+Spanish for babel
+=================
+
+Este directorio es un lugar permanente para la última versión
+oficial del estilo babel para la lengua castellana. Hay que
+advertir que los archivos incluídos en la distribución de babel,
+pueden estar desfasados, y a menudo lo están.
+
+El directorio contrib, como su nombre sugiere, no es parte del
+lote oficial.
+
+------------------
+
+This directory is a permanent place for the latest official release
+of the babel style for the Spanish language. Note the files bundled
+with the babel distribution could be, and very often are, outdated.
+
+The contrib directory, as its name implies, is not part of the
+official bundle.
+
+History
+~~~~~~~

+Reimplemented in full, which some parts rewritten from scratch.  Added
+the es- mechanism and the mexico option.  Many bug fixes
+
+5.0d. 2008-05-25

+with \roman and hyperref
+
+5.0e. 2008-07-06 (in babel: 2008-07-06)
+Fixed '', which gobbled the space following.

+% {\small\tableofcontents}
+%
+% \section*{Símbolos empleados}
+%
+% \begin{itemize}
+% \item[\textcolor{blue}{$\Rightarrow$}] Macros para 
+% ser usadas en el texto.
+% \item[\textcolor{magenta}{$\star$}] Macros de 
+% configuración y preferencias.
+% \item[\textcolor{green}{$\surd$}] Grupo que 
+% activa la orden.
+% \item[\textcolor{red}{$\times$}] Opciones de 
+% paquete que anulan la orden. En redonda van las destinadas 
+% específicamente a anular ese punto, y en cursiva las que además
+% anulan otros aspectos del estilo.
+% \end{itemize}
+%
+% \section{Uso de \textsf{spanish} para babel}
+%
+% El estilo de \textsf{spanish} para babel tiene con finalidad adaptar una
+% serie de elementos de los documentos de \LaTeX\ al castellano, 
+% tanto en las traducciones como en la tipografía. Para
+% usarlo, basta con emplear la opción \textsf{spanish} al cargar babel:
+%\begin{verbatim}
+%\usepackage[spanish]{babel}
+%\end{verbatim}
+%
+% Esto es todo lo que hace falta para conseguir que el documento tenga
+% un aspecto español. En caso de estar en México, véase, además, el
+% apartado \ref{paises} (<<Opciones por países>>):\footnote{En próximas
+% versiones se añadirán más países.}
+%\begin{verbatim}
+%\usepackage[spanish,mexico]{babel}
+%\end{verbatim}
+%
+% El estilo \textsf{spanish} se puede cargar junto con otras lenguas (véase el 
+% manual de babel). Si \textsf{spanish} es la última de las lenguas cargadas,
+% entonces se considera la lengua principal y se hacen una serie de
+% ajustes tipográficos adicionales. En particular, se modifican
+% órdenes y entornos como:
+%\begin{center}
+%\begin{tabular}{lll}
+%  |enumerate| &  |\roman|    &  |\section| \\
+%  |itemize|   &  |\fnsymbol| &  |\subsection|\\
+%  |\%|        &  |\alph|     &  |\subsubsection|\\
+%                  &  |\Alph|     & \\
+%\end{tabular}
+%\end{center}
+%
+% El estilo está pensado para que sea muy configurable.  Para ello, se
+% proporcionan una serie de opciones de paquete, que en caso de
+% emplearse deben ir \textit{después} de \textsf{spanish}.  Por
+% ejemplo:
+% \begin{verbatim}
+% \usepackage[french,spanish,es-noindentfirst]{babel} \end{verbatim}
+% carga los estilos para el francés y el español, esta última como
+% lengua principal; además, evita que \textsf{spanish} sangre el
+% primer párrafo tras un título.  Otras opciones se pueden ajustar por
+% medio de macros, en particular aquellas que se puede desear cambiar
+% en medio del documento (por ejemplo, el formato de la fecha).
+%
+% Los cambios están organizados en una serie de grupos: 
+% \textsf{captions, date, text, math} y \textsf{shorthands}.
+% Los tres ultimos corresponden a lo que en babel sería normalmente
+% \textsf{extras}.
+%
+% \section{\textsf{spanish} como lengua principal}
+% 
+% Si la lengua principal es \textsf{spanish}, se introducen una serie de
+% cambios en el momento de cargar la lengua para adaptar varios
+% elementos a los usos tipográficos españoles.  Estos cambios
+% funcionan con las clases estándar "+--con otras tal vez alguno de
+% ellos no tenga efecto--- y persisten durante todo el documento.
+% Ninguno de ellos es necesario para componer el documento, aunque
+% naturalmente el resultado será distinto.
+%
+% \subsection{Listas}
+%
+% \begin{decl} \txt |\begin{enumerate} ... \end{enumerate}|%
+% \deact{es-nolists, es-noenumerate, \textit{es-nolayout, es-minimal,
+% es-sloppy}} \end{decl}

+% \quad 1.\\
+% \qquad \emph{a})\\
+% \quad\qquad 1)\\
+% \qquad\qquad \emph{a$'$})
+%
+% \begin{decl} \txt |\begin{itemize} ... \end{itemize}|%
+% \deact{es-nolists, es-noitemize, \textit{es-nolayout, es-minimal,
+% es-sloppy}} \end{decl}
+%
+% Usa la siguiente secuencia:\\
+% \quad\leavevmode\hbox to 1.2ex
+%     {\hss\vrule height .95ex width .8ex depth -.15ex\hss}\\
+% \qquad\textbullet\\
+% \quad\qquad $\circ$\\
+% \qquad\qquad $\diamond$
+%
+% \begin{decl}
+% \con  |\spanishdashitems    \spanishsignitems|
+% \end{decl}
+%
+% Dos órdenes  para cambiar a otros estilos en
+% |itemize|: rayas en todos los niveles y \textbullet{} $\circ$
+% $\diamond$ $\triangleright$, respectivamente.
+%
+% \begin{decl}
+% \con  |es-nolists|\opp
+% \end{decl}
+%
+% Desactiva los cambios en las listas (aunque  |\es@enumerate| y 
+%  |\es@itemize| siguen disponibles).
+%
+% \subsection{Contadores}
+% 
+% \begin{decl}
+% \txt |\alph    \Alph|\deact{\textit{es-nolayout, es-sloppy}}
+% \end{decl}
+%
+% Incluyen la eñe.
+%
+% \begin{decl}
+% \txt  |\fnsymbol|\deact{\textit{es-nolayout, es-sloppy}}
+% \end{decl}
+%
+% Se emplean uno, dos, tres... asteriscos (*, **, ***, etc.),
+% en lugar de la sucesión angloamericana de cruces, barras,
+% etc.\footnote{\DOT{162}.}
+%
+% \begin{decl}
+% \txt  |\roman|\deact{es-ucroman, es-lcroman, \textit{es-nolayout, es-minimal, es-sloppy}}
+% \end{decl}
+%
+% Como en castellano no se usan números romanos en minúscula,
+% |\roman| se redefine para que los dé en
+% versalitas.\footnote{\DTL{197}.} La opción de paquete
+%  |es-minimal| los desactiva con  |es-ucroman|, y |es-sloppy|
+% con  |es-lcroman|.
