-\maketitle
-
-This package provides some miscellaneous tools for mathematical 
-accents, with the following goals in mind:
-\begin{itemize}
-\item Creating faked accents from non-accent symbols, like
-$\accentset{\star}{s}$.
-\item Grouping them, perhaps including actual accents, like 
-$\hat{\accentset{\star}{\hat h}}$. That
-has the side effect that multiple actual accents can be built
-as well.
-\item Putting them below the main symbol instead of above.
-\end{itemize}
-
-That is done so that the faked accents behave in quite similar fashion 
-to actual accents do; i.e., the skew of the letter is taken into 
-account (compare $\accentset{\ast}{d}$ with 
-$\accentset{\ast}{h}$) and the sub and superscripts attached to 
-it aren't misplaced (look carefully at $\accentset{\star}{f}_1^1$).
-
-Release 1.1 included a few new features, some of them following 
-suggestions by Donald Arseneau.  In particular, the |\underaccent| 
-command has been fully reimplemented for the slant to be taken into 
-account and the ``accent'' to be placed below the symbol can be 
-anyone, not only real accents. This release just makes it compatible
-with \textsf{amsmath} 2 with a quick fix.
-
-\begin{decl}
-|\DeclareMathAccent|
-\end{decl}
-
-This \LaTeXe{} command is reimplemented so that newly defined accents 
-will incorporate the features of this package.  The standard accents 
-are automatically redefined, including |\mathring| if you are using 
-one of the latest \LaTeX{} releases.  However, both |\widetilde| and
-|\widehat| remains untouched.  If you are using a non standard 
-math encoding, the accents following the standard encoding names are 
-rightly redefined, but new accents are not converted because 
-\textsf{accents} is not aware of its existence.
-
-See |fntguide.tex| in the \LaTeX{} standard distribution for a discussion on
- |\DeclareMathAccent|.
-
-\begin{decl}
-|\ring{<symbol>}|
-\end{decl}
-
-The accent in $\ring{x}$, which was available in this package (and
-in fact in many others) before
-the |\mathring| command was added to the \LaTeX{} kernel.
-
-\begin{decl}
-|\accentset{<accent>}{<symbol>}|
-\end{decl}
-
-Builds a faked accent, as for instance
-\begin{sample}
-|\accentset{\star}{d}|    \> $\accentset{\star}{d}$\\
-|\accentset{\diamond}{h}| \> $\accentset{\diamond}{h}$\\
-|\tilde{\accentset{\circ}{\phi}}| \>
-    $\tilde{\accentset{\circ}{\phi}}$
-\end{sample}
-The |<accent>| is always in |\scriptscriptmode|; hence, using
-|\accentset| in scripts won't give the desired  result. Of course,
-if you use some faked accent many times, you can define:
-\begin{verbatim}
-\newcommand\starred[1]{\accentset{\star}{#1}}
-\end{verbatim}
-and |\starred| will become an accent, like |\hat|, |\tilde|, etc.
-
-\begin{decl}
-|\dddot  \ddddot|
-\end{decl}
-
-Two prefabricated faked accents: $\dddot{f}$ and $\ddddot{f}$.
-
-\begin{decl}
-|\underaccent{<accent>}{<symbol>}|
-\end{decl}
-
-This command puts the |<accent>| under the |<symbol>|. Both real
-and faked accents are allowed. For instance,
-\begin{sample}
-|\underaccent{\hat}{x}|      \> $\underaccent{\hat}{x}$\\
-|\underaccent{\bar}{\gamma}| \> $\underaccent{\bar}{\gamma}$\\
-|\underaccent{\triangleright}{q}|  \>
-   $\underaccent{\triangleright}{q}$\\
-|\underaccent{\tilde}{\mathcal{A}}| \>
-    $\underaccent{\tilde}{\mathcal{A}}$
-\end{sample}
-
-Many people likes using the wider version of the tilde accent as 
-printed by the |\widetilde| command, i.e., $\widetilde{A}$ instead of 
-$\tilde{A}$.  I find that aesthetically questionable, but anyway it
-can be used under the symbol as well. Since |\widetilde| remains
-untouched, you should define:
-\begin{verbatim}
-\DeclareMathAccent{\wtilde}{\mathord}{largesymbols}{"65}
-\end{verbatim}
-and write |\underaccent{\wtilde}{V}|, say (giving 
-$\underaccent{\wtilde}{V}$). You may build an accent with
-|\sim|, too. (The value for a wide hat is |"62|)
-
-Sadly, \TeX{} lacks of a mechanism to place underaccents similar to 
-that used in accents.  Letters have a large variety of shapes and 
-finding an automatic adjusting is practically impossible.  Compare for 
-instance the following letters:
-\begingroup
-\def\\{\underaccent{\bar}}%
-$\\V$, $\\Q$, $\\p$, $\\q$, $\\f$,
-$\\\beta$, $\\\gamma$, $\\{\mathcal{F}}$, $\\{\mathcal{A}}$
-\endgroup
-and you wil understand the difficulties.
-
-\begin{decl}
-|\undertilde{<symbols>}|
-\end{decl}
-
-This is the ``under'' version of |\widetilde| and like the latter is intended for constructions
-involving several symbols. For instance:
-\begin{sample}
-|\undertilde{CV}| \> $\undertilde{CV}$
-\end{sample}
-Note that in this case no correction is made in the placement of the tilde.
