+% \section{Introduction}
+% \indent This package is kind of an add-on to my \textsf{pagesLTS} package,
+% but because that already uses some resources and computing the
+% number of sheets of paper or the paper mass probably is not
+% needed so often, this was made into a separate package.\\
+% \indent It allows to compute the number of sheets of paper needed to print a document
+% (usefull when the paper is running out)
+% as well as the mass of that printed version of the document,
+% usefull e.\,g. when sending it by mail to determine the postage.\\
+% \indent \textbf{Warning/Disclaimer}: The mass of (printer's) ink has to be added
+% (and that of envelope, address sticker, stamps,...).
+% So, this is only an estimation without guarantee --
+% do not sue me, if you have got to pay excess postage!\\
+% \indent Further this package allows to compute
+% \textquotedblleft \textit{base} to the power of \textit{exponent}\textquotedblright
+% \ inside \LaTeX.\\
+% \indent The name \textsf{papermas} is short for paper mass but written with only one \textsf{s},
+% because some software has problems with names with more than eight letters.\\
+% It is \textsf{mass} and gives a reault in grammes $\left[ \unit{g}\right]$,
+% because the weight $F=m\cdot g$ (really $\overrightarrow{F}=m\cdot \overrightarrow{g}$)
+% $\left[ \unit{N}\right]$ would need the knowledge about the gravitational acceleration
+% $g$ (depending on place and time, in central Europe approximately $9.81\unit{m}/\unit{s}^{2}$)
+% and give a result in \textsc{Newton}, which probably is not very usefull.
+%
+% \pagebreak
+%
+% \section{Usage}
+%
+% \indent Just load the package placing
+% \begin{quote}
+% |\usepackage[<|\textit{options}|>]{papermas}|
+% \end{quote}
+% \noindent in the preamble of your \LaTeXe\ source file
+% (preferrrably after calling the \textsf{pagesLTS} package).\\
+% Because the \textsf{pagesLTS} package is used to get the total
+% number of pages, please place a |\pagenumbering{...}| with
+% appropriate argument (e.\,g.~arabic, roman, Roman, fnsymbol,
+% alph, or Alph) right behind |\begin{document}| (see
+% documentation of \textsf{pagesLTS} package).\\
+% Now you can say
+% \begin{verbatim}
+% This document consists of $\arabic{pagesLTS.pagenr}$~pages.
+% When printing $\papermaspagespersheet$~pages on one sheet of
+% paper, $\papermassheets$~sheets will be needed. For
+% ISO~A~\papermasformat\ paper of $\papermasmasss \unit{g}\unit{m}^{-2}$
+% specific mass, the printout will have a mass of about
+% $\papermasstotal \unit{g}$.
+% \end{verbatim}
+% to get e.\,g.
+% \begin{quote}
+% This document consists of $101$~pages.
+% When printing $4$~pages on one sheet of
+% paper, $26$~sheets will be needed. For
+% ISO~A~4 paper of $80\unit{g}\unit{m}^{-2}$
+% specific mass, the printout will have a mass of about
+% $130\unit{g}$.
+% \end{quote}
+%
+% \subsection{Options}
+% \DescribeMacro{options}
+% \indent The \textsf{papermas} package takes the following options:
+%
+% \subsubsection{format\label{sss:format}}
+% \DescribeMacro{format}
+% \indent Option |format| wants to know the ISO~A\ldots format
+% of the paper used for printing, i.\,e. |format=4| means ISO~A4
+% paper format (which is also the default).
+%
+% \subsubsection{masss\label{sss:mass}}
+% \DescribeMacro{masss}
+% \indent Option |masss| wants to know the specific (therefore the third~s)
+% mass of the paper used for printing in $\unit{g}/\unit{m}^{2}$.
+% The default is |masss=80|, i.\,e. $80\unit{g}/\unit{m}^{2}$.
+%
+% \subsubsection{pagespersheet\label{sss:pagespersheet}}
+% \DescribeMacro{pagespersheet}
+% \indent Option |pagespersheet| wants to know, how many
+% pages are to be printed on one sheet of paper.