+
+% \begin{decl}
+% \con  |es-ucroman|\opp
+% \end{decl}
+%
+% Opción de paquete adicional, que pasa todos los romanos a versales,
+% en caso de que no se quiera la versalita o por incompatibilidad con
+% algún paquete que use de forma indebida  |\roman|.\footnote{En
+% el momento de escribir esto, como mínimo son: \textsf{dramatist,
+% epiolmec, flashcards, lipsum, ntheorem, ntheorem-hyper,
+% texmate.} Otros paquetes como \textsf{hyperref, easy} y \textsf{exam} 
+% ya han sido corregidos.}
+%
+% \begin{decl}
+% \con  |es-lcroman|\opp
+% \end{decl}
+%
+% Como último recurso, de haber problemas con el valor predeterminado
+% o con  |es-ucroman|, con esta opción de paquete puede dejarse la
+% definición de \LaTeX, aunque en español los romanos en minúscula
+% sean una falta ortográfica.
+%
+% \begin{decl}
+% \con  |es-preindex|\opp
+% \end{decl}
+%
+% \textit{MakeIndex} no puede entender la forma en que |\roman|
+% escribe el número de página, por lo que elimina las líneas
+% afectadas.  Por ello el archivo |.idx| ha de ser convertido antes de
+% procesarlo con \textit{MakeIndex}.  Con este paquete se proporciona
+% la utilidad |romanidx.sty| que se encarga de ello.  Simplemente se
+% compone ese archivo con \LaTeX{} y a continuación se responde a las
+% preguntas que se formulan; el archivo resultante, es decir, el que
+% hay que procesar con \textit{MakeIndex,} tiene la extensión
+% \texttt{eix}.  Este proceso no es necesario si no se introdujo
+% ninguna entrada de índice en páginas numeradas con |\roman| (lo
+% cual será lo más normal).  Si un símbolo propio de
+% \emph{MakeIndex} generara problemas, debe encerrarse entre llaves:
+% \verb={"|}=.
+%
+% Con la opción de paquete  |es-preindex| se llama desde el
+% documento |romanidx.sty|, de forma que no es necesaria su ejecución
+% aparte. Tampoco pide ningún dato, sino que ha de darse en el 
+% documento principal con la siguiente orden.
+%
+% \begin{decl}
+% \con  |\spanishindexchars|\marg{encap}\marg{open\_range}\marg{close\_range}
+% \end{decl}
+%
+% De usarse |es-preindex| con un estilo de índice que no tiene los
+% valores predeterminados de estos tres caracteres especiales, hay que
+% darlos con esta orden (es decir, por omisión es
+% \verb+\spanishindexchars{|}{(}{)}+).
+%
+% \begin{decl}
+% \con  |\spanishscroman    \spanishlcroman    \spanishucroman|
+% \end{decl}
+%
+% Finalmente, tres macros permiten cambios temporales en el
+% documento de  |\roman| a versalitas, minúsculas y mayúsculas,
+% respectivamente.
+%
+% \subsection{Otros}
+%
+% \begin{decl}
+% \txt  |\guillemotleft    \guillemotright|\deact{\textit{es-nolayout, es-sloppy}}
+% \end{decl}
+%
+% Las comillas latinas para |OT1| son menos angulosas y se generan
+% con unas puntas de flecha de |lasy|. En T1 no hay cambios.
+%
+% \begin{decl}
+% \txt  |\section|, |\subsection|, etc., 
+% |\tableofcontents|\deact{es-nosectiondot, es-noindentfirst, \textit{es-nolayout, 
+% es-mininal, es-sloppy}}
+% \end{decl}
+%
+% Los números en los títulos están seguidos de un punto 
+% tanto en el texto como en el índice. Además,
+% el primer párrafo tras el título no elimina la sangría.
+% 
+% \begin{decl}
+% \con  |es-nolayout|\opp
+% \end{decl}
+% 
+% Si no se desea ninguno de estos cambios, basta con usar esta opción 
+% de paquete.
+%
+% \section{Traducciones}
+%
+% \subsection{Nombres}
+% 
+% \begin{decl}
+% \txt  |\refname|, |\tablename|, |\contentsname|, etc.\\
+% \con  |\spanishrefname|, |\spanishtablename|, |\spanishcontentsname|, etc.
+% \act{captions}
+% \end{decl}
+%
+%    Establecen las traducciones al castellano de algunos términos,
+%    tal y como se describe en el cuadro 1.  Para cambiar el texto
+%    de ellas, conviene redefinir la forma que empieza con
+%     |\spanish...|, ya que, al contrario que las órdenes
+%    |\refname|, |\abstractname|, etc., se pueden redefinir cuando
+%    se desee y entran en acción al momento y de forma permanente, sin
+%    necesidad de |\addto|.

+% \con  |es-tilden|\opp
+% \end{decl}
+% 
+% Esta orden activa las abreviaciones |~n| y |~N| por compatibilidad
+% con versiones anteriores de \textsf{spanish} (y siempre que no se
+% empleado también |es-notilde|). En la versión 5 no están
+% activadas de forma predeterminada.
+% 
+% \begin{decl}
+% \con  |\spanishdeactivate|\marg{caracteres}
+% \end{decl}
+% 
+% Permite desactivar las abreviaciones correspondientes a los
+% caracteres dados. Para evitar entrar en conflicto con otras lenguas,
+% al salir de \textsf{spanish} se reactivan,\footnote{El punto para
+% los decimales no es estrictamente una abreviación y no se
+% reactiva.} por lo que si se desea que 
+% persistan hay que añadir la orden a |\shorthandsspanish| con 
+%|\addto|. La orden |\renewcommand\shorthandsspanish{}| es una 
+% variante optimizada de
+%\begin{verbatim}
+% \addto\shorthandsspanish{\spanishdeactivate{.'"~<>}}
+%\end{verbatim}
+%
+% \begin{decl}
+% \con  |es-noshorthands|\opp
+% \end{decl}
+%
+% No activa ninguna  abreviación.
+% 
+% \subsection{Coma decimal}
+%
+% \begin{decl}
+% \txt  |.|\textit{número}\act{shorthands}\deact{es-nodecimaldot, 
+% \textit{es-noshorthands, es-minimal, es-sloppy}}
+% \end{decl}
+%
+% En \textsf{spanish}, el punto en matemáticas sirve como marca decimal
+% genérica que puede representarse como coma o punto; funciona
+% por tanto como marcado lógico del signo para decimales. Por
+% omisión, se siguen las normas internacionales ISO y la legislación
+% de diversos países (como de España y México) de emplear la coma.