-
-\begin{decl}
-|nonscript single|
-\end{decl}
-
-These package options are intended mainly for speeding up the 
-typesetting of document.  The algorithm used here is recursive and 
-very slow; although in fast processors that is not felt, in slow 
-system that could be very annoying.
-
-\begin{description}
-\item[single] If you are interested only in |\accentset|.
- Accents are not reimplemented.
-\item[nonscript] If you intend to use multiple accents in
- text and display modes only.
-\end{description}
-
-Macros are speeded up dramatically with both options; if your system is slow,
-I commend using them in drafts and removing them for the final print.
-
-Finally, some remarks:
-\begin{itemize}
-\item The package does not provides alternative accents for fonts
-  lacking them. If you want an accented  |\mathcal| letter you had to
-  write |\hat{\hat{\mathcal{A}}}| ($\hat{\hat{\mathcal{A}}}$).
-\item |\mathbf{\hat{\hat h}}| gets the bold accent;
- |\hat{\hat{\mathbf{h}}}| not.
-\item The symbol in |\accentset| must be a single symbol.
-\item If you use \textsf{accents} with \textsf{amsmath} 2, you must
-load \textsf{accents} after. Note that \textsf{amsmath} could redefine
-some accents; in particular, if you experience problems with |\vec|
-and you are using the standard math encodings, define:
-\begin{verbatim}
-\let\vec\relax
-\DeclareMathAccent{\vec}{\mathord}{letters}{"7E}
-\end{verbatim}
-\end{itemize}

-\Large Fixing (some) \textsf{babel} annoyances}
-
-\begin{document}
-
-\maketitle
-
-\begin{center}
-\fbox{\textbf{This package is deprecated. Use babel 3.9 and later instead.}}
-\end{center}
-
-The \textsf{babel} package introduces some changes in the \LaTeX{}
-kernel which are not strictly necessary (perhaps just convenient), but
-have some unwanted side-effects.  Oddly enough, most of these changes
-cannot be disabled, with a few exceptions (eg, \texttt{activeacute}
-and \texttt{activegrave}, but note there are not \texttt{activecaret}
-or \texttt{activetilde}). 
-
-With \textsf{babeltools} you can modify the \textsf{babel} behaviour
-by means of a set of package options, with a few macros serving as
-tools for specific purposes.  This package must be loaded
-\textbf{before} \textsf{babel}.
-
-\section{Package options}
-
-\begin{description}
-\item[shorthands=off] The shorthands mechanism is turned off.
-As some languages use this mechanism for tools not available
-otherwise, a macro \verb|\babelshorthand| is defined, which allows 
-using them; see below. 
-
-\item[shortands=...]  The shorthands mechanism is on, but the only
-shorthands activated are those given, like, eg:
-\begin{verbatim}
-\usepackage[shorthands=:;!?]{babeltools}
-\end{verbatim} 
-
-If \verb|'| is included, \texttt{activeacute} is passed to
-\textsf{babel}; if \verb|`| is included, \texttt{activegrave} is
-passed.  Active characters (like \verb|~|) should be preceded by
-\verb|\string| (otherwise they will be expanded by \LaTeX{} before
-they are passed to the package and therefore they will not be
-recognized).
-
-\item[adaptive] By default, all \textsf{babel} shorthands are active
-and live from start to end of documents.  You can deactivate them by
-hand with \verb|\shorthandoff|, but this is cumbersome and you cannot
-use it ``just in case'' (if the character is not a shorthands an error
-is raised, instead of ignoring silently the redundant setting).  That
-means you have to accept a character like : is active in an English
-document even if you need it for just a few quotations in French.  The
-default engine may be replaced by a new one which adapts the
-shorthands behaviour to the context in the following way:
-\begin{enumerate}
-\item In math mode, while still shorthands, they behave always like the
-corresponding normal char.  Things like \verb|$a \mathrel{x'} b$|
-work as expected.
-
-\item When the language is switched, shorthands chars are made normal or
-active, as appropriate.  Thus, \texttt{:} or \texttt{?}  are active only in
-\texttt{french}.
-\end{enumerate}
-
-% This option is useful when there are, say, short quotations in French
-% inside a German text or when there are whole chapter in either French
-% or German.
-
-\item[nocrossrefs] newlabel, ref and pageref are not redefined. You 
-cannot use shorthands in labels.
-
-\item[nocitations] nocite, bibcite and bibitem are not redefined. You 
-cannot use shorthands in labels.
-
-\item[langcaptions] Captions are redefined if possible so that an
-intermediate macro \verb|\lang...name| is used, eg,
-\verb|\germanchaptername|.  Somewhat experimental.
-
-\item[noconfig] Config files are not loaded, so you can make sure your
-document is not spoilt by an unexpected \texttt{.cfg} file.
-\end{description}
-
-Babel tweaks several packages for shorthands to be accepted.  At the
-time of this writing they are \textsf{cite}, \textsf{natbib},
-\textsf{varioref} and \textsf{hhline} (the latter for the colon).  If
-you don't use shorthands, these redefinitions are unnecessary and
-inconvenient.  If you give a list of shorthands and it doesn't include
-\verb|:|, then \verb|hhline| is left untouched.  The other packages
-are handled by \texttt{nocrossrefs} and \texttt{nocitations}, as
-appropriate.
