{svnexternal} macro must be included in 
% all \LaTeX\ files which should take the image revisions into account.\par The 
% \pkg{graphics} package is loaded if this option is active. If this package is 
% needed with some special options it should be loaded by the \LaTeX\ document 
% before \svnmulti.\par  Please note that this feature needs to tie itself into 
% the \pkg{graphics} package and might fail if the internal structure of this 
% package changes in future versions.
%
% If the \op{groups} option is enabled the macro 
% \csi{svngraphicsgroup}\marg{group name} can be used to declare a own group 
% which is used for all the graphic files (also for pgf images, see below).  
% Otherwise they are placed in the group specified by \cs{svnexternalgroup} 
% which defaults to the currently active group.  This macro can be used several 
% times during the document where an empty argument means \emph{no group} and a 
% `|*|' means \emph{current group}.\par Some graphics like logos can appear 
% frequently in a document. Do not count them as part of each chapter they can 
% be ignored using \csi{svnignoregraphic}\marg{file path}. The macro 
% \csi{svnconsidergraphic}\marg{file path} disables this again. Such graphics 
% can be then included manually using an explicit \cs{svnexternal} macro. 
%
% \DescribeOption{pgfimages}
% Identical to like the \op{graphics} option but for the \pkg{pgf} package 
% (implemented against the version from 2008/01/15) with the |\pgfuseimage| and 
% |\pgfimage| macros.  Please also see the notes about package loading and ties 
% mentioned above. 
%
% \DescribeOption{autoload}
% Controls automatic loading of corresponding |.svx| files at the begin of files 
% included using |\input| or |\import|. This avoids the need of putting an 
% \cs{svnexternal} macro in every file just to load the |.svx| files created 
% automatically by the \op{graphics} option. The option \op{external} is 
% activated by \op{autoload}. 
%
% \DescribeOption{table}
% Controls the generation of a table of revisions which can be included using 
% the \cs{tableofrevisions} macro. This table shows the revisions of all files 
% and groups. This needs \op{groups} to work which is activated with \op{table}. 
% Enable \op{subgroups} to include a list of all files per group. See the 
% section~\ref{sec:table} for more information.
%
% \DescribeOption{filehooks}
% This option loads the \pkg{fink}  package and installs at-begin-input-file and 
% at-end-input-file hooks which are  needed for many of the options above. While 
% this option is enabled  automatically if needed it can be also enabled 
% manually to ensure that the  file-local macros are reset to empty values at 
% the begin of each input file.   This prevents the keyword from leaking over 
% from one file to the next.  After every subfile the file-local keyword macros 
% are also restored to the  value of the parent file.
%
% \DescribeOption{autokw}
% This experimental feature allows the automatically extraction of the keyword 
% values from the hidden Subversion working copy database. The database (a text 
% file called `|entries|') is located in the hidden Subversion directory 
% `|.svn|' (or `|_svn|' on some Windows installations) inside every directory 
% which is under VC.
%
% This feature makes an external script like \scr{svn-multi.pl} or even keyword 
% macros redundant as long the files are inside a Subversion working directory.  
% However, this feature does not work if the files are exported (\eg with 
% \texttt{svn~export}) or manually copied and also depends on the used version 
% of Subversion.  Only versions starting with 1.4 (with working copy format 
% version 7) are supported.  Earlier version used a different format for the 
% |entries| file.  Newer versions should be compatible as long the basic format 
% is not changed again.
%
% The experimental status will be lifted after the feature was tested using
% different Subversion versions on different platforms. Please do not hesitate 
% to send error reports to the package author. Minimal examples and information 
% about the used Subversion version and platform are very much appreciated.
%
% This option allows the following values:
% \begin{description}
%   \item[\texttt{false}] Feature is disabled (default).
%   \item[\textnormal{\sffamily No value or \textbf{\texttt{true}} or 
%   \textbf{\texttt{all}}}] The keywords of all files are automatically 
%   extracted.  No \cs{svnid} or \cs{svnidlong} macros or external scripts are 
%   necessary as long the files are inside a Subversion working directory and 
%   not exported.
%   \item[\texttt{ext}] Only the keywords of external files are extracted. This 
%   avoids the need of the \scr{svn-multi.pl} script. The option \op{external} 
%   must be still enabled manually.
% \end{description}
%
% \subsection{Including Subversion Keywords}\label{sec:usage:id}
% Subversion keywords are included using \cs{svnid} or \cs{svnidlong}.  These 
% macros should be written very early in each file, \ie in the preamble of the 
% main document soon after |\documentclass| and |\usepackage{svn-multi}| and as 
% first in \emph{every} subfile before an |\chapter| or similar macro. They do 
% not create any output.  See section~\ref{sec:kwaccess} to learn how to typeset 
% the keyword values.