+% Ya que \TeX\ usa la coma como separador en intervalos o expresiones 
+% similares, lo que añade un espacio fino, \textsf{spanish}
+% interpreta todo punto en modo matemático de esta forma siempre
+% que esté seguido de una cifra, pero no en otras circunstancias:
+% \begin{quote}\small\begin{tabbing}
+% |$1\,234.567\,890$|     \quad \=  $1\,234.567\,890$\\
+% |$f(1,2)=12.34.$|        \> $f(1,2)=12.34.$\\
+% |$1{.}000$|              \> $1{.}000$, pero\\
+% |1.000|                  \> 1.000, pues no es modo matemático.
+% \end{tabbing}\end{quote}
+%
+%
+% \begin{decl}
+% \con  |\decimalcomma    \decimalpoint    \spanishdecimal|\marg{math}
+% \end{decl}
+%
+% Las dos primeras establecen si se usa una coma (predeterminado)
+% o un punto, mientras que |\spanishdecimal|\marg{math}
+% permite darle una definición arbitraria.
+%
+% \begin{decl}
+% \con  |es-nodecimaldot|\opp
+% \end{decl}
+%
+% Cancela por completo el mecanismo del punto decimal.
+%
+% \subsection{División de palabras}
+%
+% \textsf{Spanish} comprueba la 
+% codificación en el momento en que se usa un acento: si la 
+% codificación es |OT1| se toman medidas para facilitar
+% la división, que pese a todo nunca será perfecta, mientras que con 
+% |T1| se accede directamente al carácter correspondiente.
+%
+% \begin{decl}
+% \txt  |"-    "=    "~|\act{shorthands}
+% \deact{\textit{es-noshorthands, es-sloppy}}
+% \end{decl}
+%
+% Para matizar la división de palabras hay cuatro posibilidades, dos 
+% de ellas con el método de abreviaciones:
+% \begin{itemize}
+% \item la orden |\-| es un guión opcional que no permite
+% más divisiones, 
+%
+% \item |"-| es similar pero permite más divisiones,
+%
+% \item un |-| es un guión que no permite más divisiones ni
+% antes ni después, y
+% 
+% \item |"=| es el equivalente que sí las permite,\footnote{No
+% es una buena idea usar esta orden, pero en 
+% medidas muy cortas puede resultar necesario.}
+%
+% \end{itemize}
+% Por ejemplo (con las posibles divisiones marcadas con \hmk):
+% \begin{quote}\small\begin{tabbing}
+% |Zaragoza-Barcelona|\qquad \= Zaragoza-\hmk Barcelona\\
+% |Zaragoza"=Barcelona| \>
+%    Za\hmk ra\hmk go\hmk za-\hmk Bar\hmk ce\hmk lo\hmk na\\
+% |semi\-abierto| \> semi\hmk abierto\\
+% |semi"-abierto| \> se\hmk mi\hmk abier\hmk to.\footnotemark
+% \end{tabbing}\footnotetext{Justo antes y después de
+% {\ttfamily\string"\string-} y {\ttfamily\string"\string=} se
+% aplican los correspondientes
+% valores de {\ttfamily\string\...hyphenmin} lo que implica que la
+% divisón semia\hmk bierto no es posible.
+% éste es un comportamiento correcto.}
+% \end{quote}
+%
+% La abreviación |"~| se usa cuando se quiere que el guión
+% también aparezca al comienzo de la siguiente línea. Por ejemplo:
+% \begin{quote}\small\begin{tabbing}
+% |infra"~rojo|  \quad \= in\hmk fra-ro\hmk jo, pero infra-\hmk-rojo.
+% \end{tabbing}\end{quote}
+%
+% \begin{decl}
+%\txt  |"+  "+-  "+--|\act{shorthands}\deact{\emph{no-shorthands, 
+% es-sloppy}}
+% \end{decl}
+%\vskip-1.5pc\vskip0pt
+% \begin{decl}
+% \txt  |~-  ~--  ~---|\act{shorthands}\deact{es-notilde, \emph{no-shorthands, 
+% es-minimal, es-sloppy}}
+% \end{decl}
+
+% Evitan divisiones: |~-|, que resulta útil para expresar una serie
+% de números sin que el guión los divida (12~-14, |12~-14|), y
+% |~---|, que es la forma que debe usarse para abrir incisos con
+% rayas, ya que de lo contrario puede haber una división entre la
+% raya de abrir y la palabra que le sigue:
+% \begin{quote}\small\begin{tabbing}
+%|Los conciertos ~---o % academias--- que organizó...|
+% \end{tabbing}\end{quote}
+%
+% También pueden emplearse para esta misma función las abreviaciones
+% |"+|, |"+-| y |"+---|.  Mientras que este guión evita toda posible
+% división en los elementos que une, la raya (---) y la semirraya
+% (--) las permiten en las palabras que le precedan o le sigan.
+% 
+% Otra abreviación es |"rr| que sirve para el 
+% único cambio de escritura del castellano en caso de haber división.  
+% La \lsc{RAE} indica que al añadir un prefijo que termina en vocal a 
+% una palabra que comienza con \emph{r}, ésta última debe 
+% doblarse a menos que se unan por un guión. Por ejemplo:
+% \begin{quote}\small\begin{tabbing}
+% |extra"rradio|  \quad \= ex\hmk trarra\hmk dio, pero extra-\hmk 
+%    radio.
+% \end{tabbing}\end{quote}
+% No hay acuerdo sobre si esta regla y otras similares han de 
+% aplicarse o no, aunque la opinión mayoritaria actual está en
+% contra.
+%
+% \subsection{Otros}
+%
+% \begin{decl}
+% \txt  |"/|\act{shorthands}\deact{\textit{es-noshorthands, es-sloppy}}
+% \end{decl}
+%
+% Es una utilidad tipográfica más que específicamente española.
+% En ciertos tipos, como Times, el extremo inferior de la barra está
+% en la línea de base y expresiones como <<am/pm>> resultan poco
+% estéticas.  |"/| produce una barra que, de ser necesario, se baja
+% ligeramente.  Computer Modern tiene una barra bien diseñada y no es
+% posible ilustrar aquí este punto pero en todo caso se escribiría
+% |am"/pm|.\footnote{En \MEA{141} se recurre a una solución que es la
+% única sencilla en programas de maquetación: usar un cuerpo menor.
+% Pero con \TeX{} es mucho más fácil automatizar las tareas.}
+%
+% \begin{decl}
+% \txt  |"y|\act{shorthand}\deact{\textit{es-noshorthands, es-sloppy}}
+% \end{decl}
+%
+% El signo \textit{et tironiano}, que en español se empleó muy a
+% menudo, se puede <<imitar>> con |"y|, siempre que se haya cargado el
+% paquete |graphics|; de no ser así, se usa la letra $\tau$, aunque
+% la variante normal de \TeX{} no es demasiado apropiada.