-
-\section{Macros}
-
-\begin{description}
-\item[\ttfamily\string\babelshorthand] Use a shorthand, even with
-\texttt{shorthands=off} or not listed in it, eg,
-\verb|\babelshorthand{"u}| or \verb|\babelshorthand{:}|.  You can
-conveniently define your own macros.
-\end{description}
-
-\section{Known limitations}
-
-If a class loads \textsf{babel} with a language, you cannot use
-\textsf{babeltools}.  However, if a class loads babel without loading
-any language, you can use it.  Languages given in
-\verb|\documentclass| work as expected (provided the class doesn't
-load it, of course).

-\begin{document}
-\maketitle
-
-This document expains briefly the packages written by me and grouped
-under the Bezos directory in CTAN. They are in some sense small
-packages and this is the very reason they have been grouped here.
-Large packages like \textsf{gloss} (written with Jos\'e Luis D\'\i
-az), \textsf{titlesec} (including \textsf{titletoc}) and
-\textsf{enumitem} are under their own directories.
-
-\section{Accents}
-
-This package provides some miscellaneous tools for mathematical 
-accents, with the following goals in mind:
-\begin{itemize}
-\item Creating faked accents from non-accent symbols, like
-$\accentset{\star}{s}$.
-\item Grouping them, perhaps including actual accents, like 
-$\hat{\accentset{\star}{\hat h}}$. That
-has the side effect that multiple actual accents can be built
-as well.
-\item Putting them below the main symbol instead of above.
-\end{itemize}
-
-That is done so that the faked accents behave in quite similar fashion 
-to actual accents do; i.e., the skew of the letter is taken into 
-account (compare $\accentset{\ast}{d}$ with 
-$\accentset{\ast}{h}$) and the sub and superscripts attached to 
-it aren't misplaced (look carefully at $\accentset{\star}{f}_1^1$).
-
-The two basic commands are the following:
-\begin{decl}
-|\accentset{<accent>}{<symbol>}|
-\end{decl}
-Builds a faked accent, as for instance
-\begin{sample}
-|\accentset{\star}{d}|    \> $\accentset{\star}{d}$\\
-|\accentset{\diamond}{h}| \> $\accentset{\diamond}{h}$\\
-|\tilde{\accentset{\circ}{\phi}}| \>
-    $\tilde{\accentset{\circ}{\phi}}$
-\end{sample}
-
-\begin{decl}
-|\underaccent{<accent>}{<symbol>}|
-\end{decl}
-
-This command puts the |<accent>| under the |<symbol>|. Both real
-and faked accents are allowed. For instance,
-\begin{sample}
-|\underaccent{\hat}{x}|      \> $\underaccent{\hat}{x}$\\
-|\underaccent{\bar}{\gamma}| \> $\underaccent{\bar}{\gamma}$\\
-|\underaccent{\triangleright}{q}|  \>
-   $\underaccent{\triangleright}{q}$\\
-|\underaccent{\tilde}{\mathcal{A}}| \>
-    $\underaccent{\tilde}{\mathcal{A}}$
-\end{sample}
-
-Typeset \texttt{accents.tex} for further details.
-
-\section{Esindex}
-
-This package defines the command \verb|\esindex| which
-easies writing Spanish index entries:
-\begin{verbatim}
-\esindex{ca��n}
-\end{verbatim}
-is equivalent to
-\begin{verbatim}
-\index{can^^ffon@ca��n}
-\end{verbatim}
-This way, entries with diacritical marks are properly
-sorted. It has options to ignore spaces (letter-by-letter) and 
-particles, and to predefine sort keys.
-
-The manual is \texttt{esindex.tex} and is in Spanish.
-
-\section{Tensind}
-
-This package provides typographically fine tensorial notation, with
-the following features:
-\begin{itemize}
-\item Dots filling gaps. 
-
-\item Symbol subtitution to easy typing (if you are using greek
-letters, for example).
-
-\item Corrected position of indexes: horizontally, to compensate the
-small displacement in letters like $f$ (look carefully at $f_*^*$) and
-vertically, to avoid superscripts too raised.
-
-\item Aditional minute corrections are also allowed.
-\end{itemize}
-
-After setting a \textit{tensor delimiter} with \verb|\tensordelimiter|
-you can write tensorial indexes in a very compact way.  In subsequent
-examples we will assume
-\begin{verbatim}
-\tensordelimiter{?}
-\end{verbatim}
-and every instance of |?| will actually mean |<tensor-delim>|.
-
-Tha basic commands are the following:
-
-\begin{decl}
-|?[<format>]{<nucleous>}{<special-index>}...|\\
-|                       <super-or-sub>...?|
-\end{decl}
-
-Creates a tensor. A few examples will be illustrative:
-\begin{sample}
-|?R_ij^kl_\alpha^\beta?|     \>        $?R_ij^kl_\alpha^\beta?$\\[2pt]
-|?R^ij_kl^\alpha_\beta?|     \>        $?R^ij_kl^\alpha_\beta?$\\[2pt]
-|?R**_ij^kl_\alpha^\beta?|   \>        $?R**_ij^kl_\alpha^\beta?$\\[2pt] 
-|?R**^ij_kl^\alpha_\beta?|   \>        $?R**^ij_kl^\alpha_\beta?$
-\end{sample}
-
-The following letters may be used in format:
-\begin{itemize}
-\item[\texttt{l}] Gaps to the left of the last index are filled with dots.