+% |pagespersheet=2| could mean duplex printing or printing two pages
+% on one side of paper while keeping the back side blank. This
+% does not influence the real printing process! So, if this number
+% differs from the one chosen for printing, the result will be wrong,
+% of course.
+%
+% \section{Alternatives\label{sec:Alternatives}}
+%
+% For determining the number of pages (not sheets of paper)
+% instead of the \textsf{pagesLTS} package the alternatives listed
+% in the description of that package could be used, but then
+% the according code in this package would need to be changed
+% (and also e.\,g. the |ifcounter| used here).\\
+% With the \textsf{totpages} package optionally the number of
+% sheets of paper needed to print the document can be computed, too.\\
+% (See \textsf{pagesLTS} documentation.)\\
+%
+% \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.)\\
+%
+% \smallskip
+%
+% \noindent About how to get those packages, please see subsection~\ref{ss:Downloads}.

+% \section{The implementation}
+%
+% We start off by checking that we are loading into \LaTeXe\ and
+% announcing the name and version of this package.
+%
+% \begin{macrocode}
+%<*package>
+% \end{macrocode}
+%
+% \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}[1994/06/01]
+\ProvidesPackage{papermas}[2010/06/03 v1.0b
+ Computes paper mass of a printout (HMM)]%
+
+% \end{macrocode}
+%
+% A short description of the \textsf{papermas} package:
+%
+% \begin{macrocode}
+%% Allows to compute the number of sheets of paper
+%% needed to print a document as well as the
+%% mass of that printed version of the document,
+%% usefull e. g. when sending it by mail to determine the postage.
+%% Warning/Disclaimer: Mass of (printer's) ink has to be added
+%% (and that of envelope, address sticker, stamps,...)!
+%% So, this is only an estimation without guarantee -
+%% do not sue me, if you have got to pay excess postage!
+%% Further this package allows to compute
+%% "base to the power of exponent" inside TeX.
+
+% \end{macrocode}
+%
+% For the handling of the options we need the \textsf{kvoptions}
+% package of Heiko Oberdiek (see subsection~\ref{ss:Downloads}):
+%
+% \begin{macrocode}
+\RequirePackage{kvoptions}[2010/02/22]% v3.7
+% \end{macrocode}
+%
+% For the total number of pages we need the \textsf{pagesLTS}
+% package of myself (see subsection~\ref{ss:Downloads}):
+%
+% \begin{macrocode}
+\RequirePackage{pagesLTS}[2010/06/03]% v1.1b
+% \end{macrocode}
+%
+% A last information for the user(s):
+%
+% \begin{macrocode}
+%% papermas may work with earlier versions of those packages,
+%% but this was not tested. Please consider updating your packages
+%% to the most recent version (if they are not already the most
+%% recent version).
+
+% \end{macrocode}
+% See subsection~\ref{ss:Downloads} about how to get them.\\
+%
+% The options are introduced:
+%
+% \begin{macrocode}
+\SetupKeyvalOptions{family = papermas,prefix = papermas@}
+\DeclareStringOption[4]{format}[4]% paper foormat, ISO A...,
+ % default: (ISO A) 4
+\DeclareStringOption[80]{masss}[80]% specific mass of the paper,
+ % default: 80 (g/(m^2))
+\DeclareStringOption[2]{pagespersheet}[2]% number of pages per sheet,
+ % for duplex printing this is 2.
+
+\ProcessKeyvalOptions*
+
+% \end{macrocode}
+%
+% \begin{macro}{unit}
+% We want to use the |\unit| command from {\sl Scientific WorkPlace\/},
+% therefore we need to copy the definition:
+%
+% \begin{macrocode}
+%% Code from tcilatex.tex, Macros for Scientific Word and Scientific WorkPlace 5.5 <06 Oct 2005> %%
+%% Copyright (C) 2005 Mackichan Software, Inc. %%

+%% \def was changed to \gdef %%
+ \gdef\unit#1{\mathord{\thinspace\rm #1}}%
+%% End of code from tcilatex.tex %%
+
+% \end{macrocode}
+% \end{macro}
+%
+% \pagebreak
+%
+% Even if diverse commands are not defined yet, we do not want~a\\
+% \LaTeX \texttt{\ Error:~\ldots\ undefined}.