+%
+% \section{Funciones de texto y matemáticas}
+%
+% \subsection{Abreviaturas}
+%
+% \begin{decl}
+% \txt  |\sptext|\marg{texto}\act{text}\deact{\textit{es-sloppy}}
+% \end{decl}
+%
+% Pone un punto y le sigue el argumento en voladitas.  Para
+% abreviaturas como |adm\sptext{ón}| que da adm\sptext{ón}.  Hay seis
+% abreviaciones asociadas a ordinales: |"a|, |"A|, |"o|, |"O|, |"er| y
+% |"ER| que equivalen a |\sptext{a}|, etc. Muchos tipos
+% añaden un pequeño subrayado que debe evitarse, y por tanto no se
+% deben escribir los ordinales con \textsf{inputenc}.
+%
+% Para ajustar el tamaño lo mejor posible, se usa el de
+% índices en curso. Esto funciona bien salvo para tamaños muy 
+% grandes o muy pequeños, donde los resultados son meramente
+% aceptables. 
+%
+% En Plain \TeX{} se ejecuta la orden |\sptextfont| para la
+% letra voladita, de forma que |{\bf\let\sptextfont\bf 1"o}| da el
+% resultado correcto (|\mit| si es para cursiva). Para usar un tipo
+% nuevo con |\sptext| hay que definir también las variantes 
+% matemáticas con |\newfam|.
+%
+% \subsection{Espaciado}
+% 
+% Salvo excepciones, el espaciado español difiere relativamente poco
+% del inglés; una de ellas es que en \textsf{spanish} |\frenchspacing|
+% está activo.
+% 
+% \begin{decl}
+% \txt  |\...|\act{text}\deact{\textit{es-sloppy}}
+% \end{decl}
+%
+% Puntos suspensivos menos espaciados que  |\dots|. El espacio 
+% que sigue se conserva:
+% \begin{quote}\small\begin{tabbing}
+% |\... y solo estaba\... ella.|\quad\=\... y solo estaba\... ella.
+% \end{tabbing}\end{quote}
+% También podrían escribirse los tres puntos sin más |...|, y en
+% la práctica no hay diferencia, a menos que se cambie el
+% valor del espacio tras punto; en ese caso, la forma con barra
+% da los valores apropiados \emph{dentro} de una sentencia, y
+% los tres puntos \emph{al final} de ella. Esta orden no 
+% interfiere con el valor original de |\.| (un punto suprascrito).
+%
+% \begin{decl}
+% \txt  |\%|\act{text}\deact{\textit{es-minimal, es-sloppy}}
+% \end{decl}
+%
+% Se añade un espacio fino antes del signo (que
+% más exactamente es |\,|, con lo cual se puede "<recuperar"> con
+% su opuesto |\!| si |\%| no sigue a una cifra; también se puede 
+% emplear |\percentsign|).
+%
+% \begin{decl}
+% \con  |\spanishplainpercent|
+% \end{decl}
+%
+% Orden para que  |\%| no añada el espacio fino. Puede ser útil 
+% en cuadros, si  |\%| aparece siempre entre paréntesis.
+%
+% \subsection{Fuentes}
+%
+% \begin{decl}
+% \txt  |\lsc|\marg{texto}\act{text}\deact{\textit{es-sloppy}}
+% \end{decl}
+%
+% Pasa \textit{texto} a versalitas:
+% \begin{quote}\small\begin{tabbing}
+% |\lsc{RAE}| \quad \= \lsc{RAE}\\
+% |\lsc{ReNFe}| \quad \= \lsc{ReNFe}.\\
+% |siglo \lsc{XVII}| \quad \= siglo \lsc{XVII}\\
+% |capítulo \lsc{II}| \quad \= capítulo \lsc{II}.
+% \end{tabbing}\end{quote}
+% 
+% Para evitar que con un tipo que carece de versalitas acabe
+% apareciendo (por substitución) un texto de minúsculas se intenta
+% usar en estos casos las versales \emph{reales} de un tamaño menor
+% (\LaTeX\ tiende a sustituir versalitas por versalitas, pero hay
+% excepciones, como con las negritas).
+% 
+% \begin{decl}
+% \txt  |\í|\alw
+% \end{decl}
+%
+% Lo mismo que  |í|.
+%
+% \subsection{Entrecomillados}
+% 
+% \begin{decl}
+% \txt  |\begin{quoting} ... \end{quoting}|\alw
+% \end{decl}
+%
+% El entorno |quoting| entrecomilla un  
+% texto, añadiendo comillas de seguir al comienzo de 
+% cada párrafo en su interior.\footnote{Se puede encontrar
+% una detallada exposición de las comillas en \DTL{44 ss.} De ahí
+% se ha tomado algún ejemplo.}
+%
+% \begin{decl}
+% \txt  |<<    >>|\act{shorthands}\deact{es-noquoting, \textit{es-noshorthands, es-minimal, 
+% es-sloppy}}
+% \end{decl}
+%\vskip-1.5pc\vskip0pt
+% \begin{decl}
+% \txt  |"`    "'|\act{shorthands}\deact{\textit{es-noshorthands, es-sloppy}}
+% \end{decl}
+%
+% También se pueden emplear las abreviaciones |<<| y |>>| (o
+% alternativamente |"`| y |"'|) que se limitan a llamar a |quoting|,
+% que por ser entorno considera sus cambios internos como locales.
+% (Es decir, |<< ...  >>| implica |{<< ...  >>}|.)  Las abreviaciones
+% |"<| y |">| continúan dando sin más los caracteres de comillas de
+% abrir y cerrar, respectivamente.
+% 
+% Por ejemplo:
+%\begin{verbatim}
+% <<Se llaman <<comillas de seguir>> a las que son de cierre,
+% pero se colocan al comienzo de cada párrafo cuando se transcribe
+% un texto entrecomillado con más de un párrafo.
+% 
+% En su interior, como de costumbre, se usan inglesas.>>
+%\end{verbatim}
+% cuyo resultado es:
+% \begin{quotation}\small
+% <<Se llaman <<comillas de seguir>> a las que son de cierre,
+% pero se colocan al comienzo de cada párrafo cuando se transcribe
+% un texto entrecomillado con más de un párrafo.
+% 
+% En su interior, como de costumbre, se usan inglesas.>>
+% \end{quotation}
+%
+% También se añaden comillas de seguir en listas, excepto con la
+% opción \texttt{es-nolists} o cualquier otra que las desactive.
+% 
+% Este entorno se puede redefinir, como por ejemplo:
+%\begin{verbatim}
+% \renewenvironment{quoting}{\itshape}{}
+%\end{verbatim}
+% pero en principio no implica un nuevo párrafo, ya que 
+% está pensado para ser usado también en el texto.