%
% \DescribeMacro{svnid}{\karg{Id}}
% The macro is for the |Id| keyword and must be written like shown.  A trailing 
% colon with or without spaces after the `|Id|' is also valid but 
% \textbf{everything else} except a valid Subversion string will cause a \TeX{} 
% parse error.  The subversion property |svn:keywords| must be set on all source 
% files and include `|Id|' so that Subversion will expand it at the next commit.
%
% \DescribeMacro{svnidlong}{\ignorespaces
% \\\hspace*{\macrosep}\karg{HeadURL}\ignorespaces
% \\\hspace*{\macrosep}\karg{LastChangedDate}\ignorespaces
% \\\hspace*{\macrosep}\karg{LastChangedRevision}\ignorespaces
% \\\hspace*{\macrosep}\karg{LastChangedBy}}
% Macro for a ``long Id''.  Saves similar values like in `|Id|' but from the 
% above four keywords. The usage of \cs{svnid} or \cs{svnidlong} is a matter of 
% taste. The second is more readable inside the code and results in a nicer date 
% and a full URL, not only the filename. However, both can also be used 
% together.  In this case the \cs{svnid} macro should be come last. Because its 
% revision is not higher (but identical) than the revision of the \cs{svnidlong} 
% macro it does not override its values. This way both the full time zone from 
% the long and the file name from the short id macro can be accessed. Please 
% note that all features from the 2.0 version load the \pkg{fink} package which 
% lets you typeset the current file name anyway using 
% |\finkbase.\finkext|\footnote{The file name in \texttt{\${}Id\$} is always the 
% original Subversion file name while the one given by the \pkg{fink} package is 
% the current file name.  Both could differ if the file got renamed.}.
%
% This macro must be written like seen above while the order of arguments is not 
% meaningfull. The Subversion property |svn:keywords| must be set on all source 
% files with an value which includes `|HeadURL| |LastChangedDate| 
% |LastChangedRevision| |LastChangedBy|' or one of their alternative spellings 
% (\eg `|URL|', `|Rev|', `|Date|', etc.).
%
% Please note that the arguments are read verbatim as long the \op{verbatim} 
% option is not disabled explicitly. Special precaution are taken to allow 
% spaces, newlines and comments direct after the |\svnidlong| and after each of 
% the four arguments. In fact everything not inside braces |{ }| is ignored.
%
% \DescribeMacro{svn}{\kmarg{keyword}}
% \DescribeMacro*{svn*}{\kmarg{keyword}}
% This macro let you typeset svn keywords directly. The dollars will be stripped
% and the rest is typeset as normal text. The star version strips also the space
% before the last dollar.  This macro alone was the very first version of
% |svnkw| and is still included for fast and simple keyword typesetting.
%
% \DescribeMacro{svnkwsave}{\kmarg{keyword}}
% This macro lets you include and save any keyword you like. The keyword can be
% already expanded or not (no value and only ``|:|'' or nothing after the key
% name). This macro is also used internally and does not create any output.
% Please note that the argument is read verbatim and that there should be no
% space between the macro and the argument's left brace.
%
% \subsection{Groups}\label{sec:group}
% Starting with v2.0 files can be grouped together and the keyword values of the
% latest revision of a group can be accessed. Use the \op{groups} option to
% activate these macros.
%
% \DescribeMacro{svngroup}{\marg{group name}}
% This macro declares all following files until the next \cs{svngroup} as part 
% of the given keyword group. It can be placed inside the main file before some 
% |\include|/|\input| macros or inside subfiles before the id macros, \ie direct 
% at the start of the file.
% 
% The changes done by this macro are \TeX\ global, \ie there can't be caught 
% using \TeX\ groups (|{ }|). However, in order to prevent subfiles to change 
% the group of the rest of the parent file the group will be restored to the 
% previous one at the end of each input file.
%
% The latest VC information of a group can be typeset with the |\svnvgXXX| 
% macros or the \cs{svng} macro shown in section~\ref{sec:kwaccess}.
%
% \DescribeMacro{thesvngroup}{}
% Returns the name of the current keyword group.
%
% \DescribeMacro{svnsetcg}{\marg{group name}}
% Normally the |\svncgXXX| macros mentioned below use the last keyword 
% group defined by \cs{svngroup} but this can be changed using the \cs{svnsetcg} 
% macro. The idea behind it is that the currently selected group can be 
% changed locally to the current \TeX\ group for the keyword output macros 
% |\svncgXXX| only while the group for the keyword input macros like \cs{svnid} 
% is unaffected.
