%\title{Typesetting vectors with beautiful arrow with \LaTeXe{}}
%\author{Eddie Saudrais}
%\date{version 1.2 07/092000}
%\maketitle
%\MakeShortVerb{\|}
%\begin{abstract}
%The package \textsf{esvect.sty} allows typesetting vectors.
%Several arrows are available.
%\end{abstract}
%\section{Installation}
%Run \LaTeXe{} on esvect.ins to generate files:
%\begin{enumerate}
%\item
%Put \textsf{esvect.sty} on TEXINPUT.
%\item
%Put \textsf{uesvect.fd} on TEXINPUT, for example with \textsf{esvect.sty}.
%\item
%Put \textsf{vect5.mf}, \textsf{vect6.mf}, \textsf{vect7.mf}, \textsf{vect8.mf},
%\textsf{vect9.mf} and \textsf{vect10.mf} on MFINPUT.
%\end{enumerate}
%
%Run METAFONT on *.mf file to generate *.tfm files. For example:
%
%\verb|mf \mode=localfont; input vect5.mf|
%
%Put \textsf{vect5.tfm}, ..., \textsf{vect10.tfm} on the right
%place.
%\section{Using esvect}
%Load the package with \verb|\usepackage{esvect}|, and enjoy!
%
%To obtain a vector, use the command \verb|\vv{arg}|.
%
%For example, \verb|$\vv{E$}|, \verb|$\vv{AB}$|,
%\verb|$\vv{\imath}$| and \verb|$\vv{u}$| give $\vv{E}$,
%$\vv{AB}$, $\vv{\imath}$ and $\vv{u}$.
%
%A star version \verb|\vv*{arg}{ind}| is available to typeset correctly a vector with a subscript:
%\verb|$\vv*{e}{r}$| and \verb|$\vv*{L}{\Delta}$| give $\vv*{e}{r}$
%and $\vv*{L}{\Delta}$.
%
%Height differents arrows are available. You have to select one
%using an option when you load the package:
%\verb|\usepackage[a]{esvect}|, ..., \verb|\usepackage[h]{esvect}|.
%The option \verb|d| is selected by default.
%
%Corresponding arrows are:
%
%\vskip1em
%\begin{tabular}{c c c c c c c c c}
%option &amp; a &amp; b &amp; c &amp; d &amp; e &amp; f &amp; g &amp; h \\
%fl\`eche &amp; $\fldrap$ &amp; $\fldrbp$ &amp; $\fldrcp$ &amp; $\fldrdp$ &amp; $\fldrep$
%&amp; $\fldrfp$ &amp; $\fldrgp$ &amp; $\fldrhp$\\
%\end{tabular}
%
%The size of the arrow is automatically calculated according to
%the math environment:
%
%\verb|$$\vv{E}_{\vv{u}_{\vv{u}}}}$$| gives
%$$\vv{E}_{\vv{u}_{\vv{u}}}$$
%
