+
+1 INTRODUCTION
+==============
+
+This package allows to count the number of used registers (counter, dimen,
+skip, muskip, box, token, input, output, math families, languages,
+insertions). Therefore the according \count is read. While \count10 should be
+the number of the counters, \count11 the one of the dimens and so on,
+it is possible to use option proof, in which case a new one of each register
+is used and looked at \the\allocationnumber, and this is compared to the
+number determined by reading the \count. The result for each register is
+compared to the maximum available number of the respective register
+(comparison independent of usage of option proof).
+
+
+2 DOWNLOAD
+==========
+
+`regstats' is available on CTAN:
+  CTAN:macros/latex/contrib/regstats/
+
+Also a ZIP file is provided that contains the files, already
+sorted in a TDS tree (should become available on CTAN soon):
+  CTAN:install/macros/latex/contrib/regstats.tds.zip
+
+`CTAN:' means one of the `Comprehensive TeX Archive Network'
+nodes or one of its mirrors. This is explained in
+  http://www.tex.ac.uk/cgi-bin/texfaq2html?label=archives
+
+The CTAN stuff will be mirrored automatically from the
+ftp server, so
+  ftp://ftp.tug.org/pub/tex/regstats/
+corresponds to
+  CTAN:macros/latex/contrib/regstats/
+
+
+3 INSTALLATION
+==============
+
+Installation with ZIP file in TDS format
+----------------------------------------
+The ZIP file `regstats.tds.zip' contains the files sorted
+in a TDS tree. Thus you can directly unpack the ZIP file
+inside a TDS tree.
+(See CTAN:tds.zip for an explanation of TDS.)
+Example:
+  cd /...somewhere.../texmf
+  unzip /...downloadpath.../regstats.tds.zip
+Do not forget to refresh the file name database of this
+TDS tree.
+Example:
+  texhash /...somewhere.../texmf
+
+Manual installation
+-------------------
+a) Download the regstats files from CTAN or the TUG server.
+   If necessary, unpack them.
+b) Generate the package and driver files:
+     tex regstats.ins
+c) Install the file `*.sty' in your TDS tree:
+     cp *.sty TDS:tex/latex/regstats/
+   Replace `TDS:' by the prefix of your TDS tree
+   (texmf directory).
+d) Copy the documentation files to
+   "TDS:doc/latex/regstats/":
+   README, regstats.pdf, regstats-example.tex,
+   regstats-example.log, regstats-example.pdf.
+e) Update the databases if necessary, e.g. for teTeX:
+     mktexlsr .../texmf
+
+
+4 ADDITIONAL PACKAGES
+=====================
+
+regstats loads other packages:
+* kvoptions, CTAN:macros/latex/contrib/oberdiek/kvoptions.dtx
+* atveryend, CTAN:macros/latex/contrib/oberdiek/atveryend.dtx
+which again load other packages
+(see the result of the \listfiles command in the log-file
+ of the example).
+
+
+5 PACKAGE COMPATIBILITY
+=======================
+
+regstats should be loaded last (but can be loaded earlier).
+
+6 AUTHOR/MAINTAINER
+=====================
+
+* Hans-Martin Münch
+
+
+7 BUG REPORTS
+==============
+
+A bug report should contain:
+* Comprehensive problem description. This includes error or
+  warning messages.
+  * \errorcontextlines=\maxdimen can be added in the
+    TeX code to get more informations in TeX error messages.
+* Minimal test file that shows the problem, but does not
+  contain any unnecessary packages and code.
+* Used drivers/programs.
+* Version information about used packages and programs.
+  * If you are using LaTeX, then add "\listfiles". Then
+    a list of version informations is printed at the end
+    of the LaTeX run.
+* Please no other files than the minimal test file.
+  The other files .log, .dvi, .ps, .pdf are seldom
+  necessary, so send them only on request.
+* Please .zip or .tar.gz your file(s) before sending them!

+% \section{Introduction}
+%
+% \indent This \LaTeX\ package allows to count the number of used registers
+% (counter, dimen, skip, muskip, box, token, input, output,
+% math families, languages, insertions).
+% Therefore the according |\count| is read. While |\count10| should be the number
+% of the counters, |\count11| the one of the dimens and so on, it is possible to use
+% option |proof|, in which case a new one of each register is used and looked at
+% |\the\allocationnumber|, and this is compared to the number determined by reading
+% the |\count|. The result for each register is compared to the maximum available
+% number of the respective register
+% (comparison independent of usage of option |proof|).\\
+%
+% \bigskip
+%
+% \section{Usage}
+%
+% \indent Just load the package placing
+% \begin{quote}
+%   |\usepackage[<|\textit{options}|>]{regstats}|
+% \end{quote}
+% \noindent in the preamble of your \LaTeXe\ source file. The resulting message
+% will be presented at the end of the compilation messages at the screen and in
+% the \xfile{log} file.
+%
+% \subsection{Option}
+% \DescribeMacro{option}
+% \indent The \xpackage{regstats} package takes the following option:
+%
+% \subsubsection{proof\label{sss:proof}}
+% \DescribeMacro{proof}
+% \indent When option \texttt{proof} (or \texttt{proof=true}) is choosen,
+% a new one of each register is used and looked at |\the\allocationnumber|,
+% and this is compared to the number determined by reading the |\count|.
+% The default is \texttt{proof=false}.
+%
+% \section{Alternatives\label{sec:Alternatives}}
+%
+% \begin{description}
+% \item[-] \xpackage{regcount}, 1999/08/03, v1.0, by \textsc{Jean-Pierre F. Drucbert},
+%   provides the command |\rgcounts|, which can write the numbers of used registers
+%   into the \xfile{log} file anywhere (not only at the end) and does this automatically
+%   |\AtBeginDocument| and |\AtEndDocument| (but not |\AtVeryVeryEnd|). The number of
+%   allocated insertions is \emph{wrong} in my opinion, because these are not numbered
+%   $1, 2,\ldots$, but start at a high number, which is then decreased. The package is
+%   compatibel with the \xpackage{regstats} package (i.\,e. you can use both at the same
+%   time in one document) and available at \url{http://www.ctan.org/pkg/regcount}.
+%
+% \item[-] One can manually search for the last appearance of
+%   |\count|, |\dimen|, |\skip|, |\muskip|, |\box|, |\toks|, |\read| (input),
+%   |\write| (output), |\mathgroup| (math familiy), |\language|, and |\insert|,
+%   and find the according number there.
+% \end{description}
+%
+% \bigskip
+%
+% \noindent (You programmed or found another alternative,
+%  which is available at \CTAN{}?\\
+%  OK, send an e-mail to me with the name, location at \CTAN{},
+%  and a short notice, and I will probably include it in
+%  the list above.)

