%  It remembers the previous version number, also when
%  the |.aux|-file is corrupted (due to errors in the
%  \LaTeX{} run).\\ \small This file and the package:\

%  \section{Introduction}
%  \DescribeMacro\version
%  This package provides one command, |\version|, which
%  puts a version number where it appears.  The version
%  number is increased each time \LaTeX{} is run,
%  \textit{i.e.}\ it numbers the |.dvi|-file.  If the
%  package is loaded but the command |\version| is not
%  issued, the present version number is preserved. 
%  Numbering can be incremented at three different levels: 
%  units, tenths, and hundreds.  A change between two of these 
%  is obtained by changing the package option.  After a change
%  of steplength, the previous version number is
%  incremented with the new steplength.  The version number
%  can be held constant by using the command
%  \DescribeMacro\keepversion
%  |\keepversion|; this enables the version number to be
%  printed without being increased.  (|\keepversion| can be
%  \DescribeMacro\stepversion
%  overridden by the command |\stepversion|.) 
%  
%  \section{Userguide}
%  \subsection{Requirements}     
%  The file |vrsion.sty| must be available in the user's
%  |TEXINPUTS| directories. It requires \LaTeXe{} of
%  1995/12/01 (or newer). 
%  
%  \subsection{Usage}
%  The package is included by stating \\
%  |  \usepackage[|\textit{option}|]{vrsion}|\\
%  \DescribeMacro{one} \DescribeMacro{ten}
%  \DescribeMacro{hundred} \DescribeMacro{xspace}
%  in the document preamble.  It can take one of the 
%  options |one|, |ten|, and |hundred|, and in addition |xspace|. 
%  To produce a 
%  version number anywhere in your document you issue the 
%  \DescribeMacro\version
%  command |\version| at the desired place in your \LaTeX{}
%  input file.\footnote{Notice that the text ``version''
%  is \textit{not} produced by the
%  \texttt{\textbackslash version} command.}  The 
%  version number will then be incremented  each time you
%  run \LaTeX{} on the file.  The command |\version| is 
%  robust.\footnote{Thanks to Timothy Robertson 
%  (\texttt{timothyr@cmbr.phys.cmu.edu}) for bringing my 
%  attention to the problem of \texttt{\textbackslash version} 
%  being fragile.}  Depending on the  option
%  used, the version number will be an integer (no  option
%  or option |one|), a number with one decimal  (option
%  |ten|), or a two-decimal number (option  |hundred|). 
%  If the option |xspace| is specified, the \textsf{xspace} 
%  package is loaded and its features are benefited from.  (If 
%  the \textsf{xspace} package is loaded by a separate 
%  |\usepackage| statement or by another package, its features 
%  are used by \textsf{vrsion}.)  
%  
%  When changing from one option (of |one|, |ten|, or |hundred|) 
%  to another,  the previous
%  format of the version number will be  changed according
%  to the new option.  If a smaller  increment is
%  specified, the next increment will simply  append one
%  digit |1| to the old version number; \textit{e.g.}\  a
%  change from option |ten| to |hundred| after version  3.2
%  will result in version 3.21.  If a larger  increment is
%  specified, the old version number will be truncated
%  before the increment; \textit{e.g.}\  a change from     
%  option |hundred| to |ten| after version 3.25
%  will  result in version 3.3.  You should (normally) not
%  use the  command |\version| more once in a document. 
%  The version number is stored in a file with  extension
%  `|vrs|' in the default directory.  (The  full name of this
%  file is |\jobname.vrs|.) 
%  
%  If you want your document to contain a version 
%  number without having it incremented each time
%  you run \LaTeX{}, you should issue the command 
%  \DescribeMacro\keepversion
%  |\keepversion| in the document (preamble).  This 
%  switches off the incrementation mechanism and prevents
%  the package from writing an updated |.vrs|-file.  
%  The |\keepversion| command can be cancelled at 
%  any later place in the document by issuing the 
%  \DescribeMacro\stepversion
%  command |\stepversion|.  The action taken by the 
%  |\version| command is determined by which of these
%  two was last issued.