%
% To reset the used group to the last one defined by \cs{svngroup} simply use 
% \cs{svnsetcg} with an `|*|' as argument.
%
% \paragraph*{Example 1:} |{\svnsetcg{abc}\svnFullAuthor{\svncgauthor}}|\\ would
% output the full author's name of group \textit{abc}.\par
% \paragraph*{Example 2:} To typeset the three keyword values of group
% \textit{abc} somewhere outside this group use:\\
% |{\svnsetcg{abc}Rev: \svncgrev\\||Date: \svncgdate\\|\\{}
% |Author: \svncgauthor\\}|
% \paragraph*{Example 3:} To typeset the date of group \textit{abc} outside of
% this group in the format of |\today| use: |{\svnsetcg{abc}\svncgtoday}|
% \smallskip
%
% \DescribeMacro{thesvncg}{}
% Returns the name of the current group selected by \cs{svnsetcg}.
%
% \subsubsection{Files as Subgroups}\label{sec:subgroups}
% The group feature could be used to access the version control information of 
% single files anywhere in the document when these are defined as own groups for 
% themselves. Because a file can only be in one group this would not be 
% compatible with the normal usage of the group feature. Therefore a special 
% feature was introduced to automatically or manually define a file as subgroup 
% for itself which does not influence its membership in a normal group.
% \paragraph{Declaration:}
% This feature is enabled by the \op{subgroups} option. All files of the
% document are then automatically declared as extra groups. This can be disabled
% for parts of the document using \csi{svnsubgroupsfalse} and re-enabled
% using \cs{svnsubgroupstrue} macros. The current file can be manually
% declared as extra group with the \cs{svnsubgroup} macro.\par
% \DescribeMacro{svnsubgroup}{}
% This macro declares the current file as subgroup. It is used automatically for 
% every subfile if \op{subgroups} and \csi{svnsubgroupstrue} are enabled.
%
% \paragraph{Exclude/Consider files extensions:}
% The above mentioned automatically group declaration uses an hook which is
% triggered every time another file is read by the document. This unfortunately
% includes other packages, some auxiliary files and font, config and other files
% read in by this packages. An internal filter is in place to ignore this files
% by their file extension. This filter can by modified by the two following
% macros.
% \DescribeMacro{svnignoreextensions}{\marg{comma separated list of extension 
% without leading dot}}
% Tells \svnmulti to ignore the following file extension and never declare files 
% with them as extra groups.
% \DescribeMacro{svnconsiderextensions}{\marg{comma separated list of extension 
% without leading dot}}
% Tells \svnmulti to (re-)consider the following file extension and declare 
% files with them as extra groups if read in.
%
% \paragraph{Typesetting:}
% The keyword information of the subgroups (subfile including any included 
% external files or subsubfiles) can be typeset using the normal group typeset 
% macros mentioned below where the group name is the file path without 
% extension. The keyword information of the |.tex| file alone can be typeset 
% with the full file path including extension.
% \paragraph{Example:} |\svnsetcg{subdir/some_file.tex}\svncgrev| would typeset 
% the revision of the file |some_file.tex| while
% |\svnsetcg{subdir/some_file}\svncgrev| would typeset the latest revision of 
% the same file or any subfile or declared external file included by it.
%
%
% \subsection{Typesetting the Keyword Values}\label{sec:kwaccess}
% The following macros can be used to typeset the keyword values anywhere in the
% document. Please note that not all \LaTeX{} fonts have all special
% characters, \eg `|_|' is not provided in the standard roman font. To proper
% typeset file names and URLs containing these letters you can use either
% teletype font (|\texttt|) or use |{\urlstyle{rm}\svnnolinkurl{...}}| which
% requires the \pkg{hyperref} package.
%
% Like already mentioned \svnmulti knows three scopes of keywords. The first
% contains of the keywords for the complete document which hold the values of
% the most recent committed file and the second contains of the \emph{current}
% or \emph{file local} keywords, \eg the keywords of the current file. Only this
% two are described here while the third scope is described in
% section~\ref{sec:group}.
%
% \DescribeMacro{svnrev}{}
% \DescribeMacro*{svndate}{}
% \DescribeMacro*{svnauthor}{}
% These macros hold the keyword values of the whole document, \ie of the most
% recent revision. They can be used everywhere in every file of the \LaTeX{}
% document, after |\usepackage{svn}| of course. Please see
% section~\ref{sec:date} how to typeset parts of the date.