+%
+% \begin{decl}
+% \con  |\lquoti| |\rquoti| |\lquotii| |\rquotii| |\lquotiii| 
+% |\rquotiii|
+% \end{decl}
+% 
+% Controlan las comillas en |quoting|, según el
+% nivel en que nos encontremos. |\lquoti| son las comillas de abrir
+% más exteriores, |\lquotii| las de segundo nivel, etc., y lo mismo
+% para las de cerrar con |\rquoti|... Para las de seguir siempre se
+% usan las de cerrar. Los valores predefinidos están en el cuadro 3.
+% \begin{table}
+% \center\small
+% \caption{Entrecomillados}
+% \vspace{1.5ex}
+% \begin{tabular}{l@{\hspace{5em}}l}

+% \botrule2
+% \end{tabular}
+% \end{table}
+% 
+% \begin{decl}
+% \con  |\activatequoting    \deactivatequoting|
+% \end{decl}
+% 
+% Las incompatibilidades potenciales de estas abreviaciones son
+% enormes. Por ejemplo, en \textsf{ifthen} se cancelan las
+% comparaciones entre números;\,\footnote{Y en \texttt{\textbackslash 
+% ifnum},
+% \texttt{\textbackslash ifdim}, etc., usado por los desarrolladores en
+% los paquetes.} también
+% resultan inoperantes |@>>>| y |@<<<| de
+% \textsf{amstex}.\footnote{Aunque en 
+% este caso cabe usar los sinónimos |@)))| y |@(((|.}
+% Por ello, se da la posibilidad de cancelarlas y reactivarlas con
+% estas órdenes, aunque si se está usando 
+% \textsf{xmltex} ya se
+% desactivan por completo de forma automática. El entorno
+% |quoting| siempre permanece disponible.\footnote{Algunos tipos
+% disponen de esta ligadura de forma interna para
+% generar los caracteres de comillas, por lo que en ellos también
+% podemos usarlos siempre, aunque los ajustes proporcionados por
+% \textsf{spanish} se pueden perder; por otra parte, tampoco se
+% usan demasiado a menudo.}
+% 
+% \subsection{Funciones matemáticas}
+%
+% \begin{decl}
+% \txt |\lim \limsup \liminf \bmod \pmod \sen \tg| 
+% etc.\act{math}\deact{\textit{es-minimal, es-sloppy}}
+% \end{decl}
+%
+% Tradicionalmente, las abreviaciones de lo que en \TeX\ se conocen
+% como operadores se han formado a partir del nombre castellano, lo
+% que implica la presencia del acento en lím (en sus tres formas
+% |\lim|, |\limsup| y |\liminf|), máx, mín, ínf y mód (en sus dos
+% formas |\bmod| y |\pmod|).
+%
+% Con \textsf{spanish} pueden seguirse varias convenciones con ayuda
+% de las siguientes órdenes:
+% \begin{decl} \con  |\accentedoperators| |\unaccentedoperators|
+% \end{decl}
+% Activa o desactiva los acentos.
+% Por omisión se acentúan, como por ejemplo: $\lim_{x\to 0}(1/x)$
+% (|$\lim_{x\to 0}(1/x)$|).
+% 
+% \begin{decl}
+% \con  |\spacedoperators| |\unspacedoperators|
+% \end{decl}
+% Activa o desactiva el espacio entre "<arc"> y la función.
+% Lo habitual ha sido con espacio; así pues, por omisión
+% se espacia.
+%
+% También se añaden |\sen|, |\arcsen|, |\tg| y |\arctg|,
+% que dan las funciones respectivas.
+% \begin{decl}
+% \con  |\spanishoperators|
+% \end{decl}
+%
+% Otras funciones trigonométricas se encuentran almacenadas en el
+% parámetro |\spanishoperators|, que inicialmente incluye cotg,
+% cosec, senh y tgh.  La razón por la que estas funciones se han
+% separado es porque su forma no está normalizada en el ámbito
+% hispanohablante.  De esta forma se puede cambiar por otras con, por
+% ejemplo:
+%\begin{verbatim}
+% \renewcommand{\spanishoperators}{ctg arc\,ctg sh ch th}
+%\end{verbatim}
+% (separadas con espacio). Cuando se selecciona \textsf{spanish} se crean
+% órdenes con esos nombres
+% y que dan esas funciones (siempre con |\nolimits|). Además de
+% las letras sin acentuar se aceptan las órdenes |\,| y |\acute|, que
+% se pasan por alto para formar el nombre. Por ejemplo, |arc\,ctg|
+% se escribe en el documento con
+% |\arcctg|, |M\acute{a}x| como |\Max| y |cr\acute{i}t| como |\crit|
+% (hay que usar |i| y no |\dotlessi|).
+% La orden |\,| responde a |\|(|un|)|spacedoperators|, y |\acute|
+% a |\|(|un|)|accentedoperators|.
+% 
+% Conviene que |\spanishoperators| esté en el preámbulo del
+% documento en sí, antes de |\selectspanish| o de 
+% |\begin{document}|.
+%
+% \begin{decl}
+% \txt  |\dotlessi|\act{math}\deact{\textit{es-sloppy}}
+% \end{decl}
+% 
+% La \textit{i} sin punto también es accesible directamente en modo
+% matemático con la orden |\dotlessi|, de forma que se puede escribir
+% |\acute{\dotlessi}|.  Por ejemplo,
+% |$V_{\mathbf{cr\acute{\dotlessi}t}}$| da
+% $V_{\mathbf{cr\acute{\dotlessi}t}}$.
+%
+%
+% \section{Opciones generales}
+%
+% Están pensadas principalmente para documentos basados en una clase
+% o un estilo editorial muy preciso que no debe tocarse. Para conocer 
+% los cambios exactos, véanse las diferentes entradas que describen 
+% las funciones de \textsf{spanish}.
+%
+% \begin{decl}
+% \con  |es-minimal|\opp
+% \end{decl}
+%
+% Anula la mayoría de los cambios pero deja unas cuantas utilidades
+% que pueden resultar utiles en el momento de escribir el texto. 
+% 
+% \begin{decl}
+% \con  |es-sloppy|\opp
+% \end{decl}
+% 
+% Anula, además, todas las ligaduras sin excepción, la eñe en listas y los 
+% grupos \textsf{text} y \textsf{math}.
+%
+% \section{Selección}
+%
+% \begin{decl}
+% |\selectspanish|
+% \end{decl}
+% 
+% Por omisión, \babel{} deja <<dormidas>> las lenguas hasta que se
+% llega a |\begin{document}| con el fin de evitar conflictos por
+% las abreviaciones; a cambio,
+% se priva de la posibilidad de usar las lenguas en el preámbulo 
+% en órdenes como |\savebox|, |\title|, |\newtheorem|, etc.