+% Introducing some new counters:

+% \begin{macrocode}
+\newcounter{papermas@rerun}
+\newcounter{papermas@base}
+\newcounter{papermas@exp}
+\newcounter{papermas@result}
+\newcounter{papermas@ini}
+\setcounter{papermas@ini}{1}
+
+% \end{macrocode}
+%
+% \begin{macro}{\papermas@powerof}
+% We need a command to compute
+% \textquotedblleft base to the power of exponent\textquotedblright\ $\left( base^{exponent}\right) $.\\
+% (Is this really not already implementet in \LaTeX?!)
+%
+% \begin{macrocode}
+\newcommand\papermas@powerof[2]{%
+ \setcounter{papermas@base}{#1}
+ \setcounter{papermas@exp}{#2}
+ \ifnum \value{papermas@ini}=1
+ \setcounter{papermas@result}{\value{papermas@base}}
+ \setcounter{papermas@ini}{0}
+ \ifnum \value{papermas@exp}=0%
+ \setcounter{papermas@result}{1}
+ \else
+ \addtocounter{papermas@exp}{-1}
+ \fi
+ \fi
+ \ifnum \value{papermas@exp}=0%
+ \setcounter{papermas@ini}{1}
+ \else
+ \multiply \value{papermas@result} \value{papermas@base}
+ \addtocounter{papermas@exp}{-1}
+ \papermas@powerof{#1}{\value{papermas@exp}}
+ \fi%
+ }
+
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\papermas@totmass}
+% This is the internal command, which computes the total paper mass
+% of the printed document.
+%
+% \begin{macrocode}
+\newcommand\papermas@totmass{%
+ \newcounter{papermasA}% paper mass for ISO A...
+ \setcounter{papermasA}{\papermas@format}% e. g. 4
+% \end{macrocode}
+%
+% We check whether |papermasA| has a resonable value:
+%
+% \begin{macrocode}
+ \ifnum \value{papermasA}<0%
+ \PackageError{papermas}{Option format has no valid value}%
+ {The format option of the papermas package\MessageBreak%
+ only takes whole, non-negative numbers (0, 1, 2, 3,...),\MessageBreak%
+ because this should be the paper format\MessageBreak%
+ ISO A 0, 1, 2, 3,...\MessageBreak%
+ Found instead: \papermas@format \MessageBreak%
+ }
+ \else%
+% \end{macrocode}
+%
+% |papermasA| has a resonable value. We introduce a new counter
+% |papermasmasss| and initialize it with the value given in option
+% |masss|, i.\,e. |\papermas@masss|.
+%
+% \begin{macrocode}
+ \newcounter{papermasmasss}% always 0
+ \setcounter{papermasmasss}{\papermas@masss}% default: 80
+% \end{macrocode}
+%
+% Counters are integers, but the amount of the mass of a single sheet
+% of paper in most cases is not an integer, therefore we multiply with
+% 100 to get two digits behind the decimal separator.\\
+% (Later we need to devide by 100 again, of course.)