%  
%  Typically, you would load the \textsf{vrsion} package 
%  with the desired option and use the command 
%  |\version| where you want your document to state 
%  its version number.  Normally, you would have the
%  |\keepversion| command in the preamble, but 
%  comment it out on the first \LaTeX{} run when you 
%  prepare to print a new version and then have the 
%  |\keepversion| in action during the \LaTeX{} runs 
%  needed to resolve the references.
%  
%  When it is desired to repeat the version number
%  several times in a document, issue a 
%  |\keepversion| directly after the first use of 
%  |\version|.  This will then produce the same 
%  version number at all occurrences; and the version
%  number will be incremented according to the use of 
%  |\keepversion| in the preamble.  
%  
%  If the increase of the version number is to occur 
%  at any stage later than the fist occurrence of 
%  |\version|, the occurrence of |\version| 
%  which is to increase the version number should be
%  preceeded by a |\stepversion| command (and 
%  followed by |\keepversion| to prevent further
%  increments).  The author can not think of any 
%  reason why this should be desired, but it can be 
%  achieved anyway$\ldots$
%  
%  \subsection{Known Problems}
%  \begin{itemize}
%  \item At the present (\filedate), \textsf{vrsion} does not 
%  work properly with neither the \textsf{letter} nor the 
%  \textsf{scrlettr} document classes.  
%  \item The |\vrsion| package is not working properly with the
%  |\include{|\textit{file}|}| command; use |\input{|\textit{file}|}| 
%  instead.
%  \item If the command |\version| is issued more than once
%  in a document,   the version number will be incremented
%  at each occurrence and produce   different version
%  numbers at the different occurrences (unless  
%  |\keepversion| is in effect).  This may typically be a 
%  problem if you use |\version| in the page header or footer. 
%  This is avoided if |\keepversion| is issued somewhere on the 
%  second page.
%  \end{itemize} 
%  
%  \section{History}
%  The first version of the package was released in late 
%  December of 1994.  The package
%  was created with useful help and ideas from Johan
%  Fr\"oberg (\texttt{emgion@physchem.kth.se}). \par
%  The \textsf{vrsion} package version \fileversion{} has 
%  been tested with \LaTeXe{} of 
%  1996/06/01 running   
%  \TeX{} 3.14159 under OpenVMS. Please send bug reports
%  (see below), corrections, additions, suggestions,
%  \textit{etc.}\ to me at \texttt{matsd@physchem.kth.se}. 
%  
%  \subsection{Changes from previous versions}
%  
%  In \textsf{vrsion} (|version|) version 1.0 the macro 
%  |\@skrivner| caused extra 
%  space to be inserted in front of the version number.  With 
%  \textsf{vrsion} version 1.1 and later this is avoided.  
%  
%  In version 1.1 the \textsf{vrsion} package had incompatibility 
%  problems with the \textsf{babel} package.\footnote{Thanks to Peter 
%  Ryder (\texttt{ryder@theo.physik.uni-bremen.de}) for 
%  bringing my attention to this problem.}  With \textsf{vrsion} 
%  version 1.2 this problem is eliminated.  Also, the command 
%  |\version| has been made robust.  
%  
%  In version 1.3, some adjustments to changes in the \textsf{babel} 
%  package have been made,\footnote{Thanks to Cornelius C.\ Noack 
%  (\texttt{noack@physik.uni-bremen.de}) for bringing my attention to 
%  the re-appearance of the \textsf{babel} incompatibility.}   
%  if the \textsf{xspace} package is 
%  loaded, its features are made use of.  Also, some problems with 
%  |\maketitle| issuing extra blank page(s) have been 
%  eliminated,\footnote{Thanks to Ludek Matyska (\texttt{ludek@muni.cz})
%  for pointing out this problem.}   it 
%  seems (at least for the \textsf{article}, \textsf{report}, and 
%  \textsf{book} classes).  Furthermore, some cosmetics 
%  in the installation routine have been added.