-\item[\texttt{r}] Gaps to the right of the first index are filled.
-\item[\texttt{e}] If there is no index (empty), gaps are filled.
-\item[\texttt{b}] Only gaps in subscripts are filled.
-\end{itemize}
-(There are further options to set the vertical spacing.)
-\begin{sample}
-|?[]f\prime_ij^kl?|    \>  $?[]f\prime_ij^kl?$\\[2pt]
-|?[e]f^ij?|            \>  $?[e]f^ij?$ \\[2pt] 
-|?[l]f*_ij^kl?|        \>  $?[l]f*_ij^kl?$\\[2pt]
-\end{sample}
-
-Please, typeset \verb|tensind.tex| for further details.
-
-\section{Babeltools}
-
-\textbf{Deprecated.}
-
-\section{Subdocs}
-
-This is a tentative package aiming to provide a different approach for
-multidocument works (mainly, books with a document per chapter).
-Unlike the \verb|\include| mechanism, every subdocument is a complete
-normal \LaTeX{} document and can be typeset separately.  What the
-package does is sharing the \texttt{aux} files.  It's still an alpha version,
-and no attempt has been done yet to make it to work with, say,
-\textsf{hyperref}.
-
-This approach has the following advantages: 1) packages can be loaded
-just when a part requires them;  2) generated pdf/dvi/ps files are
-kept.
-
-You need a master tex file containing a \verb|\subdocuments| command
-listing the files.  With an optional argument you can set its
-behaviour:
-\begin{sample}
-|\subdocuments[clear=double]{file1, file2, file3}|
-\end{sample}
-
-The option \texttt{clear=double} adds an empty page at the end to give
-a even number of pages.  \texttt{clear=single} doesn't and it's the
-default.  Spaces and new lines before and after commas are ignored, as
-well as empty items.  It relies on the \textsf{keyval} package, so
-names containing \texttt{=} must be given within braces.  This file
-can be used as a shared preample, with common settings for all the
-documents.
-
-Documents must have the folowing line just after \verb|\documentclass|:
-\begin{sample}
-|\usepackage[master]{subdocs}|
-\end{sample}
-where \texttt{master} is the name of the file described above.
-
-Since every subdocument reads all the aux files, \verb|\tableofcontents|
-may be used where desired. 
-
-\section{Dotlessi}
-
-This package defines two commands: \verb|\dotlessi| and
-\verb|\dotlessj|, which give you access to dotless i's and j's in math
-mode.  They are intended for symbols in non English languages.  If the
-default math font is used, they are equivalent to \verb|\imath| and
-\verb|\jmath|; if a different font is used (like \verb|\mathrm|,
-\verb|\mathbf|, \verb|\mathsf|) these commands look in the
-corresponding font tables to find their codes.  In text mode, they
-expand to \verb|\i| and \verb|\j|.  For example:
-\begin{sample}
-|f_{\mathrm{m\acute{\dotlessi}n}}|   \>  
-$f_{\mathrm{m\acute{\dotlessi}n}}$
-\end{sample}
-
-\section{Checkend}
-
-When an environment is left open, \LaTeX{} gives an error at the end
-of the document.  However it only informs about the first of them,
-while the rest are shown with meaningless errors:
-\begin{verbatim}
-(\end occurred inside a group at level N)
-\end{verbatim}
-
-This package replaces them with more useful messages
-which show which environments (in reverse order) were
-not closed.
-
-That's all. There are no user macros. Just load the package.
-
-\section{Arabicfront}
-
-This package modifies the definitions of \verb|\frontmatter| and
-\verb|\mainmatter| so that  page numbering starts in arabic style from the
-front matter while preserving the rest of the original definitions.
-For it to work, \verb|\pagenumbering| has to be inside these macros --
-most of classes do that, but there are exceptions like
-\textsf{memoir}.
-
-To use it, just \verb|\usepackage{arabicfront}|.
-
-\section{Soulpos}
-
-This package just combines \textsf{soul} with the \texttt{savepos}
-mechanism provided by the pdftex engine, so that you can create
-(almost) arbitrary underlining and similar ``decorations'', including
-rules, leaders and even pictures (\textsf{pgf}, \textsf{pstricks},
-etc.). Unlike \textsf{soul} underlines, which are built by repeating small
-elements, here each chunk of text to be underlined is a single
-element.
-
-A basic underlining is:
-\begin{verbatim}
-\ulposdef{\uline}{\rule[-.8ex]{\ulwidth}{.5pt}}
-\end{verbatim}
-
-% \section{Esbst}
-% 
-% This file was formerly included in the Spanish style for
-% babel but from version 5.0 on (not yet released) it will
-% be a separate package.

-
-\maketitle
-
-This package defines the command \verb|\esindex| which eases writing
-Spanish index entries:
-\begin{verbatim}
-\esindex{cañón}
-\end{verbatim}
-is equivalent to
-\begin{verbatim}
-\index{can^^ffon@cañón}
-\end{verbatim}
-As you can see, the package generates the sort key within \TeX{}
-itself, which has a number of advantages.
-
-Although it is a specifically Spanish tool (so most of the
-documentation is in Spanish), the idea behind this package may be
-applied to other languages, and tools to adapt it are provided, too.
-They are explained below.
