+%\begin{abstract}
+%This document describes the package \textsf{esdiff} that makes
+%writing derivatives very easy.
+%It allows to write derivatives, partial derivatives, multiple
+%derivatives.
+%Some typographic options are available.
+%The macro about crossed derivatives was given on
+%\texttt{comp.text.tex} by Peter Schmitt.
+%\end{abstract}
+%\section{Derivatives}
+%
+%\DescribeMacro{\diff}
+%
+%Derivatives are obtained with the command \textsf{diff}.
+%
+%To get $\diff{f}{x}$, just write |$\diff{f}{x}$|.
+%
+%The ordre of the derivative can be set in square brackets.
+%So |$\diff[n]{f}{x}$| gives $\diff[n]{f}{x}$.
+%
+%\DescribeMacro{\diff*}
+%
+%It's easy to precise the point where the derivative is calculated:
+%
+% |$\diff*{f}{x}{x_0}$|
+%gives $\diff*{f}{x}{x_0}$.
+%
+%Of course, those two options can be used together:
+%|$\diff*[2]{g}{y}{0}$| gives as expected $\diff*[2]{g}{y}{0}$.
+%
+%\section{Partial derivatives}
+%
+%\DescribeMacro{\diffp}
+%
+%Partial derivatives are obtained with the macro
+%\textsf{diffp}, using the same syntaxe as with \textsf{diff}:
+%a star version to put a subscript, and square brackets to set
+%the order of the derivative according to only one variable.
+%
+%To get $\diffp{f}{x}$, just write
+%|$\diffp{f}{x}$|.
+%
+%We obtain $\diffp[2]{f}{x}$ writing |$\diffp[2]{f}{x}$|.
+%
+%\DescribeMacro{\diffp*}
+%
+%The notation $\diffp*{p}{V}{T}$ is the result of
+%|$\diffp*{p}{V}{T}$|.
+%
+%The notation of crossed derivatives is automatic.
+%To get $\diffp{f}{{x}{y^2}}$, write
+%
+%|$\diffp{f}{{x}{y^2}}$|.
+%This method can be used to write a partial derivative, without
+%square beackets. So |$\diffp{f}{{x^2}}$| gives $\diffp{f}{{x^2}}$.
+%
+%We can mix options:
+% |$\diffp*{f}{{x^2}{y^3}}{z}$|
+%gives $\diffp*{f}{{x^2}{y^3}}{z}$.
+%
+%\section{Options}
+%
+%Several options are available:
+%\begin{itemize}
+%\item
+%by default, derivatives are written in displaystyle on text mode.
+%The \textsf{display} option set this default. With the \textsf{text}
+%option, derivatives are written in textstyle on text mode;
+%\item
+%by default, the \texttt{d} of the derivative is written in roman.
+%Available options are \textsf{roman} and \textsf{italic};
+%\item
+%we can set the space between the \texttt{d} and the symbol of the
+%function or of the variable. By default, this space is null.
+%Available options are \textsf{thin}, \textsf{med} and
+%\textsf{big}. It may be fine to add a space when the \texttt{d}
+%is in italic;
+%\item
+%We can set the space between the $\partial$ and the symbol of the
+%function or of the variable. By default, this space is null.
+%Available options are \textsf{thinp}, \textsf{medp} and
+%\textsf{bigp};
+%\item
+%the space between $\partial x$ and $\partial y$ in crossed derivatives may be too
+%narrow. It is null by default. Available options are
+%\textsf{thinc}, \textsf{medc} and \textsf{bigc};
+%\end{itemize}