%  
%  Version 1.4 eliminated an incompatibility with 
%  the \textsf{koma-script} package. The incompatibility was that 
%  some features of \textsf{koma-script}'s version of the 
%  |\maketitle| command were lost when \textsf{vrsion} was 
%  loaded.\footnote{Thanks to Christofer P.\ Baron 
%  (\texttt{baron@iml.fgh.de}) for bringing my attention to this 
%  problem.}  Furthermore, some |\typeout| statements have been 
%  removed and the processing order of some of the macro 
%  definitions has been changed.  
%  
%  \section{Sending a Bug Report}
%  \textsf{vrsion} is most likely to contain bugs.
%  Reports of bugs in the package are most welcome.  
%  When filing a bug report,
%  please take the following actions:
%  \begin{enumerate}
%  \item Ensure your problem is not due to your inputfile;
%  \item Ensure your problem is not due to 
%     your own package(s) or class(es);
%  \item Ensure your problem is not covered in the section 
%     ''Known Problems'' above;
%  \item  Try to locate the problem by writing a minimal 
%     \LaTeX{} input file which reproduces the problem.  
%     Include the command\\ 
%     |  \setcounter{errorcontextlines}{999}|\\ 
%     in your input;
%  \item Run your file through \LaTeX ;
%  \item Send a description of your problem, the input file 
%     and the log file via e-mail to:\\  \hspace*{5mm}
%     \texttt{matsd@homenet.se}.

%  \section{The Code} 
%  For the interested reader(s), here is a short description 
%  of the code.
%
%  First, the package should identify itself:
% \iffalse
%<*paketkod>
% \fi
%    \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}[1995/12/01]
\ProvidesPackage{vrsion}%
  [1997/02/22 version numbering of LaTeX files (v.1.41).]
%    \end{macrocode}
%  \par Some counters and booleans used 
%  are to be defined first.  Also the user commands 
%  |\keepversion| and |\stepversion|, which only (re-)set 
%  the |Keepversion| boolean, are defined.
%    \begin{macrocode}
\newcounter{versionnr}
\newcounter{versionnrten}[versionnr]
\newcounter{versionnrhundred}[versionnrten]
\@addtoreset{versionnrhundred}{versionnr}
\newif\ifKeepversion \Keepversionfalse
\newif\ifxspc \xspcfalse
\newcommand{\keepversion}{\global\Keepversiontrue}
\newcommand{\stepversion}{\global\Keepversionfalse}
%    \end{macrocode}
%  \par Next, the options are declared.  The declaration of
%  option |one| is the default version of the |\version| 
%  macro.  If the boolean 
%  |Keepversion| (set by the command |\keepversion|) is 
%  true, no increase of the version number is preformed, 
%  nor is anything written to the |.vrs|-file.  The command 
%  |\@skrivner| is responsible for writing the |.vrs|-file  
%  (``skriv ner'' is Swedish for ``write down'').
%    \begin{macrocode}
\DeclareOption{one}{%
\DeclareRobustCommand{\version}{%
  \ifKeepversion \else 
    \stepcounter{versionnr}% 
    \@skrivner
  \fi
  \theversionnr%
  \@ifundefined{xspace}{}{\xspace}%
}
}
%    \end{macrocode}
%  The |ten| option modifies the |\version| command to 
%  produce a decimal number and steps the integer version 
%  number if the decimal part reaches 10.  
%    \begin{macrocode}
\DeclareOption{ten}{%
  \DeclareRobustCommand{\version}{%
    \ifKeepversion \else
      \stepcounter{versionnrten}%
      \ifnum\theversionnrten=10\stepcounter{versionnr} \fi
      \@skrivner
    \fi
    \theversionnr .\theversionnrten%
    \@ifundefined{xspace}{}{\xspace}%
  }
}
%    \end{macrocode}
%  The option |hundred| does the same as |ten|, but with 
%  a two-decimal number.