+%
+% \begin{macrocode}
+ \multiply \value{papermasmasss} 100 % default: 8000
+% \end{macrocode}
+%
+% We check whether |papermasmasss| has a resonable value, i.\,e. $> 0$:
+%
+% \begin{macrocode}
+ \ifnum \value{papermasmasss}<1%
+ \PackageError{pagesLTS}{Option masss has no valid value}%
+ {The masss option of the papermas package\MessageBreak%
+ only takes positive numbers,\MessageBreak%
+ because this should be the mass per square meter\MessageBreak%
+ of a single sheet of your paper.\MessageBreak%
+ Found instead: \papermas@masss \MessageBreak%
+ }
+ \else
+% \end{macrocode}
+%
+% |masss| has a resonable value, and therefore also
+% |\papermas@masss| and |papermasmasss|.\\
+%
+% We check whether option |pagespersheet| has a resonable value, i.\,e. $\geq 1$:
+%
+% \begin{macrocode}
+ \newcounter{papermasPPS}% is 0
+ \setcounter{papermasPPS}{\papermas@pagespersheet}% default 2
+ \ifnum \value{papermasPPS} < 1%
+ \PackageError{papermas}{%
+ The number of pages per sheet must be positive.}{%
+ You cannot print less than one TeX page per sheet of paper.\MessageBreak%
+ The value found was \papermas@pagespersheet .\ \MessageBreak%
+ }
+ \else
+% \end{macrocode}
+%
+% |pagespersheet| has a resonable value, and therefore also\\
+% |\papermas@pagespersheet| and |papermasTmpA|.\\
+%
+% We introduce a new counter |papermas@sheets| for the number of
+% sheets printed and initialize it with the number of pages
+% as computed by package \textsf{pagesLTS},\newline
+% i.\,e. |pagesLTS.pagenr|.
+%
+% \begin{macrocode}
+ \newcounter{papermas@sheets}
+ \setcounter{papermas@sheets}{\arabic{pagesLTS.pagenr}}%
+% \end{macrocode}
+%
+% When more than one page is printed on one sheet of paper,
+% the number of sheets needed for printing is decreased:
+%
+% \begin{macrocode}
+ \divide \value{papermas@sheets} by \value{papermasPPS}%
+% \end{macrocode}
+%
+% |\divide| cuts off all digits behind the decimal separator,
+% but if there are digits $>0$, this means that there is
+% an additional, last sheet, which is only partially covered
+% with print (e.\,g. only one side of it for duplex printing
+% an odd number of pages). In that case, we have to add
+% one sheet of paper to the number of sheets needed.
+%
+% \begin{macrocode}
+ \newcounter{papermas@tmpn}
+ \setcounter{papermas@tmpn}{\arabic{papermas@sheets}}%
+ \multiply \value{papermas@tmpn} \value{papermasPPS}%
+ \ifnum \value{papermas@tmpn}=\value{pagesLTS.pagenr}
+ \relax
+ \else
+ \addtocounter{papermas@sheets}{1}%
+ \fi
+% \end{macrocode}
+%
+% Now we can multiply the specific mass of 100 sheets
+% with the number of sheets needed for printing:
+%
+% \begin{macrocode}
+ \multiply \value{papermasmasss} \value{papermas@sheets}
+ % default: 8000
+% \end{macrocode}
+%
+% The result is in $\unit{g}\unit{m}^{-2}$.\\
+% A sheet with format ISO A0 has a size of $1\unit{m}^{2}$,\\
+% a sheet with format ISO A1 has a size of $1\unit{m}^{2}\cdot 2^{-1}$,\\
+% a sheet with format ISO A2 has a size of $1\unit{m}^{2}\cdot 2^{-2}$,\\
+% \ldots
+% a sheet with format ISO A\textit{n} has a size of $1\unit{m}^{2}\cdot 2^{-n}$.\\
+% Therefore we compute $2^{\text{\textbackslash value\{papermasA\}}}$:
+%
+% \begin{macrocode}
+ \papermas@powerof{2}{\value{papermasA}}
+% \end{macrocode}
+%
+% The result is saved in |papermas@result|.\\
+% We divide the specific paper mass by |papermas@result|:
+%
+% \begin{macrocode}
+ \divide \value{papermasmasss} by \value{papermas@result}