+% 
+% La orden |\selectspanish| permite activar \textsf{spanish} con sus
+% extensiones y abreviaciones  antes de
+% |\begin{document}|.\footnote{Algunos detalles, que
+% apenas afectan a \textsf{spanish}, siguen sin activarse hasta el
+% comienzo del documento.}
+% De esta forma, podríamos decir
+%\begin{verbatim}
+% \documentclass{book}
+% \usepackage[T1]{fontenc}
+% \usepackage[cp1252]{inputenc}
+% \usepackage[spanish,activeacute,es-notilde]{babel}
+% ... % Mas paquetes
+% 
+% \selectspanish
+% 
+% \title{Título}
+% \author{Autor}
+% \newcommand{\pste}{para"-psicológicamente}
+% ...   % Mas definiciones
+%
+% \begin{document}
+%\end{verbatim}
+%
+% \section{Adaptación}
+%
+% \subsection{Opciones por países}
+% \label{paises}
+%
+% % \begin{decl} \con |mexico| \quad |mexico-com|
+% \end{decl}
+%
+% La primera cambia \textit{cuadro} a \textit{tabla} y desactiva tanto
+%  |<||<>||>| como el punto decimal.  También cambia
+%  |"`| y  |"'| a ``\,`\,"<\,">\,'\,''. Es decir, aparte de
+% redefinir las comillas, equivale a:
+% a:
+%\begin{verbatim}
+%\usepackage[spanish,es-nodecimaldot,es-tabla,es-noquoting]{spanish}
+%\end{verbatim}
+% La segunda es similar
+% pero sí activa el punto decimal.  (Obsérvese que no van precedidas
+% de  |es-|.)
+%
+% Probablemente, esta opción también sea apropiada en algunos
+% países de América Central y del Sur.
+%
+% \subsection{Configuración}
+%
+% En sus últimas versiones, \babel{} ofrece la posibilidad
+% de cargar automáticamente un archivo con el mismo nombre que
+% el principal, pero con extensión |.cfg|. \textsf{Spanish}
+% proporciona unas pocas órdenes para ser usadas en este archivo:
+%
+% \begin{decl}
+% \con |\es@activeacute|
+% \end{decl}
+% Activa las abreviaciones con apóstrofos, sin que sea
+% necesario incluir |activeacute| como opción en |\usepackage|.
+%
+% \begin{decl} \con  |\es@enumerate{<leveli>}|%
+%      |{<levelii>}{<leveliii>}{<leveliv>}|\alw
+% \end{decl} 
+% Cambia los valores preestablecidos por \textsf{spanish} para
+% |enumerate|. \textit{leveln} consiste en una letra, que
+% indica qué formato tendrá el número, seguida
+% de cualquier texto. La letra tiene que ser: |1| (arábigo),
+% |a| (minúscula \emph{cursiva}\,\footnote{La letra es cursiva
+% pero no los signos que le puedan seguir. Más bien debería
+% decirse destacada, ya que se usa |\string\emph|.
+%  Véase \DTL{11}.}), |A| (versal),
+% |i| (romano \emph{versalita}), |I| (romano versal) o
+% finalmente |o| (ordinal\,\footnote{Lo normal es no añadir ningún 
+% signo tras ordinal.}).
+%
+% Esta orden no está pensada para hacer cambios elaborados, sino
+% sólo meros reajustes. Los valores preestablecidos 
+% equivalen a
+%\begin{verbatim}
+% \es@enumerate{1.}{a)}{1)}{a$'$)}
+%\end{verbatim}
+%
+% \begin{decl} \con  |\es@itemize{<leveli>}|%
+%      |{<levelii>}{<leveliii>}{<leveliv>}|\alw
+% \end{decl} 
+% Lo mismo para |itemize|, sólo que los argumentos se
+% usan de forma literal. Los valores originales de \LaTeX{} son
+% similares a
+%\begin{verbatim}
+% \es@itemize{\textbullet}{\normalfont\bfseries\textendash}
+%    {\textasteriskcentered}{\textperiodcentered}
+%\end{verbatim}
+%
+% \begin{decl}\con |\es@operators|\act{math}
+% \end{decl}
+% Todo lo relativo a operadores se cancela con
+%\begin{verbatim}
+% \let\es@operators\relax
+%\end{verbatim}
+% Es buena idea incluirlo si no se van a usar, ya que ahorra memoria.
+%
+% Otros ajustes útiles en este contexto son |\spanishoperators|,
+% |\selectspanish| y |\deactivatequoting|.
+%
+%
+% Recordemos que todos los cambios
+% operados desde este archivo restan compatibilidad al
+% documento, por lo que si se distribuye conviene adjuntarlo
+% con el entorno |filecontents|.
+%
+% \subsection{Pasar opciones desde un paquete o clase}
+%
+% \begin{decl} \con  |\spanishoptions|
+% \end{decl}
+%
+% Como  |\PassOptionsToPackage| añade opciones al comienzo y
+% las opciones específicas de \textsf{spanish} han de ir al final, definiendo
+% esta macro se puede controlar el comportamiento de \textsf{spanish} antes
+% de su carga.
+%
+% \subsection{Otros cambios}
+%
+% Las adaptaciones se encuentran organizadas en varios grupos, a los 
+% que corresponden sendas macros: 
+% |\textspanish|, |\mathspanish|,
+% |\shorthandsspanish|, |\datespanish| y |\captionsspanish|.  Pueden
+% cancelarse con:
+%\begin{verbatim}
+%  \renewcommand\textspanish{}
+%\end{verbatim}
+%
+% \section{Plain \TeX}
+% 
+% Con Plain hay que hacer:
+%\begin{verbatim}
+% \input spanish.sty
+%\end{verbatim}
+% 
+% Se incluyen: traducciones, casi todas las abreviaciones, coma
+% decimal, utilidades para división de palabras, ordinales en una
+% versión simplificada (y no muy elegante), funciones matemáticas,
+% |\í| y espaciado.  La selección de la lengua es inmediata al
+% cargar el archivo.
+% 
+% En cambio no están disponibles: entrecomillados, 
+% |\lsc| ni las adaptaciones de lengua principal.
+%
+% \section{Compatibilidad con versiones anteriores}
+%
+% En versiones de \textsf{babel} bastante antiguas, las abreviaciones 
+% con |'| se activaban por omisión, mientras que ahora es necesario
+% |activeacute|.
+%
+% En la versión 4, la abreviación |~n| se consideró para extinguir.
+% En la versión 5 sigue estando, pero \textit{no} se activa por
+% omisión, sino que hay que emplear |es-tilden|.
+%
+% En la versión 5 el grupo \textsf{layout} no se retrasa a
+% |\begin{document}|, como en la 4, sino que se ejecuta

+%
+% \section{The Spanish language}
+%
+% The file \file{\filename}\footnote{The file described in this
+% section has version number \fileversion\ and was last revised on
+% \filedate.  The maintainer from v4.0 on is Javier Bezos
+% (http://www.tex-tipografia.com).  Previous
+% versions were made by Julio S\'anchez.  The English documentation
+% has been improved by José Luis Rivera; thanks to him it is now a lot
+% clearer.} defines all the language-specific macros for the Spanish
+% language.