%    \begin{macrocode}
\DeclareOption{hundred}{%
  \DeclareRobustCommand{\version}{%
    \ifKeepversion \else 
      \stepcounter{versionnrhundred}%
      \ifnum\theversionnrhundred=10\stepcounter{versionnrten} \fi
      \ifnum\theversionnrten=10\stepcounter{versionnr} \fi
      \@skrivner
    \fi
    \theversionnr .\theversionnrten\theversionnrhundred%
    \@ifundefined{xspace}{}{\xspace}%
  }
}
%    \end{macrocode}
%  The |xspace| option, which only forces the \textsf{xspace} package 
%  to be loaded, is quite short in the code:
%    \begin{macrocode}
\DeclareOption{xspace}{\global\xspctrue}
%    \end{macrocode}
%  All other options which may be specified are to be 
%  ignored:
%    \begin{macrocode}
\DeclareOption*{\OptionNotUsed}
%    \end{macrocode}
%  \par Now we can process the options, and -- if requested --  load 
%  the \textsf{xspace} package.
%    \begin{macrocode}
\ExecuteOptions{one}
\ProcessOptions
\ifxspc\RequirePackage{xspace}\fi
%    \end{macrocode}
%  \par Now the task is to define the internals.  The macro 
%  |\vrsFile| simply holds the name of the |.vrs|-file to 
%  use.  The macro |\@skrivner| writes the version number 
%  counters to a file
%  in a format which is easy to deal with in 
%  \LaTeX{}, a name-wise change\footnote{This was nessecary 
%  to make \texttt{vrsion} compatible with \textsf{babel}.} 
%  of the the ordinary |\label| format.  The internal 
%  macro |\@vrs| is used to avoid problems with label 
%  change warnings and to avoid trouble with missing 
%  version number information in the |.aux|-file when 
%  |\keepversion| is used.  As an aid, the dummy-counter 
%  |VrsNr| is used.
%    \begin{macrocode}
\def\vrsFile{\jobname.vrs}
\newwrite\@vrs
\newcounter{VrsNr}
\def\@skrivner{%
  \setcounter{VrsNr}{\@partaux}%
  \addtocounter{VrsNr}{1}%
  \let\@vrs=\theVrsNr%
  \immediate\openout\@vrs\vrsFile%
  \immediate\write\@vrs{\relax}%
  \immediate\write\@vrs{%
    \string\vrslabel{versionsnummer}{{\theversionnr}{\thepage}}}%
  \immediate\write\@vrs{%
    \string\vrslabel{versionsnummertio}{{\theversionnrten}{\thepage}}}%
  \immediate\write\@vrs{%
    \string\vrslabel{versionsnummerhundra}{{\theversionnrhundred}{\thepage}}
}%
  \immediate\closeout\@vrs{}%
}
%    \end{macrocode}
%  \par\textsf{babel} compatibility 
%  is obtained by defining special |\label| and |\ref| commands.
%    \begin{macrocode}
\@ifundefined{bbl@ref}{\let\vrsref=\ref}{\let\vrsref=\bbl@ref}
\@ifundefined{bbl@newlabel}{\let\vrslabel=\newlabel}%
{\let\vrslabel=\bbl@newlabel}
%    \end{macrocode}
%  \par If it exists, the file |\jobname.vrs| should 
%  be read, and the counters set accordingly.  If this file
%  is missing, the counters should be zero.
%    \begin{macrocode}
\IfFileExists{\vrsFile}{\@@input\vrsFile%
    \setcounter{versionnr}{\vrsref{versionsnummer}}%
    \setcounter{versionnrten}{\vrsref{versionsnummertio}}%
    \setcounter{versionnrhundred}{\vrsref{versionsnummerhundra}}%
  }{%
    \typeout{No file \vrsFile.}%
    \setcounter{versionnr}{\z@}%
    \setcounter{versionnrten}{\z@}%
    \setcounter{versionnrhundred}{\z@}%
}
%    \end{macrocode}
%  \par To prevent |\maketitle| from creating extra blank pages, 
%  some commands from the \LaTeXe{} kernel have to be slightly 
%  modified.  To make sure we use the desired definitions, the 
%  changes are issued in an |\AtBeginDocument| command.  (The 
%  changes are that a few |\newpage| commands have been removed and 
%  that a |\cleardoublepage| has been removed for the \textsf{book} 
%  class.)  To cope with the incompatibility of the 
%  \textsf{koma-script} package, different modified definitions are 
%  used.  Which is to be used is tested in an |\@ifundefined| 
%  statement.