+ % default: 16000 / 2^(\value{papermasA})
+% \end{macrocode}
+%
+% We need to get the division by 100 and the digits after the decimal separator right:
+%
+% \begin{macrocode}
+ % for the example 297 is used
+ \newcounter{papermas@tmpm}
+ \setcounter{papermas@tmpm}{\arabic{papermasmasss}}% m:297 n: o: p: q:
+ \setcounter{papermas@tmpn}{\arabic{papermasmasss}}% m:291 n:291 o: p: q:
+ \divide \value{papermas@tmpn} by 100% m:297 n:2 o: p: q:
+ \newcounter{papermas@tmpo}
+ \setcounter{papermas@tmpo}{\arabic{papermas@tmpn}}% m:291 n:2 o:2 p: q:
+ \multiply \value{papermas@tmpn} 10% m:297 n:20 o:2 p: q:
+ \divide \value{papermas@tmpm} by 10% m:29 n:20 o:2 p: q:
+ \newcounter{papermas@tmpp}
+ \setcounter{papermas@tmpp}{\arabic{papermas@tmpm}}
+ \addtocounter{papermas@tmpp}{-\arabic{papermas@tmpn}}%m:29 n:20 o:2 p:9 q:
+ % 29 - 20 = 9
+ \multiply \value{papermas@tmpm} 10% m:290 n:20 o:2 p:9 q:
+ \newcounter{papermas@tmpq}
+ \setcounter{papermas@tmpq}{\arabic{papermasmasss}}
+ \addtocounter{papermas@tmpq}{-\arabic{papermas@tmpm}}%m:290 n:20 o:2 p:9 q:7
+ % 297 - 290 = 7
+% \end{macrocode}
+%
+% Now rounding mathematically correct, i.\,e. $\geq 0.5$ becomes $1$
+% (and remember a possible amount carried forward!) and $< 0.5$ becomes %0%.
+%
+% \begin{macrocode}
+ \ifnum\value{papermas@tmpq}>4
+ \addtocounter{papermas@tmpp}{1}% m:290 n:20 o:2 p:10 q:7
+ \ifnum\value{papermas@tmpp}>9% m:290 n:20 o:2 p:10 q:7
+ \addtocounter{papermas@tmpo}{1}% m:290 n:20 o:3 p:10 q:7
+ \setcounter{papermas@tmpp}{0}% m:290 n:20 o:3 p:0 q:7
+ \fi
+ \fi
+% \end{macrocode}
+%
+% The result in the example above is $297/100=2.\,97\approx 3.\,0$.
+% We write this into |\papermastmpr| and the options' values into
+% temporary definitions, as well as the number of sheets:
+%
+% \begin{macrocode}
+ \edef\papermastmpr{\arabic{papermas@tmpo}.\arabic{papermas@tmpp}}%
+ \edef\papermastmpformat{\papermas@format}%
+ \edef\papermastmpmasss{\papermas@masss}%
+ \edef\papermastmppagespersheet{\papermas@pagespersheet}%
+ \edef\papermastmpt{\arabic{papermas@sheets}}%
+% \end{macrocode}
+%
+% We use the \textsf{pagesLTS} package, which already was used
+% to determine the total number of pages, to check for the
+% counter |papermassttl|. If it exists, nothing is done,
+% if it does not exist, it is declared as |\newcounter|
+% (and by default set to zero).
+%
+% \begin{macrocode}
+ \pagesLTS@ifcounter{papermassttl}
+% \end{macrocode}
+%
+% If the |papermassttl| counter value already has the value of
+% |papermasmasss|, everything is fine.
+%
+% \begin{macrocode}
+ \ifnum\value{papermassttl}=\value{papermasmasss}
+ \relax
+% \end{macrocode}
+%
+% Otherwise we need another run of \LaTeX.
+%
+% \begin{macrocode}
+ \else
+ \PackageWarningNoLine{papermas}{%
+ Number of pages may have changed.\MessageBreak%
+ Rerun to get it right.\MessageBreak%
+ }%
+ \fi
+% \end{macrocode}
+%
+% In any case, we set the counter |papermassttl| to the
+% current value of |papermasmasss|.
+%
+% \begin{macrocode}
+ \setcounter{papermassttl}{\arabic{papermasmasss}}
+% \end{macrocode}
+%
+% Because we want to write out into the \xfile{aux}-file,
+% we need the expanded value (as string) of |papermasmasss|:
+%
+% \begin{macrocode}
+ \edef\papermastmps{\arabic{papermasmasss}}%
+% \end{macrocode}
+%
+% If we are allowed to write into the \xfile{aux}-file,
+% we do it here. If we are not allowed to do it,
+% the \textsf{pagesLTS} package already gave an according
+% error message.