+%
+% Spanish support is implemented following mainly the guidelines given
+% by Jos\'e Mart\'\i nez de Sousa.  You may get the the full
+% documentation (more comprehensive, but regrettably only in Spanish)
+% by typesetting |spanish.dtx| directly.  There are examples and some
+% additional features documented in the Spanish version only.
+% Cross-references in this section point to that document.
+% 
+% \paragraph{Features} This style provides:
+%
+% \begin{itemize}
+% \item Translations following the International \LaTeX{} 
+% conventions, as well as |\today|.
+% 
+% \item Shorthands listed in Table~\ref{tab:spanish-quote-def}.
+% Examples in subsection~3.4 are illustrative.  Notice that |"~| has a
+% special meaning in \textsf{spanish} different to other languages,
+% and is used mainly in linguistic contexts.
+% 
+% \begin{table}[htb]
+% \centering
+% \begin{tabular}{lp{8cm}}
+% |'a|      & Acute accented a. Works for e, i, o, u, too (both
+%             lowercase and uppercase).\\
+% |'n|      & \~n (uppercase too).\\
+% |"i|      & \"i (uppercase too).\\
+% |"u|      & \"u (uppercase too).\\
+% |"a| |"o| & Ordinal numbers (uppercase |"A|, |"O| too).\\
+% |"er "ER| & Ordinal 1.\textsuperscript{er} 1.\textsuperscript{\textsc{er}}\\
+% |"c|      & \c{c} (uppercase too).\\
+% |"rr|     & rr, but -r when hyphenated.\\
+% |"y|      & An old ligature for ``et'' (like the English \&).\\
+% |"-|      & Like |\-|, but allowing hyphenation in the rest 
+%             the word.\\
+% |"=|      & Like |-|, but allowing hyphenation in the rest 
+%             the word.\\
+% |"~|      & The hyphen is repeated at the very beginning of 
+%             the next line if the word is hyphenated at this
+%             point.\\
+% |""|      & Like |"-| but producing no hyphen sign.\\
+% |~-|      & Like |"-| but with no break after the hyphen. Works for
+%             en-dashes (|~--|) and em-dashes (|~---|). |"+|, |"+-| 
+%             and |"+--| are synonymous.\\
+% |"/|      & A slash slightly lowered, if necessary.\\
+% \verb+"|+ & Disable ligatures at this point.\\
+% |"<|      & Left guillemets.\\
+% |">|      & Right guillemets.\\
+% |<<| |>>| & |\begin{quoting}| and |\end{quoting}|. (See below.) 
+%             |"`| and |"'| are synonymous.\\
+% |"? "!|   & Opening question and exlamation marks (?`!`) 
+%             aligned on the baseline, useful for all-caps headings, etc.
+% \end{tabular}
+% \caption{Extra definitions made by file \file{spanish.ldf}}
+% \label{tab:spanish-quote-def}
+% \end{table}
+% 
+% \item |\frenchspacing|.
+%
+% \item \emph{In math mode}, a dot followed by a digit is replaced
+% by a decimal comma.
+% 
+% \item Spanish ordinals and abbreviations with the |\sptext|\marg{text}
+% command as, for instance, |1\sptext{er}|. The preceptive dot is included.
+% 
+% \item Accented (l\'\i m, m\'ax, m\'\i n, m\'od) and spaced
+% (arc\,cos, etc.) functions. 
+%
+% \item |\dotlessi| is provided for use in math mode.
+%
+% \item A |quoting| environment and a related pair of shorthands |<<|
+% and |>>|. Useful for traditional spanish multi-paragraph quoting.
+%
+% \item There is a small space before the percent |\%| sign.
+% 
+% \item |\lsc| provides lowercase small caps. (See subsection~3.10.)
+%
+% \item Ellipsis is best typed as |...| or, within a sentence, as |\...|
+% 
+% \end{itemize}
+% 
+% If \textsf{spanish} is the main language, the command 
+% |\layoutspanish| is added to the main group, modifying the standard
+% classes throughout the whole document in the following way:
+%
+% \begin{itemize}
+%
+% \item Paragraphs are set with |\indentfirst|.
+% 
+% \item Both |enumerate| and |itemize| are adapted to Spanish rules.
+% 
+% \item Both |\alph| and |\Alph| include \textit{\~n} after \textit{n}.
+% 
+% \item Symbol footmarks are one, two, three, etc., asterisks.
+% 
+% \item |OT1| guillemets are generated with two |lasy| symbols instead
+% of small |\ll| and |\gg|.
+% 
+% \item |\roman| is redefined to write small caps Roman numerals, since
+% lowercase Roman numerals are discouraged (see below).
+% 
+% \item There is a dot after section numbers in titles, headings, and toc.
+%
+% \end{itemize}
+%
+% A subset of these features is implemented for Plain \TeX{}
+% (accesible with the command |\input spanish.sty|).  Most
+% significantly, |\lsc|, the |quoting| environment, and features
+% provided by |\layoutspanish| are missing.
+%
+% \paragraph{Customization}
+%
+% Beginning with version 5.0, customization is made following two paths:
+% via |options| or via |commands|; these options and commands override 
+% the layout for Spanish documents at different levels: options are meant for 
+% use at the preamble only, while commands may be used in the configuration
+% file or at document level.
+%
+% Global options control the overall appearance of the document, and may 
+% be set on the |{babel}| call, right after calling |spanish|, or 
+% shortly before the call to |{babel}|, to ensure their proper loading
+% at runtime. Thus, the following calls are roughly equivalent:
+% 
+% \begin{verbatim}
+% \usepackage[...,spanish,es-nosectiondot,es-nodecimaldot,...]{babel}
+% 
+% \def\spanishoptions{es-nosectiondot,es-nodecimaldot}
+% \usepackage[...,spanish,...]{babel}
+% \end{verbatim}
+%
+% \begin{table}
+% \centering
+% \begin{tabular}{cccc}\hline
+%  Basic Options       & |es-minimal| & |es-sloppy| & |es-noshorthands| \\\hline
+%  |es-noindentfirst|  & X  & X  &   \\
+%  |es-nosectiondot|   & X  & X  &   \\
+%  |es-nolists|        & X  & X  &   \\
+%  |es-noquoting|      & X  & X  & X \\
+%  |es-notilde|        & X  & X  & X \\
+%  |es-nodecimaldot|   & X  & X  & X \\
+%  |es-nolayout|       &    & X  &   \\
+%  |es-ucroman|        & X  &    &   \\
+%  |es-lcroman|        & X  & X  &   \\\hline
+% \end{tabular}
+%  \caption{Spanish Customization Options}
+%  \label{tab:SpanishCustomizationOptions}
+% \end{table}
+%
+% Some global options are built upon lower level options, and may be
+% used as shorthand for more global customizations.