%
% \DescribeMacro{svnfilerev}{}
% \DescribeMacro*{svnfiledate}{}
% \DescribeMacro*{svnfileauthor}{}
% These macros hold the keyword values of the current \LaTeX{} file, but only if
% it contains a \cs{svnid} or \cs{svnidlong} macro. Otherwise the macros hold
% either zero values or the values of the last file dependent on whether an
% option is enabled which enabled the \pkg{fink} package. Please see
% section~\ref{sec:date} how to typeset parts of the date. See \cs{svnkw} below
% for all other keywords.
%
% \DescribeMacro{svncgrev}{}
% \DescribeMacro*{svncgauthor}{}
% \DescribeMacro*{svncgdate}{}
% These macros return keyword values of the currently selected keyword group.
% In order to hold them robust, which is important to use them in macros like
% \cs{svnFullAuthor}, they do not provide any arguments to select other groups
% than the current one. To access keyword values of other groups use the general
% macro \cs{svng} or change the locally selected keyword group using the macro 
% \cs{svnsetcg}.
%
% \DescribeMacro{svng}{\marg{group name}\marg{key}}
% This macro is a general form of the |\svncgXXX| macro mentioned above.
% The first argument is the requested keyword group, the second one the
% requested keyword in the form of |rev|, |date|, |author|, |year|, etc.. Please
% note that this macro can not be used inside macros like \cs{svnFullAuthor}.
%
%
% \DescribeMacro{svnmainurl}{}
% \DescribeMacro*{svnmainfilename}{}
% The macro \cs{svnmainurl} and \cs{svnmainfilename} hold the URL and the
% filename of the main \LaTeX{file} as long the keywords |HeadURL| or |Id| were
% used in it, respectively.  These can be used to typeset this information
% anywhere in the document which might be more descriptive as the name of the
% current file (which can be typeset with \cs{svnkw}|{HeadURL}| or
% \cs{svnkw}|{Filename}| after \cs{svnid} or \cs{svnidlong}, respectively).
%
% \DescribeMacro{svnsetmainfile}{}
% This will declare the current file as the main LaTeX file by defining the
% above macros. It will automatically be called at the end of the preamble so
% the user normally doesn't have to use it by him- or herself as long it isn't
% needed in the preamble.\par Please note that this macro changes the
% definition of \cs{svnmainurl} and \cs{svnmainfilename} directly without going
% over the auxiliary file. Calling it in several files will make this two macros
% inconsistent.
%
% \DescribeMacro{svnkw}{\marg{keyword name}}
% All keywords saved with \cs{svnid}, \cs{svnidlong} or \cs{svnkwsave} can be
% typeset by this macro which is a holdover from a very early version of this
% package when multiple files where not supported.  It takes one argument which
% must be a subversion keyword name. It then returns the current value of this
% keyword or nothing (|\relax|) when the keyword was not set yet.
% Examples:\\
% \indent\indent |\textsl{Revision: \svnkw{Revision}}|\\
% \indent\indent |URL: \url{\svnkw{HeadURL}}|\\
% In the second example |\url| (\pkg{hyperref} package) is used to add a hyperlink
% and to avoid problems with underscores (|_|) inside the URL.  \svnmulti is
% also providing a macro \cs{svnnolinkurl} which works like |\url| but doesn't
% adds an hyperlink. See the description of this macro for more details.
%
% If the given keyword doesn't exists a package warning is given to allow
% spelling errors to be tracked down. This doesn't work well when \cs{svnkw} is
% used inside |\url|. In this case the warning code will be typeset(!) verbatim
% into the document by |\url|.
%
% \DescribeMacro{svnkwdef}{\marg{keyword name}\marg{value}}
% This macro is used to define the keyword values. This is normally only called
% internally but could be used by the user to override single keywords.  The
% values can then be typeset by \cs{svnkw}.  Note that this macro has no
% influence on the calculation of the latest revision.
%
% Note that for \cs{svnkw} and \cs{svnkwdef} all different names for one keyword
% are valid and result in the access of the same variable. So \eg subversion
% treats |Rev|, |Revision| and |LastChangedRev| the same way and so does this
% macros. You can \eg say |\svnkwdef{Rev}{123}| and then typeset it with
% |\svnkw{Revision}| or |\svnkw{LastChangedRev}| if you like.
%
% \subsubsection*{New in version 2.2. Will change in future versions:}
% \DescribeMacro{ifsvnfilemodified}{\marg{case:~modified}\marg{case:~not 
% modified}}
% \DescribeMacro*{ifsvnmodified}{\marg{case:~modified}\marg{case:~not modified}}
% This two macro can be used to check if either the current or any file was 
% modified after it was last checked into the repository. At the moment (v2.2) a 
% file is marked `modified' if there is either a `|*|' or `|M|' after the 
% revision number, \eg `|$||Rev: 123M $|'. Such an marker is automatically added 
% for exported files (`|svn export|') if there where locally modified, but can 
% also be added manually.