+%
+% \begin{macrocode}
+ \if@filesw%
+% \end{macrocode}
+%
+% When it is read from the \xfile{aux}-file and
+% when its content is processed, the counter |papermassttl|
+% might not have been defined yet. Therefore we again use the
+% |\pagesLTS@ifcounter| command of the \textsf{pagesLTS} package.
+%
+% \begin{macrocode}
+ \immediate\write\@auxout{\string
+ \pagesLTS@ifcounter{papermassttl}}%
+% \end{macrocode}
+%
+% We set the counter |papermassttl| to the value |\papermastmps|,\\
+% i.\,e. |\arabic{papermasmasss}|. In the next compilation run,
+% it will be checked,\\
+% whether |\value{papermassttl}=\value{papermasmasss}| (see above).\\
+% If this is the case, everything is OK, no changes happened,
+% and no rerun is necessary (at least not for \textsf{papermas}).
+%
+% \begin{macrocode}
+ \immediate\write\@auxout{\string
+ \setcounter{papermassttl}{\papermastmps}}%
+% \end{macrocode}
+%
+% What we do need, is to get the determined |\papermastmpr| to
+% the user.\\
+% Therefore
+%
+% \begin{enumerate}
+% \item we define |\papermasstotal| in the \xfile{aux}-file,
+% where the user can look it up
+%
+% \item we define |\papermasstotal|, so the user can e.\,g. write\\
+% \begin{verbatim}
+% This document consists of $\arabic{pagesLTS.pagenr}$~pages.
+% When printing $\papermaspagespersheet$~pages on one sheet of
+% paper, $\papermassheets$~sheets will be needed. For
+% ISO~A~\papermasformat\ paper of $\papermasmasss\unit{g}\unit{m}^{-2}$
+% specific mass, the printout will have a mass of about
+% $\papermasstotal\unit{g}$.
+% \end{verbatim}
+%
+% \begin{macrocode}
+ \immediate\write\@auxout{\string
+ \gdef\string\papermasstotal{\papermastmpr}}%
+ \immediate\write\@auxout{\string
+ \gdef\string\papermasformat{\papermastmpformat}}%
+ \immediate\write\@auxout{\string
+ \gdef\string\papermasmasss{\papermastmpmasss}}%
+ \immediate\write\@auxout{\string
+ \gdef\string\papermaspagespersheet{\papermastmppagespersheet}}%
+% \end{macrocode}
+%
+% \item we give at the screen the information about the |\papermasstotal|\\
+% (see |\AtVeryEnd| below)
+%
+% \item which will also appear in the \xfile{log}-file.
+%\end{enumerate}
+%
+% We want to give also |\papermastmpt = \arabic{papermas@sheets}| to the user,
+% i.\,e.~the number of sheets needed to print the document.
+% Therefore we follow the same procedure:
+% \begin{macrocode}
+ \immediate\write\@auxout{\string

+ \fi%
+ \fi%
+ \fi%

+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\AtBeginDocument}
+% \indent |\AtBeginDocument| it is checked whether some commands,

+% \DescribeMacro{papermas-example.tex}
+% The |papermas-example.tex| requires the same files as all
+% documents using the \textsf{papermas} package, especially:
+% \begin{description}
+% \item[-] package \textsf{papermas}, 2010/06/03, v1.0b,\\
+% \CTAN{macros/latex/contrib/muench/papermas/papermas.dtx}\\
+% (submitted, should become available at that location soon)\\
+% (Well, it is the example file for this package, and because you are reading the
+% documentation for the \textsf{papermas} package, it can be assumed that you already
+% have some version of it -- is it the current one?)