+% Table~\ref{tab:SpanishCustomizationOptions} gives an overview of the
+% global options constructed this way.  Most of these options are
+% self-explanatory: they disable the changes made to the basic \LaTeX\
+% layout by |spanish|.  |es-lcroman| however, and a few others, need a
+% bit of explanation, and they may be described as follows:
+%
+% \begin{itemize}
+%
+% \item Traditional Spanish typography discourages the use of
+% lowercase Roman numerals; instead, a smallcaps variant is
+% implemented.  However, since |Makeindex| seems to choke on the code
+% implementing lowercase Roman numerals (via the |\lsc| macro), two
+% workarounds are implemented: the |es-ucroman| option converts all
+% Roman numerals to uppercase, and the |es-lcroman| option turns all
+% Roman numerals to lowercase; the former should be preferred over the
+% latter.  Three macros control local changes to Roman numbers:
+% |\spanishscroman|, |\spanishucroman|, and |\spanishlcroman|.
+% 
+% \item The |es-preindex| option calls the |romanidx.sty| package
+% automatically to fix index entries in smallcaps roman form.  An
+% additional macro,
+% |\spanishindexchars|\marg{encap}\marg{openrange}\marg{closerange}
+% determines the characters delimiting index entries.  Defaults are
+% \verb=\spanishindexchars{|}{(}{)}=.
+%
+% \item The |es-tilden| option restores the old tilde |~| shorthand
+% for \~n.  This shorthand is however \emph{strongly} deprecated.
+%
+% \item The |es-nolayout| option disables layout changes in the
+% document when |spanish| is the main language.  These changes affect
+% enumerated and itemized lists, enumerations (alphabetic order
+% excludes \~n), and symbolic footnotes.
+%
+% \item The |es-noshorthands| disables the shorthand mechanism
+% completely: neither |"| nor |'| nor |<| nor |>| nor |~| nor |.| work
+% at all.
+%
+% \item The |es-noquoting| option disables the macros |<<| and |>>|
+% calling the |quoting| environment; the alternative macros |"`| and
+% |"'| are still available.
+%
+% \item The |es-uppernames| option makes uppercase versions of
+% captions for chapter, tablename, etc.
+%
+% \item The |es-tabla| option changes ``cuadro'' for ``tabla'' in
+% captions.
+%
+% \end{itemize}
+%
+% Finally, the Spanish 5 series begins the implementation of national
+% variations of Spanish typography, beginning with Mexico.  Thus the
+% global options |mexico| and |mexico-com| are adapted to practices
+% spread in Mexico, and perhaps Central America, the Caribbean, and
+% some countries in South America.\footnote{The main difference is
+% that |mexico| disables the |decimaldot| mechanism, while
+% |mexico-com| keeps it enabled; both change the |quoting|
+% environment, disabling the use of guillemets.}
+%
+% Many of the global options are implemented via macros, which may be
+% included in the configuration file |spanish.cfg|, in the preamble,
+% after the call to |babel|, and in the body of the document.  These
+% macros are the following.
+%
+% \begin{itemize}
+%
+% \item The macros |\spanishdashitems| and |\spanishsignitems| change
+% the values of itemized lists to a series of dashes or an alternative
+% series of symbols, respectively.
+%
+% \item The command |\deactivatequoting| deactivates the |<<| and |>>|
+% shorthands if you want to use |<| and |>| in numerical comparisons
+% and some AMS\TeX\ commands.
+% 
+% \item You may kill the space in spaced operators with
+% |\unspacedoperators|. 
+%
+% \item You may kill the accents on accented operators with 
+% |\unaccentedoperators|.  
+%
+% \item The command |\decimalpoint| resets the decimal separator to
+% its default (dot) value, while |\spanishdecimal|\marg{symbol} allows
+% for an arbitrary definition.
+%
+% \item |\spanishplainpercent| prevents the addition of a thinspace before 
+% the percent sign in texts. This might be useful for parenthesized percent
+% signs in tables, etc.
+%
+% \item The macros |\spanishdatedel| and |\spanishdatede| control the 
+% if the article is given in years (|del| or |de|). 
+%
+% \item The macro |\spanishreverseddate| sets the date of the format
+% ``Month Day del Year''.
+%
+% \item The macro |\Today| gives months in uppercase.
+%
+% \item The macros |\spanish|\textit{caption} change the value of the \emph{caption} 
+% automatically (no need to add an |\addto|).
+%
+% \item The command |\spanishdeactivate|\marg{characters} disables the
+% shorthand characters listed in the argument.  Elegible characters
+% are the set |.'"~<>|.  These shorthand characters may be globally
+% deactivated for Spanish adding this command to |\shorthandsspanish|.
+%
+% \item Extras are divided in groups controlled by the commands
+% |\textspanish|, |\mathspanish|, |\shorthandsspanish| y
+% |\layoutspanish|; their values may be cancelled typing
+% |\renewcommand|\marg{command}|{}|, or changed at will (check the
+% Spanish documentation or the code for details).
+% 
+% \item The command |\spanishoperators|\marg{operators} defines
+% command names for operators in Spanish.  There is no standard name
+% for some of them, so they may be created or changed at will.  For
+% instance, the command
+% |\renewcommand{\spanishoperators}{arc\,ctg m\acute{i}n}|
+% creates commands for these functions.  The command
+% |\,| adds thinspaces at the appropriate places for spaced operators
+% (like |\arcctg| in this case), and the command |\acute|\marg{letter}
+% adds an accent to the letter included in the definition (thus,
+% |m\acute{i}n| defines the accented function |\min| (m\'\i{}n);
+% please notice that |\dotlessi| is not necessary).
+% 
+% \item The commands
+% |\lquoti|\marg{string} |\rquoti|\marg{string} 
+% |\lquotii|\marg{string} |\rquotii|\marg{string} 
+% |\lquotiii|\marg{string} |\rquotiii|\marg{string} 
+% set the quoting signs in the |quoting| environment, 
+% nested from outside in. They may be |\renew|ed at will. 
+% Default values are shown in table~\ref{tab:spanish-quote-ref}.
+% \begin{table}
+% \center\small
+% \vspace{1.5ex}
+% \begin{tabular}{l@{\hspace{5em}}l}
+% |\lquoti|   &|"<|\\
+% |\rquoti|   &|">|\\
+% |\lquotii|  &|``|\\
+% |\rquotii|  &|''|\\
+% |\lquotiii| &|`|\\
+% |\rquotiii| &|'|
+% \end{tabular}
+% \caption{Default quoting signs set for the \texttt{quoting} environment.}
+% \label{tab:spanish-quote-ref}
+% \end{table}
+%
+% \item The command |\selectspanish*| is obsolete: if |spanish| is the
+% main language, all its features are available right after loading
+% |babel|.  The |es-delayed| option is provided to restore the
+% previous behavior and macros for backwards compatibility.
