+\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.
