1 INTRODUCTION
==============

This package allows to override existing labels,
especially automatically generated ones.

Note: The main code of this package was invented by
Ulrich Diez (eu_angelion@web.de) and first published in the
comp.text.tex newsgroup at Sun, 20 Apr 2008 16:39:26 +0200, with subject:
Re: How to undefine/overwrite a label? (see e.g.
http://groups.google.de/group/comp.text.tex/msg/5ba8d4722e5cd326.
While Ulrich Diez neither wanted to create a package himself yet
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/undolabl/

Also a ZIP file is provided that contains the files, already
sorted in a TDS tree:
  CTAN:install/macros/latex/contrib/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/undolabl/
corresponds to
  CTAN:macros/latex/contrib/undolabl/


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!