-
-Version 1.5 provides tools for other languages and adds support for
-\textsf{luatex} and \textsf{xetex}.
-
-\section{Spanish}
-
-Este paquete ha sido diseñado para facilitar la escritura de índices
-correctamente alfabetizados en castellano. Su principal orden es
-\verb|\esindex|, que convierte a una forma adecuada su argumento. Así
-por ejemplo,
-\begin{verbatim}
-\esindex{cañón}
-\end{verbatim}
-equivale a
-\begin{verbatim}
-\index{can^^ffon@cañón}
-\end{verbatim}
-No es necesario usar \textsf{babel} salvo, lógicamente, si los acentos
-están escritos en forma de abreviaciones (\verb|'a|, \verb|'e|, etc.)
-en lugar de con los caracteres reales. En este último caso, el paquete
-utiliza ciertas órdenes internas de \textsf{babel}, por lo que no puedo
-garantizar su funcionamiento correcto con versiones distintas a las 3.6
-a 3.27. En caso de que \textsf{esindex} sea incompatible con futuras
-versiones de \textsf{babel} (lo cual no es realmente probable)
-intentaré adaptarlo en el menor tiempo posible.
-
-Salvo el carácter \verb|actual| (normalmente \verb|@|) se pueden usar
-todos los caracteres especiales de \textit{MakeIndex}. Se pueden
-aplicar convenciones diferentes a las normales, pero en este caso hacen
-falta ajustes adicionales en caso de que los modificados sean
-\verb|actual|, \verb|encap|, \verb|level| o \verb|quote|. En ese caso
-basta con indicar los caracteres que hay que usar como opciones de
-paquete. Por ejemplo, si para \verb|quote| decidimos usar \verb|$| en
-nuestro archivo \verb|.ist| particular, tendríamos que llamar al
-paquete del siguiente modo:
-\begin{verbatim}
-\usepackage[quote=$]{esindex}
-\end{verbatim}
-
-Es importante observar que, a diferencia de la opción para alemán de
-\textit{MakeIndex}, el uso de \verb|"| en abreviaciones como \verb|"u|
-es completamente legítimo, ya que el paquete reconoce tal combinación y
-la trata aparte. Lo mismo vale para \verb|'| o \verb|~| en caso de que
-se usaran como carácter especial. Es decir
-\begin{verbatim}
-\esindex{{"!`}Cig"ue'nas{"!}|textbf}
-\end{verbatim}
-equivale a
-\begin{verbatim}
-\index{{"!`}Ciguen^^ffas{"!}@{"!`}Cig\"ue\~nas{"!}|textbf}
-\end{verbatim}
-
-Sin embargo, el uso del carácter \verb|quote| ante \verb|encap| o
-\verb|level| no se detecta a menos que el grupo esté encerrado entre
-llaves. Por ejemplo, en lugar de \verb/\esindex{Pleca: "|}/ debe
-escribirse \verb/\esindex{Pleca: {"|}}/. (En realidad en este caso
-podría haberse usado \verb|\index|. Es tan sólo un ejemplo.)
-
-Aunque el hecho de que \verb|@| no se pueda usar en \verb|\esindex|
-hace que todavía algunas entradas se tengan que hacer a mano, la mayor
-parte del trabajo se ve considerablemente simplificado.
-
-Finalmente, hay que señalar que con este paquete no se crea en el
-índice una entrada propia para la palabras que empiezan por eñe, sino
-que tan sólo se añaden al final de la ene. En el rarísimo caso de que
-hubiera palabras que empiezan por eñe habría que modificar el archivo
-\verb|.ind| a mano o bien redefinir de algún modo las entradas
-generadas.
-
-La versión 1.3 elimina una incompatibilidad con recientes versiones de
-\LaTeX{} y añade nuevas funciones:
-\begin{itemize}
-\item Opción de paquete \verb|ignorespaces|: al formar la clave de 
-ordenación se suprimen los espacios, de forma que:
-$$\mbox{adentro} < \mbox{a donde} = \mbox{adonde}.$$
-\item Opción de paquete \verb|replaceindex|: el comportamiento de
-\verb|\index| se reemplaza por el de \verb|\esindex|, aunque en este
-caso no es posible introducir entradas que no se adapten a lo
-requerido por \verb|\esindex|.
-\item La orden \verb|\ignorewords| da
-una lista de palabras separadas por comas que no se cuentan en la
-ordenación.  Por ejemplo, con \verb|\ignorewords{de}| tendríamos:
-$$\mbox{pino albar} < \mbox{pino laricio} < \mbox{pino de montaña}.$$
-Distingue la caja, por lo que las formas con mayúsculas hay que darlas
-explícitamente, si hicieran falta.
-\end{itemize}
-
-Algunas funciones adicionales son:
-\begin{itemize}
-\item La lista de tókenes \verb|\everyesindex| permite dar definiciones
-locales para establecer el comportamiento de otras órdenes. Por
-ejemplo:
-\begin{verbatim}
-\everyesindex{\renewcommand\emph[1]{#1}}
-\end{verbatim}
-elimina de la clave esa orden. Con:
-\begin{verbatim}
-\everyesindex{\renewcommand\emph[1]{#1'}}
-\end{verbatim}
-la entrada en cursiva iría detrás de la redonda, si la hubiera. Es una
-técnica que se puede emplear en otros casos para reajustar el orden de
-entradas idénticas.
