+
+
+1 INTRODUCTION
+==============
+
+This package allows to override existing labels,
+especially automatically generated ones.
+
+Note: The main code of the undolabl package was invented
+by Ulrich Diez (eu_angelion at web dot de) in 2008 and
+published on the internet. While Ulrich Diez neither
+wanted to create a package himself nor have one published
+under his name, he granted the publication of his code.
+Therefore: Thanks!
+I (H.-Martin Münch) submitted this package to CTAN
+(after some updates of the documentation, mainly layout,
+ typos and such things.)
+
+
+2 DOWNLOAD
+==========
+
+`undolabl' is available on CTAN:
+  CTAN:macros/latex/contrib/muench/undolabl/
+
+Also a ZIP file is provided that contains the files, already
+sorted in a TDS tree:
+  CTAN:install/macros/latex/contrib/muench/undolabl.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/muench/pagesLTS/
+corresponds to
+  CTAN:macros/latex/contrib/muench/pagesLTS/
+
+
+3 INSTALLATION
+==============
+
+Installation with ZIP file in TDS format
+----------------------------------------
+The ZIP file `undolabl.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.../undolabl.tds.zip
+Do not forget to refresh the file name database of this
+TDS tree.
+Example:
+  texhash /...somewhere.../texmf
+
+Manual installation
+-------------------
+a) Download the undolabl files from CTAN or the TUG server.
+   If necessary, unpack them.
+b) If directory `beta' exists, replace the files by the
+   counterparts in this directory, if you want to use the
+   latest versions.
+c) Generate the package and driver files:
+     tex undolabl.ins
+d) Install the files `*.sty', and `*.cfg' in your TDS tree:
+     cp *.sty *.cfg TDS:tex/latex/muench/undolabl/
+   Replace `TDS:' by the prefix of your TDS tree
+   (texmf directory).
+e) Copy the documentation files to
+   "TDS:doc/latex/muench/undolabl/":
+   README, undolabl.pdf, undolabl-example.tex,
+   undolabl-example.pdf.
+f) Update the databases if necessary, e. g. for teTeX:
+     mktexlsr .../texmf
+
+
+4 ADDITIONAL PACKAGES
+=====================
+
+undolabl itself does not load other packages,
+but working with labels usually means using
+* hyperref.sty:
+    CTAN:macros/latex/contrib/hyperref/
+which again loads other packages
+(see the result of the \listfiles command in the log-file
+ of the example).
+
+
+5 PACKAGE COMPATIBILITY
+=======================
+
+There are no known incompatibilities (yet).
+
+6 AUTHOR/MAINTAINER
+=====================
+
+* Author of the original main code: Ulrich Dietz (Thanks!)
+* Author of the recent package and 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!
+
+Bug address

