+% Configuration file for the errata listing of 
+%
+%  Der LaTeX-Begleiter 2 Auflage
+%
+%
+% \erratastartdate 
+%
+% Specifies the date from which on errata entries should be listed.
+%
+% The format is YYYY/MM/DD.
+%
+% The default below ensures that all entries for a particular
+% printing are typeset.
+%
+
+\renewcommand\erratastartdate{2005/09/01}
+
+
+%
+% \myprinting
+%
+% Specifies which (revised) printing you own. For example, if you
+%    have the second printing set this to 2 so that errors already
+%    corrected in that printing will not appear in your errata
+%    listing.
+%
+% The default below ensures that all entries relevant to the second
+%    printing are typeset. 
+%    
+%
+
+\renewcommand\myprinting{2}
+
+%
+% \norevisionnumbers
+%
+% Specifies that all page numbers in the errata are shown in the same
+%    format (bold face) irregardless of whether or not they are fixed
+%    in some revision. The default is to print corrected errors in
+%    italic and add the revision number as a superscript.
+
+%
+% \showallerrors
+%
+% With this command you tell the program that all errata entries are
+%    supposed to be generated. This makes \myprinting and
+%    \erratastartdate basically obsolete so this isn't turned on by
+%    default.

+%
+%
+% \erratastartdate 
+%
+% Specifies the date from which on errata entries should be listed.
+%
+% The format is YYYY/MM/DD.
+%
+% The default below ensures that all entries for a particular
+% printing are typeset.
+%
+
+\renewcommand\erratastartdate{2007/06/30}
+
+
+%
+% \myprinting
+%
+% Specifies which (revised) printing you own. For example, if you
+%    have the second printing set this to 2 so that errors already
+%    corrected in that printing will not appear in your errata
+%    listing.
+%
+% The default below ensures that all entries relevant to the x-th
+%    printing are typeset. 
+%    
+%
+
+\renewcommand\myprinting{2}
+
+%
+% \norevisionnumbers
+%
+% Specifies that all page numbers in the errata are shown in the same
+%    format (bold face) irregardless of whether or not they are fixed
+%    in some revision. The default is to print corrected errors in
+%    italic and add the revision number as a superscript.
+
+%
+% \showallerrors
+%
+% With this command you tell the program that all errata entries are
+%    supposed to be generated. This makes \myprinting and
+%    \erratastartdate basically obsolete so this isn't turned on by

+number of bugs during that period (in case of a draw a random choice
+will be made between all those with the largest number of findings).
+A person can receive at most one prize, ever; errors found by any of

+Each prize is a free choice of any single computing book found on the
+AW Professional web site \texttt{http://www.awprofessional.com} (that
+is, no boxed sets or multiple volume offers).
+
+
+As usual, the authors and publisher reserve the right to make various

+multiple errors.  --- 
+Good luck!

+   Due to the printing process there may be small alignment problems

+\seriouserroronpage{683}{exa. 10-1-22}{FMi}{2007/08/26}{2}
+The example unfortunately highlights a bug in the current texmate package: a
+linebreak (in contrast to a space) is not recognized as a move separator
+resulting in all moves getting scrambled in the output, e.g., you see
+\texttt{dxe5 Bxf3 Qxf5} put together under move 4.

+\seriouserroronpage{741}{Ex 11-3-5}{MiV}{2008/05/22}{2} 
+Usage of
+\verb=\cellcolor= might introduce extra space in the output (as one can see in
+the example).
+
+This can be argued as being a bug in the \texttt{colortbl} package. Given that the
+basic \verb=\color= command ignores spaces after it, \verb=\cellcolor= should
+behave similarly.
+
+\seriouserroronpage{744}{line after Ex 11-3-9}{MiV}{2008/05/22}{2}

+\erroronpage{760}{fig. 11.1}{MiV}{2008/05/22}{2}
+
+why differs section names (``Introduction to encoding'' vs. ``Introduction''

+
+Frank: because the author of this section used a real live example where he had

+some reason (should be mentioned in the source though).
+
+\erroronpage{774}{2nd snytax box}{hv}{2009/05/8}{2}