-
-\item La orden \verb|\esindexsort| permite predefinir claves asociadas
-a entradas concretas, para ajustar su ordenación (lo que normalmente se
-consigue añadiendo texto adicional para que makeindex lo tenga en
-cuenta). Estas correspondencias deben darse antes de la aparición del
-primer \verb|\esindex| con ese término, y las claves se procesan
-posteriormente con \verb|ignorespaces|, \verb|\ignorewords| y
-\verb|\everyesindex|, si están activadas. Por ejemplo:
-\begin{verbatim}
-\esindexsort{adonde}{adonde'1}
-\esindexsort{adónde}{adonde'2}
-\esindexsort{a donde}{a donde'7}
-\esindexsort{a dónde}{a donde'8}
-\end{verbatim}
-daría el orden \emph{adonde, adónde, a donde, a dónde}, con
-\verb|ignorespaces|, o bien \emph{a donde, a dónde,} [probablemente
-otros términos], \emph{adonde, adónde}, sin \verb|ignorespaces|.
-\end{itemize}
-
-\section{Other languages}
-
-First, you very likely want to ignore de Spanish specific settings with
-the package option \verb|nospanish|. What \verb|\esindex| does is the
-following:
-
-\begin{enumerate}
-\item Replacements set by \verb|\esindexsort|. See an example above.
-
-\item \verb|\esindexreplace| in \verb|\everyesindex|. See an example
-below.
-
-\item Replacements by \LaTeX{} (protected) expansion, including
-redefinitions in \verb|\everyesindex| and, in Spanish, \verb|\`|,
-\verb|\"| and \verb|\~|. You may force protected expansion at any point
-inside \verb|\everyesindex| with \verb|\esindexexpandkey|. In addition,
-the sort key is stored in \verb|\esindexkey|, which can be manipulated
-directly.
-
-\item Removal of words listed in \verb|\ignoredwords| (maybe not the
-logical place, but real life is not always logical). For example, with
-\verb|\ignorewords{de,la}| the words “de” and “la” (preceded and
-followed by spaces) are removed from the key.
-
-\item Removal of spaces if \verb|ignorespaces|. Very often this is
-similar to the \verb|-l| option of \textit{MakeIndex}.
-
-\item Replacement of `actual' as set by \verb|\esindexactual|, but
-still based on the original \verb|\esindex| argument, without changes.
-For example, with:
-\begin{verbatim}
-\esindexactual{Felipe II}{Felipe II, \textit{rey de España}}
-\end{verbatim}
-just write \verb|\esindex{Felipe II}| (as many times as you want), and
-the entry will show “Felipe II, \textit{rey de España}” (the sort key
-is still based on “Felipe II”, of course).
-
-\end{enumerate}
-
-Do you find it chaotic? Well, you are right. After all this package is
-for Spanish indexes with some readjustments for it to be adapted to
-other languages. A general solution deserves another package. Feel free
-to create one based on this package (MIT license), if you like.
-
-Here is an example of an \verb|\everyesindex|. Like other
-\verb|\every...|'s, it is a token register:
-\begin{verbatim}
-\everyesindex{%
-  \renewcommand\"[1]{#1e}%
-  \renewcommand\textit[1]{#1}%
-  \esindexexpandkey
-  \esindexreplace{ä}{ae}%
-  \esindexreplace{ü}{ue}%
-  \esindexreplace{ö}{oe}}
-\end{verbatim}
-
-What it does is:
-\begin{enumerate}
-\item Redefines \verb|\textit| so that it is removed to build the key.
-With \verb|\everyesindex{\renewcommand\textit[1]{#1'}}| italics would
-be sorted after upright.
-
-\item Redefines \verb|\"|. Of course, this only works correctly if used
-for this precise expansion.
-
-\item Applies the previous changes with a protected expansion.
-
-\item Make a direct replacement of some characters.
-
-\end{enumerate}
-Remember these changes are not shown -- they are used by
-\textit{MakeIndex} to sort the entries. Note also replacements can be
-language dependent with the appropriate test (eg, with
-\textsf{iflang}).
-
-As a convenience tool, \verb|\esindexlastchar| is \verb|^^ff| or
-\verb|^^^^ffff|, depending on the engine.

-\maketitle
-
-This package just combines \textsf{soul} with the \texttt{savepos}
-mechanism provided by the pdftex engine, so that you can create
-(almost) arbitrary underlining and similar ``decorations'', including
-rules, leaders and even pictures (\textsf{pgf}, \textsf{pstricks},
-etc.). Unlike \textsf{soul} underlines, which are built by repeating small
-elements, here each chunk of text to be underlined is a single
-element.
-
-The main drawback is obvious -- since it relies on \verb|\pdfsavepos|
-two passes are necessary.  Further, to prevent exhausting the hash
-table, the auxiliary file containing the information about each
-underline is read only when needed, which may impact performance
-negatively.\footnote{Actually, two files are created, with extensions
-\texttt{upa} and \texttt{upb}.}
-
-Internally \textsf{soul} knows to some point where a break happens,
-and this information may be used to set diferent styles depending on
-the position.
-
-This version (1.0) does almost no checking (e.g., to warn about the
-need for a new run), which is left for a later release.
-
-The package \textsf{soulutf8} is loaded if it (or \textsf{soul}) has 
-not been loaded before (note the UTF-8 encoding is not necessary for
-\textsf{soulutf8} to work).