% 
% Future versions of this package might mark files as modified by use of the 
% \op{autokw} option which can read this information out of the working 
% directory Subversion entries.

% \\*[\medskipamount]
% Whenever the date information is read, \ie by
% \cs{svnkwsave}|{LastChangedDate}| \cs{svnkwsave}|{Date}|, \cs{svnidlong} or
% \cs{svnid}, the following macros are set to the appropriate date parts for the
% current file (the |\svnfile...| versions) and for the whole document.
%
% Please note that the hour and timezone are dependent on the keyword which
% defines the date information. The hour will be in UTC aka Zulu-time, \ie
% timezone +0000, when the date comes from the |Id| keyword.
% Otherwise the hour and timezone will be in local time.
% To avoid confusion the |Id| and |Date|/|LastChangedDate| keywords, \eg
% \cs{svnid} and \cs{svnidlong}, should not be intermixed and/or the timezone
% should always be typeset together with the time.
%
% Starting with v1.4 of \svnmulti the timezone macros return the full
% timezone, \ie sign, hour and minute part, \eg |+0100|, not only the sign and
% hour. The new macros % \cs{svntimezonehour}/\cs{svnfiletimezonehour} and
% \cs{svntimezoneminute}/\linebreak[3]\cs{svnfiletimezoneminute} can be used to
% access only the hour including sign or the minute part, respectively.
%
% Older versions of this manual assumed the minute part as always |00| and
% suggested to add it manually if needed: |\svnfiletimezone00| or
% |\svntimezone00|.  In order not to ``break'' documents which followed this
% suggestion this two macros now remove a trailing |00| if present.  However,
% this can be a problem when they are used inside an argument of another macro.
% One solution for this is to redefine them without the |00| removal part:\\
% \begingroup\small
% |\renewcommand{\svntimezone}{\svntimezonehour\svntimezoneminute}|\\
% |\renewcommand{\svnfiletimezone}{\svnfiletimezonehour\svnfiletimezoneminute}|
% \endgroup\par
% To revert to the old (pre-v1.4) definition use:\\
% \begingroup\small
% |\renewcommand{\svntimezone}{\svntimezonehour}|\\
% |\renewcommand{\svnfiletimezone}{\svnfiletimezonehour}|
% \endgroup
% \vspace{1ex}
%
% \DescribeMacro{svntime}{}
% \DescribeMacro*{svnfiletime}{}
% \DescribeMacro*{svncgtime}{}
% This macros return the time part of the date only and simply return the
% corresponding hour, minute and second macros with a colon as separator.
%
% \DescribeMacro{svnpdfdate}{}
% Returns the last changed date of the whole document in a format needed for
% |\pdfinfo|. Can be used like this:\\
% \hbox{}\hfill|\pdfinfo{ /CreationDate (D:\svnpdfdate) }|\hfill\hbox{}\\
% to set the PDF creation date to the last changed date if you use |pdflatex| to
% compile your \LaTeX{} document.
%
% \DescribeMacro{svntoday}{}
% \DescribeMacro*{svnfiletoday}{}
% \DescribeMacro*{svncgtoday}{}
% These macros typeset the document-global, current-file or current-group date,
% respectively, using the format of |\today| which depends on the used language.
% To adjust the language of your document use the \pkg{babel} package.
%
% \subsection{Using Full Author Names}
% If you like to have the full author\footnote{This means subversion authors,
% \eg the persons who commit changes into the svn repository.} names, not only
% the usernames, in your document you can use the following macros. First you
% have to register all authors of the document with \cs{svnRegisterAuthor} and
% then you can write \eg |\svnFullAuthor{\svnauthor}| or
% |\svnFullAuthor{\svnfileauthor}|.
%
% \DescribeMacro{svnRegisterAuthor}{\marg{author}\marg{full name}}
% This macro registers \meta{full name} as full name for \meta{author} (a
% subversion username) for later use with \cs{svnFullAuthor}.
%
% \DescribeMacro{svnFullAuthor}{\marg{author name or macro}}
% \DescribeMacro*{svnFullAuthor*}{\marg{author name or macro}}
% Takes the username as argument and returns the full name if it was registered
% first with \cs{svnRegisterAuthor}, otherwise it returns the given username.
% The star version returns the username in parentheses after the full name.
% This is normally used in one of the following forms:\\
% \hspace*{3em}\cs{svnFullAuthor}|{|\cs{svnauthor}|}|\\
% \hspace*{3em}\cs{svnFullAuthor}|{|\cs{svnfileauthor}|}|\\
% \hspace*{3em}\cs{svnFullAuthor}|{|\cs{svncgauthor}|}|
%
% \subsection{Using Full Revision Names}
% Like the author's also revision names/tags can be registered and used later.