+
+This document is under construction \ldots
+
+
+\section{Primitive requirements}
+
+Since the finalisation of \eTeX{} in 1999, a number of additional `utility'
+primitives have been added to \pdfTeX{}. Several of these are broadly useful
+and have been requirements for \pkg{expl3} for some time, most notably
+\cs{pdfstrcmp}. Over time, a common set of these `post-\eTeX{}' primitives have
+been incorporated into \XeTeX{} and (u)p-\TeX{}; they were available in
+\LuaTeX{} already.
+
+A number of the additional primitives are needed to support new or improved
+functionality in \LaTeX{}. This is seen for example in improved UTF-8 handling,
+which uses \cs{ifincsname}. The following primitive functionality (which in
+\LuaTeX{} may be achieved using Lua code) will therefore be \emph{required} by
+the \LaTeX{} kernel after [INSERT DATE HERE]:
+\begin{itemize}
+  \item \cs{expanded}
+  \item \cs{ifincsname}
+  \item \cs{ifpdfprimitive}
+  \item \cs{pdfcreationdate}
+  \item \cs{pdfelapsedtime}
+  \item \cs{pdffiledump}
+  \item \cs{pdffilemoddate}
+  \item \cs{pdffilesize}
+  \item \cs{pdflastxpos}
+  \item \cs{pdflastypos}
+  \item \cs{pdfmdfivesum}
+  \item \cs{pdfnormaldeviate}
+  \item \cs{pdfpageheight}
+  \item \cs{pdfpagewidth}
+  \item \cs{pdfprimitive}
+  \item \cs{pdfrandomseed}
+  \item \cs{pdfresettimer}
+  \item \cs{pdfsavepos}
+  \item \cs{pdfsetrandomseed}
+  \item \cs{pdfshellescape}
+  \item \cs{pdfstrcmp}
+  \item \cs{pdfuniformdeviate}
+\end{itemize}
+For ease of reference, these primitives will be referred to as the
+`\pdfTeX{} utilities'.
+
+Engines which are fully Unicode-capable must all provide the following
+primitives
+\begin{itemize}
+  \item \cs{Uchar}
+  \item \cs{Ucharcat}
+  \item \cs{Umathcode}
+\end{itemize}
+In particular, note that \cs{Umathcode} is used as a marker primitive for
+this capability.
+
+\section{Experiences with the \LaTeX\texttt{-dev} formats}
+
+\emph{write}
+
+In TeXLive 2020 the Lua\LaTeX{} format will use the new LuaHB\TeX{} engine, which is Lua\TeX{} with an embedded HarfBuzz library.
+HarfBuzz can be used by setting a suitable renderer in the font declaration. An interface for that is provided by \pkg{fontspec}.
+This additional font renderer will greatly improve the shaping of various scripts, which are currently handled correctly only by \XeTeX{}.
+To simplify the testing of the new engine, binaries have been added to MiKTeX and TeXLive 2019 and both have changed the Lua\LaTeX-dev format to use it.
+
+\section{Improved load-times for \pkg{expl3}}
+
+The \LaTeX3 programming layer, \pkg{expl3}, has over the past decade moved from
+being largely experimental to broadly stable. It is now used in a significant
+number of third-party packages, most notably \pkg{xparse} for defining
+interfaces in cases where no \pkg{expl3} code is \enquote{visible}. Most
+\LaTeX{} documents compiled using \XeTeX{} or \LuaTeX{} load \pkg{fontspec},
+which is written using \pkg{expl3}.
+
+The \pkg{expl3} layer contains a non-trivial number of macros, and when used
+with the \XeTeX{} and \LuaTeX{} engines, it loads a large body of Unicode data.
+This means that even on a fast computer, there is a relatively large load time for
+using \pkg{expl3}.
+
+For this release, the team have made adjustments in the \LaTeXe{} kernel to
+pre-load a significant portion of \pkg{expl3} as the format is built. This is
+transparent at the user level, other than the significant decrease in document
+processing time: there will be no \enquote{pause} for loading Unicode data
+files. Loading of \pkg{expl3} in documents and packages can be done as usual;
+eventually, it will be possible to omit
+\begin{verbatim}
+\RequirePackage{expl3}
+\end{verbatim}
+entirely, but to support older formats, this is still recommended at present.

+\noindent These are all the errors and omissions to the manual,
+\LaTeX: {\em A Document Preparation System}, second edition, published
+by Addison-Wesley, reported as of \moddate.  Positions in the book are
+indicated by page and line number, where the top line of a page is
+number 1 and the bottom line is number $-1$.  A running head and a
+page number are not considered to be lines, but all other lines are.
+Please report any additional errors to The \LaTeX\ Project at

+ \reportedby{Rosemary Bailey}{29 Aug 1994}
+
+\erratum{page 28, first paragraph} 
+Not an error, but it would be

+ ``(If a declaration has arguments, they become additional
+arguments of the corresponding environment's \verb|\begin| command.)''