+% \section{Introduction\label{sec:Introduction}}
+%
+% The package's name \texttt{undolabl} is an eight-letter
+% abbreviation for the phrases ``undo'' and ``label''.\\
+%
+%  This package allows to override existing labels,
+%  especially automatically generated ones.\\
+%
+% When an instance of the |\label|-macro occurs in the document\linebreak
+% (e.\,g. |\label{foo}|), then a delayed |\write| (a write which is
+% performed at shipout-time when the page-number is determined) to
+% the |.aux| file is issued and you find in the |.aux| file something
+% like:
+% \begin{verbatim}
+%  \newlabel{foo}{{<page-no>}{<sectional no>}{<probably something else>}}
+% \end{verbatim}
+% During the beginning of the next \LaTeX -run, the |.aux| file will be
+% read and
+% \begin{verbatim}
+%  \newlabel{foo}{{<page-no>}{<sectional no>}{<probably something else>}}
+% \end{verbatim}
+% is expanded to
+% \begin{verbatim}
+%  \@newl@bel r{foo}{{<page-no>}{<sectional no>}{<probably something else>}}
+% \end{verbatim}
+% which in turn gets expanded to something like (pseudo code):
+% \begin{verbatim}
+% IF (macro \r@foo is already defined)
+% THEN
+%   - Issue an error-message,
+%   - Make sure that the multiply-defined-labels-warning occurs
+%     in the log-file
+% ELSE
+%  \def\r@foo{{<page-no>}{<sectional no>}{<probably something else>}}
+% ENDIF
+% \end{verbatim}%
+%
+% Referencing works as follows:\\
+% |\ref{foo}| |->|
+% \begin{description}
+%   \item[-] expand |\r@foo|: |{<page-no>}{<sectional no>}{<probably something else>}|
+%
+%   \item[-] grab the second from the resulting arguments: |<sectional no>|
+% \end{description}
+% |\pageref{foo}| |->|
+% \begin{description}
+%   \item[-] expand |\r@foo|: |{<page-no>}{<sectional no>}{<probably something else>}|
+%
+%   \item[-] grab the first from the resulting arguments: |<page-no>|
+% \end{description}
+% Back to the |\label|-mechanism:
+% \begin{description}
+%   \item[-] At the beginning of the \LaTeX -run, all the |\r@<label>|-macros
+%     get defined from reading the |.aux| file. The |\r@<label>|-macros
+%     get used by the referencing-macros (|\ref|, |\pageref|...) during
+%     the \LaTeX-run.
+%
+%   \item[-] During the \LaTeX -run, the |.aux| file gets rewritten.
+%
+%   \item[-] At the end of the \LaTeX -run, the |.aux| file (which was
+%     rewritten/newly created during the \LaTeX -run) is read in order
+%     to detect whether references have changed during the current
+%     \LaTeX -run.
+% \end{description}
+% But this time |\@newl@bel| is redefined (|\let equal to \@testdef|)
+% and thus this time\\
+% \begin{verbatim}
+% \@newl@bel r{foo}{{<page-no>}{<sectional no>}{<probably something else>}}
+% \end{verbatim}
+% expands to something like (pseudo code):
+% \begin{verbatim}
+%   Compare the (newly written) third argument (that is:
+%   {{<page-no>}{<sectional no>}{<probably something else>}} )
+%   to the (current/former) definition of \r@foo.
+%   If the two are different, then some page- or section-number
+%   related to referencing has changed from the last to the current
+%   LaTeX-run, thus in this case issue a message in the log-file:
+%   "References may have changed. Rerun LaTeX in order to get
+%   cross-references right".
+% \end{verbatim}
+% So what do you need to do in order to override a label:
+% \begin{description}
+%   \item[-] First you need to write to the |.aux| file to silently undefine
+%     the associated |\r@<label>|-macro if it is already defined.
+%     That's why |\overridelabel| writes in terms of |\protected@write|
+%     to the |.aux| file:
+%     \begin{verbatim}
+%       \undonewlabel{<label>}{<code-line-number>}
+%     \end{verbatim}
+%     |\undonewlabel| "undefines" the |\r@<label>|-macro.
+%     (How this works will be explained below.)
+%
+%   \item[-] Then |\overridelabel| can call |\label{<label>}| again
+%     and thus produce another |\newlabel{<label>}|-entry to the
+%     |.aux| file.
+% \end{description}
+% In the |.aux| file all this results in a sequence like:
+% \begin{verbatim}
+%   % from the former \label-call:
+%   \newlabel{<label>}{..}
+%   |->| \r@<label>-macro gets produced.
+%   % from the \overrridelabel-call:
+%   % - call to \undonewlabel within \overrridelabel:
+%   \undonewlabel{<label>}{<code-line-number>}
+%   |->| \r@<label>-macro gets destroyed.
+%   % - call to \label within \overrridelabel:
+%   \newlabel{<label>}{..}
+%   |->| a new \r@<label>-macro and no multiply-label-defined warning
+%   gets produced.
+% \end{verbatim}
+%
+% There is another issue left:
+% \begin{description}
+%   \item[-] It was said that |.aux| file is read at the beginning and at the
+%     end of the \LaTeX-run for detecting whether references have changed.
+%
+%   \item[-] When overriding a |<label>|, there will be several
+%     |\newlabel{<label>}|-calls associated to the same label-name in
+%     the |.aux| file.
+%
+%   \item[-] At the beginning of the \LaTeX -run only the last one counts for
+%     defining the associated |\r@<label>|-macro.
+%
+%   \item[-] But at the end, when the new |.aux| file is read, they all count
+%     and thus with all these entries but the last one, the
+%     above-mentioned |\@testdef|-comparison will yield difference and thus
+%     in any case cause a warning-message about references having
+%     changed although that might not be a correct statement.
+% \end{description}
+%
+% Ulrich Diez decided to catch this up by letting |\undonewlabel| "count"
+% within the macro |\s@<label>| how many times the label was
+% overridden. That means: Whenever |\r@<label>| is overridden, the
+% definition of |\s@<label>| gets a character "i" attached.
+%
+% The |\@testdef|-comparison-mechanism gets enhanced via replacing\footnote{%
+% "replacing" works as follows: When |.aux| file is read at the%
+% beginning of the \LaTeX -run, |\@newl@bel| is \underline{not} let equal to%
+% |\@testdef|. When |.aux| file is read at the end of the \LaTeX -run,%
+% |\@newl@bel| \underline{is} let equal to |\@testdef|. Thus it is sufficient%
+% to write into the beginning of the |.aux| file a direction which%
+% leads to letting |\@newl@bel| equal to%
+% \nolinebreak{\textbackslash |my@testdef|} in case its%
+% definition equals |\@testdef|. That direction is called%
+% \nolinebreak{"\textbackslash |reset@newl@bel|".}%
+% Also, when the |.aux| file is read at the end of the \LaTeX -run,%
+% \nolinebreak{\textbackslash |undonwelabel|}-entries therein should%
+% do nothing, thus%
+% \nolinebreak{\textbackslash |undonewlabel|} is let equal%
+% to |\@gobbletwo|.} it by |\undolabl@testdef|:
+% Before actually executing |\@testdef|, check whether\linebreak
+% |\s@<label>| is defined and empty. If undefined or empty,
+% perform |\@testdef|. If not empty, remove an "i" from its definition-text.
+% This way it is ensured that only the last one of several
+% |\newlabel{<label>}|-entries is used for the |\@testdef|-comparison.