% These macros were implemented on user request and have the drawback that you
% have to guess the next revision number of your document in order to get
% correct results when you like to tag the to-be-checked-in revision.  Please
% note that this has nothing to do with the normal subversion tagging.
%
% \DescribeMacro{svnRegisterRevision}{\marg{revision number}\marg{tag name}}
% This registers \meta{tag name} as tag name for \meta{revision number} for
% later use with \cs{svnFullRevision}.
%
% \DescribeMacro{svnFullRevision}{\marg{revision number or macro}}
% \DescribeMacro*{svnFullRevision*}{\marg{revision number or macro}}
% Takes a revision number coming from a macro like \cs{svnrev}, \cs{svnfilerev}
% or a number as argument and returns the full name if it was registered first
% with \cs{svnRegisterRevision}, otherwise it returns ``Revision \meta{revision
% number}''.  The star version returns also the revision number leaded by `r' in
% parentheses after the tag name, \eg |Name (r123)|.
%
% \subsection{Verbatim URLs with and without Hyperlinks}
% \vspace{-\baselineskip}
% \DescribeMacro{svnnolinkurl}{\marg{macro with returns special text}}
% This macro allows you to write |\svnnolinkurl{\svnkw{HeadURL}}| and get the
% Head URL typeset verbatim. However |\url{|\cs{svnkw}|{HeadURL}}|
% (\pkg{hyperref} package) gives you the same result with a hyperlink. Both
% macros require the \pkg{hyperref} package which is not automatically loaded by
% \svnmulti.  Please load it manually when you like to use \cs{svnnolinkurl}.
%
% Since v1.3 all keywords are read and typeset verbatim so this macro isn't this
% important anymore. However together with \pkg{hyperref}'s |\urlstyle| macro it
% can be used to have keyword values with special characters in roman font,
% which normally doesn't hold letters like `|_|'.
%
% Please note that you can't use \pkg{hyperref}'s |\nolinkurl| because it won't
% expand \cs{svnkw}.
%
% \subsection{Table of Revisions}\label{sec:table}
% Version 2.0 introduces this new feature which allows a overview table to be
% typeset which holds the version control information of all files of the
% document.
%
% \DescribeMacro{tableofrevisions}{}
% If the \op{table} is enabled a table of revision is written into a file called
% \meta{main \LaTeX\ file}|.svt| (|t| for table) which can be included using the
% \cs{tableofrevisions} macro. The table contains the revision information of
% the complete document and of all defined groups.
% If the \op{subgroups} option is set the table will also include the single
% files sorted by group.\par
%
% \subsubsection*{Table Format Macros}
% The |.svt| file is in an general format which uses a lot of macros to format
% the table and the different cells.  This macros should not be used by the user
% directly but rather can be redefined to fit the personal taste.
% Figure~\ref{fig:tablemacros} shows this macros in their position inside the 
% table of revisions.

% \DescribeMacro{svntabgroup}{\marg{group name}}
% Formats the group name.
%
% \DescribeMacro{svntabsubgroup}{\marg{nesting level
% (1,2,3,\ldots)}\marg{subgroup name}}
% Formats a subgroup name. The name is derived from a file name and therefore 
% could contain characters like `|_|' which should be taken into account. The
% macro \cs{svnnolinkurl} can be used for this. Because subgroups can be nested
% a number is provided to tell the nesting depth. This can be used to produce

%
% \subsection{Including Keywords of External Files}\label{sec:external}
% Version 2.0 now supports the inclusion of keywords of external files using the
% following macros and the Perl script \scr{svn-multi.pl}.
%
% \DescribeMacro{svnexternal}{\oarg{group name}\{\{\meta{filea}\}\ignorespaces
% \{\meta{fileb}\}\ldots\{\meta{filex}\}\}}
% Subversion keywords of external files (\eg non-\LaTeX\ files like images or
% even directories) can be included using this macro which awaits a list of
% files, each with the full path relative to the main \LaTeX\ file and each
% enclosed by |{ }|. The files must be under version control by Subversion, of
% course. Use \cs{svnexternalpath} to specify paths to be scanned for this
% files if they are not located relative to the main file.  The requested
% filenames are written into the |.svn| auxiliary file and then processed by the
% external script \scr{svn-multi.pl} which must be executed like described
% below. The appropriate keywords are then written in \meta{source file}|.svx|
% files (|x| like eXternal) which are read in by the same \cs{svnexternal} macro
% at the next \LaTeX\ run. If a group name of `|*|' for the external files is
% specified using the optional argument the keywords will be placed in the same
% keyword group as this macro. The file local macros like \cs{svnfilerev} which
% appear in a source file after \cs{svnexternal} are affected, \ie updated if
% one of the external revision is higher than the one of the source file. This
% makes sense if \eg the included graphics are taken as logical part of a source
% file.