+\erratum{page 101}
+This is not an error, but some readers will find it helpful if, in the

+\verb|\gnat| were replaced by \verb|\parskip|.  
+ \reportedby{Ellen Gilkerson}{9 Aug 1994}
+
+\erratum{page 108, lines 7 and 10}
+This is not an error, but it might be easier to understand
+the example if \verb|\len| were replaced by something like \verb|\saved|.

+% Specifies which (revised) printing you own. For example, if you

+% Specifies that all page numbers in the errata are shown in the same

+For this reason Addison-Wesley and the authors offer a prize (for 6 
+periods) to the eligible person who finds the largest
+number of bugs during that period (in case of a draw a random choice
+will be made between all those with the largest number of findings).
+A person can receive at most one prize, ever; errors found by any of
+the authors do not count.
+
+Each prize is a free choice of any single computing book found on the
+AW Professional web site \texttt{http://www.awprofessional.com} (that
+is, no boxed sets or multiple volume offers).
+
+
+As usual, the authors and publisher reserve the right to make various
+decisions such as whether a reported feature is an error for
+competitive purposes or whether similar features count as a single or
+multiple errors.  --- 
+Good luck!

+Poor Maxwell's equations! No doubt there are mathematical
+ physicists or physical mathematicians that write Maxwell's equations that way.
+ This is a good example for showing some capabilities of the
+ \textsf{amsmath} package and its possible extensions by means of the
+ \comando{\newenvironment} command, but it is an example where all possible ISO
+ rules are violated! Physical equations deal with quantities, not with
+ mathematical variables; and quantities have dimensions; as such they have to
+ comply with the rules established by the Sisth\`{e}me International (SI) and the
+ various obsolete ``cgm'' systems are officially deprecated; the partial
+ derivative sign $\partial$ has exactly that meaning and it cannot substitute
+ the ``nabla'' $\nabla$ sign;  finally the $j$ symbol probably indicates the
+ current density, but in an equation that does not comply with the ISO rules it
+ might indicate the imaginary unit (which, on the opposite, is prescribed to be
+ typeset in roman or upright shape as well as $\pi$); treating with vectorial
+ quantities these should be well marked either with a vector math accent or
+ must be set in bold italic; with variables depending from four quantities the
+ apex for indicating the derivative is not univocal for specifying the quantity
+ with respect to which the derivative is taken. I repeat: the example is good
+ for describing the math extension capabilities but it could induce the casual
+ reader to believe that this is the correct form for writing down the Maxwell's
+ equations; unfortunately it is not.

+Additional remarks not for inclusion in the book: For \TeX{}, \LaTeX{}
+in languages of India, 
+there are several nice packages.  An overview can be found in the
+following {\sc TUGboat} Articles;
+
+\begin{enumerate}

+\end{enumerate}
+
+In addition to these articles, TUGIndia has uploaded two
+\LaTeXe{} packages (i) Malayalam for \LaTeXe{}, and (ii) Kannada
+\LaTeX{}, both available from www.sarovar.org.
+
+A remark on {\sf devnag} package:-- Originally developed by Frans
+Velthuis in 1991, it was upgraded for use with \LaTeXe{} (made
+NFSS-complaint), and maintained by a team consisting of Dominik
+Wujastyk, John Smith, Anshuman Pandey, Fran\c{c}ois Patte, and
+Zden\v{e}k Wagner. Very recently, the project has
+been handed over to TUGIndia, for further development,
+and as of May 2004, it has moved from sourceforge.net to

+\renewcommand\erratastartdate{1999/05/01}
+
+%
+% \myprinting
+%
+%    Specifies which (revised) printing you
+%    own. For example, if you have the second
+%    printing set this to 2 so that errors 
+%    already corrected in that printing will not
+%    appear in your errata listing.
+%
+%    The default below ensures that all

+%
+% \norevisionnumbers
+%
+% Specifies that all page numbers in the errata are shown in the same
+%    format (bold face) irregardless of whether or not they are fixed
+%    in some revision. The default is to print corrected errors in
+%    italic and add the revision number as a superscript. 
+%
+%
+% \showallerrors
+%
+% With this command you tell the program that all errata entries are