+% \section{Usage}
+%
+% Load the package placing
+% \begin{quote}
+%   |\usepackage{undolabl}|
+% \end{quote}
+% \noindent in the preamble of your \LaTeXe\ source file.\\
+%
+% When an existing label shall be replaced by a new one, say\\
+% |\overridelabel{<label name>}|\\
+% (where |<label name>| is the name of the label to be replaced
+% by the new one), instead of just |\label{<label name>}|,
+% which would produce a\\
+% |LaTeX Warning: Label `<label name>' multiply defined.|

+% \DescribeMacro{\overridelabel}
+% In order to override a label, first you need to write to the
+% |.aux| file to silently undefine the associated |\r@<label>|-macro
+% if it is already defined. That's why |\overridelabel| writes in
+% terms of |\protected@write| to the |.aux| file:
+% |\undonewlabel{<label>}{<code-line-number>}|,
+% "undefining" the |\r@<label>|-macro.

+\newcommand\overridelabel[1]{%
+  \@bsphack
+  \protected@write\@auxout{}{\string\undonewlabel{#1}{\on@line}}%
+%    \end{macrocode}
+%
+% Then |\overridelabel| can call |\label{<label>}| again
+% and thus produce another |\newlabel{<label>}|-entry to the
+% |.aux| file.

+% \DescribeMacro{undolabl.dtx}
+% For unpacking the |undolabl.dtx| file and constructing the documentation it is required:
+% \begin{description}
+% \item[-] \TeX Format \LaTeXe, 1994/06/01, v2$\varepsilon $: \CTAN{}
+%
+% \item[-] document class \textsf{ltxdoc}, 2007/11/11, v2.0u,\\

+% \item[-] \TeX Format \LaTeXe, 1994/06/01, v2$\varepsilon $, \CTAN{}
+% \end{description}
+%
+% \DescribeMacro{undolabl-example.tex}
+% The |undolabl-example.tex| requires the same files as all
+% documents using the \textsf{undolabl} package, and additionally:
+% \begin{description}
+% \item[-] class \textsf{article}, 2007/10/19, v1.4h, from \textsf{classes.dtx}:\\
+%           \CTAN{macros/latex/base/classes.dtx}

+%            \CTAN{macros/latex/contrib/hyperref/},\\
+%            if |nameref| shall be used\\
+%            (and when the references shall be hyperlinked, of course)
+%
+% \item[-] package \textsf{undolabl}, 2010/06/03, v1.0b,\\
+%           \CTAN{macros/latex/contrib/muench/undolabl/undolabl.dtx}\\
+%           (submitted, should become available at that location soon)\\
+%   (Well, it is the example file for this package, and because you are reading the

+% \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 \xext{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{undolabl.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 \xext{dtx} or the \xext{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 undolabl.dtx
+%makeindex -s gind.ist undolabl.idx
+%pdflatex undolabl.dtx
+%makeindex -s gind.ist undolabl.idx
+%pdflatex undolabl.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \noindent and with \pdfLaTeX:
+% \begin{quote}
+%\begin{verbatim}
+%pdflatex undolabl.dtx
+%makeindex -s gind.ist undolabl.idx
+%pdflatex undolabl.dtx
+%makeindex -s gind.ist undolabl.idx
+%pdflatex undolabl.dtx
+%\end{verbatim}
+% \end{quote}

+% \section{Acknowledgements}
+%
+% I (H.-Martin M\"{u}nch) would like to thank
+% \textbf{Ulrich Diez (\texttt{eu\_angelion@web.de})}
+% for writing the main code of this package as well as for the
+% permission to publish it on \CTAN{}. I also thank
+% those anonymouse people who had published it on the internet.
+% Further I would like to thank Heiko Oberdiek
+% (\texttt{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.