-
-\section{Usage}
-
-Underlining macros are defined much like in \textsf{soul}.
-
-\begin{desc}
-\verb|\ulposdef{<name>}[<options>]{<commands>}|
-\end{desc}
-
-Defines an underline as \verb|<commands>|, which is placed in a box of
-width zero with either \verb|\llap| or \verb|\rlap|, as explained
-below.  Typically, \verb|<commands>| will contain a rule or leaders.
-If the text spans more than one line, then there will be several
-chunks to be undelined (one per line).
-
-You can use the following macros in \verb|<commands>|.
-
-\begin{desc}
-\verb|\ulwidth|
-\end{desc}
-
-The width of the text block to be underlined. A basic underlining is:
-\begin{verbatim}
-\ulposdef{\uline}{\rule[-.8ex]{\ulwidth}{.5pt}}
-\end{verbatim}
-
-\begin{desc}
-\verb|\ifulstarttype{<type>}{<true>}{<false>}|\qquad
-\verb|\ifulendtype{<type>}{<true>}{<false>}|
-\end{desc}
-
-These tests can be used in \verb|<commands>|, to set different underlining
-styles depending on where the current chunk begins or ends.  Here
-\verb|<type>| is: 0 if the very start or end of the underlined text, 1 if a
-space, 2 if a discretionary hyphen and 3 if an explicit hyphen. See 
-an example below.
-
-\begin{desc}
-\verb|\ulstarttype|\qquad\verb|\ulendtype|
-\end{desc}
-
-Macros storing the values described above, so that you can use
-\LaTeX{} conditionals (or \TeX{} ones). So, to check if the end is an
-hyphen, test \verb|\ulendtype>1|.
-
-\vskip2ex
-\hrule
-\vskip2ex
-
-Valid keys/values in \verb|<options>| are:
-
-\begin{description}
-\item[\texttt{xoffset}]
-This key provides a simple way to fix an unpleasant effect found in
-many programs when colouring the text background -- the colour starts
-and ends just at the edges of the first and last characters.  Just set
-the offset to a value larger than 0pt, as for example .1 em.  This
-value is added ($\times$2) to \verb|\ulwidth|, but no space is added
-to the text (which can be done with the \verb|gap| key).  Of course,
-you can still do finer adjustments in the definition of the underline,
-as shown in the samples below. You can use \verb|xoffset-start| and 
-\verb|xoffset-end| to set the corresponding values separately.
-
-\item[\texttt{gap}] It is equivalent to the outer space in
-\verb|\sodef|.  This value is \textit{not} added to \verb|\ulwidth|.
-You can use \verb|gap-start| and \verb|gap-end| to set the
-corresponding values separately.
-
-\item[\texttt{hyphens}] Sometimes excluding the hyphen from the
-underlined text could make sense.  Default is \verb|hyphens=include|
-but you can set it to \verb|hyphens=exclude|.
-
-\item[\texttt{overdraw}] By default underlines are drawn before the
-text is typeset (with \verb|\rlap|), so that they are placed behind.
-However, it can be drawn after (with \verb|\llap|), on top the text,
-with \verb|overdraw| or, equivalently, \verb|overdraw=true| (default
-is \verb|overdraw=false|).
-\end{description}
-
-\begin{desc}
-\verb|\ulpostolerance|
-\end{desc}
-
-The current algorithm is based on changes of the $y$ coordinate of
-savepos and therefore presumes a regular baseline.  Any increasing or
-decreasing of $y$ is considered a new chunk, but you can give a certain
-tolerance with, for example:
-\begin{verbatim}
-\renewcommand{\ulpostolerance}{12}
-\end{verbatim}
-
-\section{Future work}
-
-\begin{itemize}
-\item Warnings. 
-\item In short documents, providing an option for using the aux file.
-\item Redefinable macros.
-\item \texttt{offset}, including edges at line breaks.
-\item \texttt{.upb} is generated at the end of the run, so it might be
-used by another program to generate the decorations.  As of 1.0.
-however, its syntax is likely to change and therefore unsupported.
-\item Better manual.
-\item Improved performance.
-\item Fixing some issues in multicolumn text (it does not work if there 
-are just two lines, one at the left and the other at the right).
-\item Some predefined ``decorations''.
-\end{itemize}
-
-\newcommand\ulpossample[1]{%
-A single #1{word}.  Now #1{a few words}.  Longer:
-#1{this text spans several lines, so that you can see the behaviour of
-\textsf{soulpos} where there are line breaks}.\vskip2ex\hrule\vskip2ex}

-\maketitle
-  
-This package provides typographically fine tensorial notation, with the 
-following features:
-\begin{itemize}
-\item Dots filling gaps.
-\item Symbol subtitution to easy typing (if you are using greek letters, for 
-example).
-\item Corrected position of indexes: horizontally, to compensate the small 
-displacement in letters
-like $f$ (look carefully at $f_*^*$) and vertically, to avoid superscripts 
-too raised.
-\item Aditional minute corrections are also allowed.
-\end{itemize}
-
-\section{User Interface}
-
-\begin{decl}
-|\tensordelimiter{<tensor-delim>}|
-\end{decl}
-
-Defines |<tensor-delim>| to be a tensor delimiter. In subsequent examples we will 
-assume
-\begin{verbatim}
-\tensordelimiter{?}
-\end{verbatim}
-and every instance of |?| will actually mean |<tensor-delim>|.