%
% \DescribeMacro{svnexternalpath}{\{\{\meta{patha}\}\ignorespaces
% \{\meta{pathb}\}\ldots\{\meta{pathx}\}\}}
% This macro can be used in the document preamble to declare a set of paths to
% be scanned for files specified with \cs{svnexternal}. This avoids the need to
% provide the path again and again for every file.
% The paths need to be enclosed in |{ }| and must be in Unix style, \ie with
% `|/|' as directory separator and should end with a `|/|'. Windows users should
% just replace all `|\|' with `|/|', \eg `|C:\My dir|' gets `|{C:/My dir/}|'.
%
% \subsection*{Script \hypertarget{script@svn-multi.pl}{\texttt{svn-multi.pl}}}
% The file \scr{svn-multi.pl} which comes with the \svnmulti package is an
% external Perl script which has to be run in the command line or by a \LaTeX\
% development environment/editor like other tools like |Bib|\TeX\ or
% |Makeindex|. A Perl interpreter and a Subversion command line client (|svn|)
% must be installed to execute this script. Both are available for free for all
% major operating systems.\par
% The script should be run inside the document folder in the following order:
% \begin{enumerate}
%  \item Compile \LaTeX\ document, |.svn| file is generated.
%  \item Run \scr{svn-multi.pl} script, |.svx| files are generated.
%  \item Compile \LaTeX\ document, |.svx| files are read in.
% \end{enumerate}
%
% The script can be used with three different sets of arguments and with
% any combination of them. Please note that the word |jobname| stands for
% the main \LaTeX\ file name without the |.tex| extension.
%
% \DescribeScript{svn-multi.pl}{\meta{jobname}}
% As already mentioned in the \cs{svnexternal} description above this script
% reads the requested external filename from the \meta{jobname}|.svn| file. The
% Subversion command line client |svn| is then used to fetch the needed keywords
% which are placed in a \cs{svnidlong} macro inside a \meta{source file}|.svx|
% file. Every single source file which uses \cs{svnexternal} will become its own
% |.svx| file which allows to attach specific external files to one (or more)
% specific source files.
%
% \DescribeScript{svn-multi.pl}{\meta{jobname} [-{}-group \meta{group name}]
% \meta{file(s)} \ldots}
% The second way to use \scr{svn-multi.pl} is to call it with a list of external
% files. A keyword group can be specified using the |--group| \meta{group name}
% option which can placed any number of times between the file names. The group
% is used for all external files listed after the option until the next group is
% specified. All keywords of these files are written in the \meta{jobname}|.svx|
% file and read in by the main \LaTeX\ file if a, possible empty,
% \cs{svnexternal} macro is included. This allows for easy including of many
% external files without specifying them all inside the source file. For example
% \scr{svn-multi.pl}| */*.jpg| (under Linux/Unix) will include the keywords of
% all JPG files in all subdirectories.\par
% It is also possible to do this with a sub-(\LaTeX)-file by calling the script
% on it: \scr{svn-multi.pl}~\mbox{\meta{sub file} \meta{external files for sub
% file}}, which will create/overwrite the \meta{sub file}|.svx| file.  However
% the files given by \cs{svnexternal} in this sub-file will not be honoured in
% this case.
%
% \DescribeScript{svn-multi.pl}{\meta{jobname} [-{}-group \meta{group name}]
% -{}-fls}
% Instead of providing a list of all non-\LaTeX/external files the |--fls|
% option can be used to read this list from the \meta{jobname}|.fls| file. This
% file is produced by the \LaTeX\ compiler when run with the |--recorder| option
% and contains a list of all input and output files. Only input files with a
% relative path are used. A corresponding keyword group can also be specified.
%
% \section{Compile Guide}\label{sec:compileguide}
% A document which uses \svnmulti\ needs to be compiled by \LaTeX\ in the
% following ways depending on the used features.
% ^^A The Figure~\ref{fig:compi} below shows the complete compilation cycle.
%
% \subsection*{Basic Features -- Global and Group Keywords}
% \begin{enumerate}
%   \item Compile document with \LaTeX. The |.svn| file is generated. Document
%     global and group keyword macros are not valid yet.
%   \item Compile document again with \LaTeX. The |.svn| file is read by
%     \svnmulti. Document global and group keyword macros are now valid.