+% \end{description}
+%
+% \DescribeMacro{totpages}
+% As possible alternatives in section \ref{sec:Alternatives} there are listed
+% \begin{description}
+% \item[-] package \textsf{totpages}, 2005/09/19, v2.00,\\
+% \CTAN{macros/latex/contrib/totpages/totpages.dtx}
+% \end{description}
+%
+% \DescribeMacro{Oberdiek}
+% \DescribeMacro{holtxdoc}
+% \DescribeMacro{atveryend}
+% \DescribeMacro{kvoptions}
+% All packages of Heiko Oberdiek's bundle `oberdiek'
+% (especially \textsf{holtxdoc}, \textsf{atveryend}, \textsf{kvoptions})
+% are also available in a TDS compliant ZIP archive:\\
+% \CTAN{install/macros/latex/contrib/oberdiek.tds.zip}.\\
+% \textbf{Warning}: holtxdoc, 2010/04/24 v0.19, requires the packages
+% \begin{description}
+% \item[-] hypdoc, 2010/03/26, v1.9
+% \item[-] hyperref, 2010/03/30, v6.80u (latest: 2010/05/13, v6.81e)
+% \item[-] pdftexcmds, 2010/04/01, v0.9
+% \item[-] ltxcmds, 2010/03/09, v1.4 (latest: 2010/04/26, v1.7)
+% \item[-] hologo, 2010/04/24, v1.2
+% \item[-] array (latest: 2008/09/09, v2.4c)
+% \end{description}
+% (or more recent versions) and does neither work with
+% nor check for earlier versions!\\
+% (It is probably best to download\\
+% \CTAN{install/macros/latex/contrib/oberdiek.tds.zip}
+% and use this, because the packages in there should be both
+% recent and compatible.)\\
+%
+% \subsection{Package, unpacking TDS}
+%
+% \paragraph{Package.} This package should become available soon on \CTAN{}
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/muench/papermas/papermas.dtx}]\hspace*{0.1cm} \\
+% The source file.
+% \item[\CTAN{macros/latex/contrib/muench/papermas/papermas.ins}]\hspace*{0.1cm} \\
+% The installation file.
+% \item[\CTAN{macros/latex/contrib/muench/papermas/papermas.drv}]\hspace*{0.1cm} \\
+% The driver to generate the documentation.

+% The compiled example file, as it should look like.
+% \item[\CTAN{install/macros/latex/contrib/muench/papermas/papermas.tds.zip}]\hspace*{0.1cm} \\
+% Everything in TDS compliant, compiled format.
+% \end{description}
+%
+% For required other packages, see the preceding subsection.
+%
+% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
+% \docstrip\ archive. The files are extracted by running the
+% \xfile{.dtx} through \plainTeX:
+% \begin{quote}
+% \verb|tex papermas.dtx|
+% \end{quote}
+%
+% About generating the documentation see paragraph~\ref{GenDoc} below.\\
+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):
+% \begin{quote}
+% \def\t{^^A
+% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}
+% papermas.sty & tex/latex/muench/papermas.sty\\
+% papermas.pdf & doc/latex/muench/papermas.pdf\\

+% 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{papermas.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 the
+% 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 papermas.dtx
+%makeindex -s gind.ist papermas.idx
+%pdflatex papermas.dtx
+%makeindex -s gind.ist papermas.idx
+%pdflatex papermas.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \subsection{Compiling the example}
+%
+% The example file, \textsf{papermas-example.tex}, can be compiled via\\
+% \indent |latex papermas-example.tex|\\
+% or (recommended)\\
+% \indent |pdflatex papermas-example.tex|\\
+% but will need probably three compiler runs to get everything right.
+%
+% \section{Things suggested to be done\label{sec:todo}}
+%
+% \begin{itemize}
+% \item Include a correct checksum for \textsf{papermas}.
+% \item Insert the final references where to get the files at \CTAN{}.
+% \end{itemize}
+%
+% \section{Acknowledgements}
+%
+% I (H.-Martin M\"{u}nch) would like to thank Heiko Oberdiek
+% (heiko dot oberdiek at googlemail dot com) for providing
+% a~lot~(!) of usefull packages (from which I also got everything I
+% know about creating a file in \xfile{dtx} format, ok, say it: copying),
+% and the \Newsgroup{comp.text.tex} and \Newsgroup{de.comp.text.tex}
+% newsgroups for their help in all things \TeX.
