+\begin{document}
+
+\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 dramaticaly 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}
+

+\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{cañón}
+\end{verbatim}
+is equivalent to
+\begin{verbatim}
+\index{can^^ffon@cañón}
+\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}
+
+This package fixes some babel annoyances. With it, you can decide
+which shorthands are used or even cancel the mechanism altogether. 
+You can prevent config files to be loaded, and citation and cross 
+reference macros to be redefined, too.
+
+\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{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.

+en lugar de con los caracteres reales.  En este 'ultimo caso, el paquete
+utiliza ciertas 'ordenes internas de \textsf{babel} por lo que no
+puedo garantizar su funcionamiento correcto con versiones distintas a
+las 3.6 a 3.8.  En caso de que \textsf{esindex} sea incompatible con
+futuras versiones de \textsf{babel} intentar'e adaptarlo en el menor
+tiempo posible.
+
+Salvo el car'acter \verb|actual| (normalmente \verb|@|) se pueden usar
+todos los caracteres especiales de \textit{MakeIndex}.  Se pueden usar
+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|$| en nuestro
+archivo \verb|.ist| particular, tendr'iamos que llamar al paquete del
+siguiente modo:
+\begin{verbatim}
+\usepackage[quote=$]{esindex}
+\end{verbatim}
+
+Es importante observar que, a diferencia de la opci'on para alem'an de
+\textit{MakeIndex}, el uso de \verb|"| en abreviaciones como \verb|"u|
+es completamente leg'itimo, ya que el paquete reconoce tal
+combinaci'on y la trata aparte.  Lo mismo vale para \verb|'| o
+\verb|~| en caso de que se usaran como car'acter 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 car'acter \verb|quote| ante \verb|encap| o
+\verb|level| no se detecta a menos que el grupo est'e encerrado entre
+llaves.  Por ejemplo, en lugar de \verb/\esindex{Pleca: "|}/ debe
+escribirse \verb/\esindex{Pleca: {"|}}/.  (En realidad en este caso
+podr'ia haberse usado \verb|\index|.  Es tan s'olo un ejemplo.)
+
+Aunque el hecho de que \verb|@| no se pueda usar en \verb|\esindex|
+hace que todav'ia algunas entradas se tengan que hacer <<a mano>>,
+la mayor parte del trabajo se ve considerablemente simplificado.
+
+Finalmente, hay que se'nalar que con este paquete no se crea en el 
+'indice una entrada propia para la palabras que empiezan por e'ne,
+sino que tan s'olo se a'naden al final de la ene. En el rar'isimo
+caso de que hubiera palabras que empiezan por e'ne habria que
+modificar el archivo \verb|.ind| a mano.
+
+% La versión 1.2 corrige la supresión incorrecta de acentos en los
+% primeros niveles si había más de uno.
+
+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}
+
+La versión 1.4 elimina un pequeño bicho con \verb|"U| y añade nuevas 
+funciones:
+\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|.

+
+\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}
+

+% Changes
+% ~~~~~~~
+%
+% 2006-05-12. TeX converts to ord any symbol with a math accent.
+% Accents now emulates this behaviour with braces around the
+% nucleous; otherwise, the original category is preserved and
+% the accents could look misaligned. (Reported by Viet-TrungLuu.)

+% Usage
+% ~~~~~
+%
+% This package modifies the definitions of \frontmatter and
+% \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, \pagenumbering has to be inside these macros -- most
+% of classes do that, but there are exceptions like memoir.
+%
+% To use it, just \usepackage{arabicfront}.

+% (\end occurred inside a group at level N)
+% 
+% This package replaces them with more useful messages
+% which show which environments (in reverse order) were

+% That's all. There are no user macros. Just use the package.

+% Usage
+% ~~~~~
+% This package defines two commands: \dotlessi and \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 \imath and 
+% \jmath; if a different font is used (like \mathrm, \mathbf, \mathsf) 
+% these commands look in the corresponding font tables to find their 
+% codes.  In text mode, they expand to \i and \j.  For example:
+%
+% $f_{\mathrm{m\acute{\dotlessj}n}}$

+% Usage
+% ~~~~~
+%
+% This is a tentative package aiming to provide a different approach
+% for multidocument works (mainly, books with a document per chapter).
+% Unlike the \include mechanism, every subdocument is a complete LaTeX
+% document and can be typeset separately.  What the package does is
+% sharing the aux files.  It's still an alpha version, and no attempt
+% has been done yet to make it to work with, say, 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 driver tex file containing a \subdocuments command
+% listing the files. With an optional argument you can set
+% its behaviour:
+% 
+% \subdocuments[clear=double]{file1, file2, file3}
+%
+% The option clear=double adds an empty page at the end to give a even
+% number of pages.  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 keyval package, so names containing = 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:
+%
+% \usepackage[master]{subdocs}
+%
+% where master is the name of the file described above.
+%
+% Since every subdocument reads all the aux files, \tableofcontents
+% may be used where desired.