-
-\begin{decl}
-|?[<format>]{<nucleous>}{<special-index>}{<special-index>}...|\\
-|                       <super-or-sub><super-or-sub>...?|
-\end{decl}
-
-Creates a tensor. |<super-or-sub>| is either |_{<index>}{<index>}...| or 
-|^{<index>}{<index>}|.
-|<nucleous>| is the symbol which indexes will be add to. |<special-index>| is a 
-superscript which is neither covariant nor contravariant (dual, 
-prime...). In 
-one-letter |<index>|, |<special-index>| or |<nucleous>|, curly braces can be 
-omitted.
-For example:
-\begin{sample}
-|?R_ij^kl_\alpha^\beta?|     \>        $?R_ij^kl_\alpha^\beta?$\\[2pt]
-|?R^ij_kl^\alpha_\beta?|     \>        $?R^ij_kl^\alpha_\beta?$\\[2pt]
-|?R**_ij^kl_\alpha^\beta?|   \>        $?R**_ij^kl_\alpha^\beta?$\\[2pt] 
-|?R**^ij_kl^\alpha_\beta?|   \>        $?R**^ij_kl^\alpha_\beta?$
-\end{sample}
-
-(\emph{Don't forget the closing |?|!})
-Finally, |<format>| changes the format in a tensor. (See |\tensorformat| 
-below.)
-
-\begin{decl}
-|\tensorformat{<format>}|
-\end{decl}
-
-The following letter may be used in format.
-\begin{itemize}
-\item[\texttt{l}] Gaps to the left of the last index are filled with dots.
-\item[\texttt{r}] Gaps to the right of the first index are filled.
-\item[\texttt{e}] If there is no index (empty), gaps are filled.
-\item[\texttt{b}] Only gaps in subscripts are filled.
-\end{itemize}
-
-Sensible settings are: none (no dots), |l| and |lrb|.
-Further options are:
-\begin{itemize}
-\item[\texttt{c}] Brings index lines closer.
-\item[\texttt{o}] Opens index lines.
-\item[\texttt{s}] Styled. |o| in display style and |c| otherwise.
-\end{itemize}
-These options are mutually exclusive. If none of them is
-used, then indexes behave in a similar way to standard ones.
-This document sets
-\begin{verbatim}
-\tensorformat{lrb}
-\end{verbatim}
-
-\begin{sample}
-|?[]f\prime_ij^kl?|    \>  $?[]f\prime_ij^kl?$\\[2pt]
-|?[e]f^ij?|            \>  $?[e]f^ij?$ \\[2pt] 
-|?[l]f*_ij^kl?|        \>  $?[l]f*_ij^kl?$\\[2pt]
-|?[c]R^ij_kl?|         \>  $?[c]R^ij_kl?$
-\end{sample}
-
-\begin{decl}
-|\indexdot|
-\end{decl}
-
-This macro is the index dot. Defined to |\cdot|. You can
-redefine it with |\renewcommand|.
-
-\begin{decl}
-|\whenindex{<index>}{<new-index>}{<commands>}|
-\end{decl}
-
-Automatically replaces |<index>| (if not enclosed in braces)
-by |<new-index>| and the additional |<commands>| are
-executed. For example, if you like to use greek indexes:
-\begin{verbatim}
-\whenindex{a}{\alpha}{}
-\whenindex{b}{\beta}{}
-\whenindex{g}{\gamma}{}
-\end{verbatim}
-
-\whenindex{a}{\alpha}{}
-\whenindex{b}{\beta}{}
-\whenindex{g}{\gamma}{
-}
-A |\whenindex{'}{\prime}{}| is performed by the package. For instance
-\begin{sample}
-|?R'_ijk^abg?|    \>  $?R'_ijk^abg?$
-\end{sample}
-
-In |<commands>|, two command for space fine-tuning are provided:
-|\sbadjust{<index>}{<comma-space>}| adds |<comma-space>| times
-|\,| before the current subscript index if the last superscript index
-was |<index>|. Similarly, |\spadjust| adds the space before the current
-superscript index if the last subscript index was |<index>|.
-For instance, the normal result of |?[]R^ik_lm?| is $?[]R^ij_kl?$, but
-with
-\begin{verbatim}
-\whenindex{k}{k}{\sbadjust{j}{-1}}
-\end{verbatim}
-\whenindex{k}{k}{\sbadjust{j}{-1}}
-is $?[]R^ij_kl?$.
-These commands will be ignored if dots are used.
-
-Two further command allowed in |\whenindex|
-are: |\omitdot| omits the dot for the current
-index, and |\finishdots| omits as well all subsequent indexes.
-For example
-\begin{verbatim}
-\whenindex{;}{\,;\,}{\finishdots}
-\end{verbatim}
-\whenindex{;}{\,;\,}{\finishdots}
-
-\begin{sample}
-|?[lr]A*_i^kl;i?|  \>   $?[lr]A*_i^kl;i?$
-\end{sample}
-
-\begin{decl}
-|tensor|
-\end{decl}
-
-The environment called by |?...?|. Useful if for some reason you
-don't want an equivalent defined with |\tensordelimiter| . Example:
-\begin{verbatim}
-\begin{tensor}[lr]A*_i^kl;i\end{tensor}
-\end{verbatim}