+              Counting used registers (HMM)]
+
+%    \end{macrocode}
+%
+% A short description of the \xpackage{regstats} package:
+%
+%    \begin{macrocode}
+%% Allows to count the number of used registers
+%% (counter, dimen, skip, muskip, box, token, input, output,
+%%  math families, languages, insertions)
+%% and compare these to the maximum available number of such registers.
+
+%    \end{macrocode}
+%
+% We need the \xpackage{kvoptions} and \xpackage{atveryend} packages
+% by \textsc{Heiko Oberdiek}:
+%
+%    \begin{macrocode}
+\RequirePackage{kvoptions}[2010/12/23]% v3.10
+\RequirePackage{atveryend}[2011/04/23]% v1.7
+
+%    \end{macrocode}
+%
+% A last information for the user:
+%
+%    \begin{macrocode}
+%% regstats may work with earlier versions of LaTeX and these
+%% packages, but this was not tested. Please consider updating
+%% your LaTeX and packages to the most recent version
+%% (if they are not already the most recent version).
+
+%    \end{macrocode}
+%
+% \indent See subsection~\ref{ss:Downloads} about how to get them.\\
+%
+% We process the option:
+%
+%    \begin{macrocode}
+\SetupKeyvalOptions{family=regstats,prefix=regstats@}
+\DeclareBoolOption{proof}% \regstats@proof
+\ProcessKeyvalOptions*
+
+%    \end{macrocode}
+%
+% We try to determine, whether \eTeX\ is available:
+%
+%    \begin{macrocode}
+\newif\ifetex
+\begingroup\expandafter\expandafter\expandafter\endgroup
+\expandafter\ifx\csname eTeXversion\endcsname\relax
+ \etexfalse
+\else
+ \etextrue
+\fi
+
+\ifetex
+  \PackageInfo{regstats}{e-TeX found.}
+\else
+  \PackageWarning{regstats}{Could not find e-TeX.\MessageBreak%
+    That can mean that e-TeX was disabled or\MessageBreak%
+    that your distribution of TeX does not contain e-TeX.\MessageBreak%
+    Some packages will not work without e-TeX,\MessageBreak%
+    but should give according messages.\MessageBreak%
+   }
+\fi
+
+%    \end{macrocode}
+%
+% |\AtVeryEndDocument| we write to |\AtVeryVeryEnd|, thus the code will be executed
+% quite late during the compilation. We define a new command to determine the
+% sigular/plural form.

+% \DescribeMacro{regstats.dtx}
+% For unpacking the |regstats.dtx| file and constructing the documentation it is required:
+% \begin{description}

+% \end{description}
+%
+% \DescribeMacro{regstats.sty}
+% The \texttt{regstats.sty} for \LaTeXe\ (i.\,e. all documents using
+% the \xpackage{regstats} package) requires:
+% \begin{description}
+% \item[-] \TeX Format \LaTeXe, \url{http://www.CTAN.org/}
+%
+% \item[-] package \xpackage{kvoptions}, 2010/12/23, v3.10,\\
+%           \CTAN{macros/latex/contrib/oberdiek/kvoptions.dtx}
+% \item[-] package \xpackage{atveryend}, 2011/04/23, v1.7,\\
+%           \CTAN{macros/latex/contrib/oberdiek/atveryend.dtx}
+% \end{description}
+%
+% \DescribeMacro{regstats-example.tex}
+% The \texttt{regstats-example.tex} requires the same files as all
+% documents using the \xpackage{regstats} package, i.\,e. the ones
+% named above and additionally:
+% \begin{description}
+% \item[-] class \xpackage{article}, 2007/10/19, v1.4h, from \xpackage{classes.dtx}:\\
+%           \CTAN{macros/latex/base/classes.dtx}

+% \item[-] package \xpackage{regstats}, 2011/05/16, v1.0b,\\
+%           \CTAN{macros/latex/contrib/regstats/regstats.dtx}\\
+%   (Well, it is the example file for this package, and because you are reading the
+%    documentation for the \xpackage{regstats} package, it can be assumed that you already
+%    have some version of it -- is it the current one?)
+% \end{description}

+% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
+% TDS installing feature, then some files can already be in the right
+% place, see the documentation of \docstrip.
+%
+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution (\teTeX, \mikTeX,\dots) relies on file name
+% databases, you must refresh these. For example, \teTeX\ 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{regstats.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 this
+% 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 regstats.dtx
+%makeindex -s gind.ist regstats.idx
+%pdflatex regstats.dtx
+%makeindex -s gind.ist regstats.idx
+%pdflatex regstats.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \subsection{Compiling the example}
+%
+% The example file, \textsf{regstats-example.tex}, can be compiled via\\
+% |(pdf)latex regstats-example.tex|.\\
+%