% \end{enumerate}
%
% \subsection*{Table of Revisions}
% \begin{enumerate}
%   \item Compile document with \LaTeX. Document global and group keyword macros 
%   are calculated and written to the |.svt| file.
%   \item Compile document again with \LaTeX. The |.svt| file is read and 
%   typeset by the \cs{tableofrevisions} macro.
% \end{enumerate}
%
% \subsection*{External Files}
% \begin{enumerate}
%   \item Compile document with \LaTeX. The |.svn| file is generated with
%     references to the external files. Document global and group keyword macros
%     are not valid yet. External files are not taken into account.
%   \item Run \scr{svn-multi.pl} with the main base name (main file name without
%     extension) as argument. This generates |.svx| files for each |.tex| file
%     which used \cs{svnexternal}. This files contain the keywords of the
%     external files.
%   \item Compile document again with \LaTeX. The |.svx| files are read by
%     \svnmulti and the |.svn| file is updated to take the new keywords into
%     account. Document global and group keywords macros only hold
%     internal values.
%   \item Compile document again with \LaTeX. The |.svn| file is read by
%     \svnmulti. Document global and group keyword macros are now fully valid.
% \end{enumerate}

%
% \section{Known Issues}\label{sec:issues}
% This section lists some known issues of the \svnmulti package and tries to
% provide some workaround. Please feel free to write \svnmulti author if you
% detect any side effects or other issues causes by this package.
%
% \subsection{Packet \texttt{listings} uses \cs{input}}
% If a file \meta{basename}.\meta{extension} is typeset verbatim using
% |\lstinputlisting|, which uses |\input| to read the file, an existing
% \meta{basename}|.svx| file is also included as part of the listing. This can
% be avoided by code like this:
% \begin{verbatim}
%  {\makeatletter\let\input\@input
%  \lstinputlisting[options]{filename}
%  }
% \end{verbatim}

% \subsection{Definition of init values}
% Initialisation of at least the revision to a numeric value is necessary to not
% break the |\ifnum| tests later in this package. The revision is initialised to
% -2, but will be set to 0 if an unexpanded |$||Rev:$| keyword is read. This way
% it can be tested if a file had any keyword macros or not.\par
% Note that there a two different macros for the document global keywords:\par
% The user level |\svn|\meta{kw} macros hold the global value and are only valid
% after a \LaTeX\ run. They are initialised here and defined in the |.svn|
% file which is read at the end of the package if it exists and written at the
% end of the document.\par
% The internal macros |\@svn@|\meta{kw} store the oldest (i.e. highest revision)
% keywords read so far from the \cs{svnid} and \cs{svnidlong} macros. They
% change during the document and are used to produce the values of the
% |\svn|\meta{kw} macros when the |.svn| file is written.\par
% Group wide macros are initialised when the group is first defined and have
% three different macros: |\svng@|\meta{group}|@|\meta{kw} (defined in |.svn|),
% |\@svng@|\meta{group}|@|\meta{kw} (accumulator) and also an access
% macro |\svncg|\meta{group} which uses
% |\svn@g|\meta{current group}|@|\meta{kw}.

% \subsection{Keyword check and strip macros}
% The following macros are used to test whether the given keywords are fully
% expanded or not.
% Subversion supports unexpanded keywords as input with or without colon and
% with or without trailing space(s), \ie a:~|$KW$|, b:~|$KW:$| or c:~|$KW: $|.
% To avoid \LaTeX{} syntax errors in this pre-commit state the keyword is
% checked by the following macros. Unexpanded keywords result in an empty value.
% Also leading and trailing spaces are removed.
%
% \begin{macro}{\svn@checkcolon}[2]{key}{potential value, might be empty}
% Checks if the keyword contains a colon. It is called by \cs{svnkwsave@read}
% with a trailing |:\relax| so that \#2 will be empty if there is no earlier
% colon or will hold the value with this trailing colon otherwise.
% The first case means that the keyword is unexpanded without colon (case a)
% which leads to an empty value. In the second case \cs{svn@stripcolon} is
% called to strip the colon and surrounding spaces. The final value is
% returned by |\svn@value|.
%    \begin{macrocode}
\def\svn@checkcolon#1:#2\relax{%
  \svn@ifempty{#2}%
    {\svnkwdef{#1}{}}%
    {\svn@stripcolon#2\relax\svnkwdef{#1}{\svn@value}}%

%    \end{macrocode}
% \end{macro}

% \begin{macro}{\svn@stripcolon}[1]{potential value}
% Strips the previous added colon (for \cs{svn@checkcolon}).
% The remaining argument is checked if it's empty (case b) or only a space
% (case c). Otherwise the keyword is expanded and \cs{svn@stripspace} is
% called to strip the spaces.
