\begin{abstract}{Brief description of the package:}
This package provides some new more flexible commands to typeset subscripts and superscripts in mathematical mode.
\end{abstract}


\artsection{Usage}
\artsubsection{Default lengths}
The following commands use the default lengths, as defined in \ref{lengths}. They are quite tight and are useful in case of an operator such as \Choice.
\begin{itemize}
\item \Verb[commandchars=-\[\]]+\fourscripts{-Choice}{-Boxast}{-Boxbox}{-Boxcircle}{-Boxbslash}+

Output: $\fourscripts{\choice}{\boxast}{\boxbox}{\boxcircle}{\boxbslash}$
\item \Verb[commandchars=-\[\]]+\lrsubscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\lrsubscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\lrsuperscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\lrsuperscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\twolscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\twolscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\tworscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\tworscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\lsubscript{-Choice}{-Boxbox}+

Output: $\lsubscript{\choice}{\boxbox}$
\item \Verb[commandchars=-\[\]]+\lsuperscript{-Choice}{-Boxbox}+

Output: $\lsuperscript{\choice}{\boxbox}$
\item \Verb[commandchars=-\[\]]+\rsubscript{-Choice}{-Boxbox}+

Output: $\rsubscript{\choice}{\boxbox}$
\item \Verb[commandchars=-\[\]]+\rsuperscript{-Choice}{-Boxbox}+

Output: $\rsuperscript{\choice}{\boxbox}$
\end{itemize}

\artsubsection{Larger skips}

\largerSkips

The following commands use larger lengths, as defined in \ref{lengths}: this is achieved by running the command \Verb+\largerSkips+. This is needed when we want to apply subscripts or superscripts to something larger than \Choice, such as {\renewcommand{\choice}{expression} \Choice.


\begin{itemize}
\item \Verb[commandchars=-\[\]]+\fourscripts{-Choice}{-Boxast}{-Boxbox}{-Boxcircle}{-Boxbslash}+

Output: $\fourscripts{\choice}{\boxast}{\boxbox}{\boxcircle}{\boxbslash}$
\item \Verb[commandchars=-\[\]]+\lrsubscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\lrsubscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\lrsuperscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\lrsuperscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\twolscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\twolscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\tworscripts{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\tworscripts{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\[\]]+\lsubscript{-Choice}{-Boxbox}+

Output: $\lsubscript{\choice}{\boxbox}$
\item \Verb[commandchars=-\[\]]+\lsuperscript{-Choice}{-Boxbox}+

Output: $\lsuperscript{\choice}{\boxbox}$
\item \Verb[commandchars=-\[\]]+\rsubscript{-Choice}{-Boxbox}+

Output: $\rsubscript{\choice}{\boxbox}$
\item \Verb[commandchars=-\[\]]+\rsuperscript{-Choice}{-Boxbox}+

Output: $\rsuperscript{\choice}{\boxbox}$
\end{itemize}}

\artsubsection{Changing the default lengths}
The following commands can be used to change the default skips between subscripts and/or superscripts and \Choice:
\begin{itemize}
\item\Verb[commandchars=-\[\]]+\setSingleLSkip{-Elll}+ changes the value of \Verb+\singleleftscriptskip+ to \Elll: this affects the skip in all the commands putting a subscript and/or a superscript on the left side of \Choice;
\item\Verb[commandchars=-\[\]]+\setSingleRSkip{-Ellr}+ changes the value of \Verb+\singlerightscriptskip+ to \Ellr: this affects the skip in all the commands putting a subscript and/or a superscript on the right side of \Choice;
\item\Verb[commandchars=-\[\]]+\setDblLSkip{-Elll}+ changes the value of \Verb+\dblleftscriptskip+ to \Elll: this affects the left skip in all the commands putting a subscript and/or a superscript on both sides of \Choice;
\item\Verb[commandchars=-\[\]]+\setDblRSkip{-Ellr}+ changes the value of \Verb+\dblrightscriptskip+ to \Ellr: this affects the right skip in all the commands putting a subscript and/or a superscript on both sides of \Choice.
\end{itemize}

\artsubsection{Custom lengths}
If you want to define the left and right skip on the sides of \Choice\ each time you write a command, you have the following options ($\ell_I$ is 2ex in these examples):

\begin{itemize}
\item \Verb[commandchars=-\[\]]+\fourscriptsC{-Choice}{-Boxast}{-Boxbox}{-Boxcircle}{-Boxbslash}{-Elll}{-Ellr}+

Output: $\fourscriptsC{\choice}{\boxast}{\boxbox}{\boxcircle}{\boxbslash}{2ex}{2ex}$
\item \Verb[commandchars=-\[\]]+\lrsubscriptsC{-Choice}{-Boxbox}{-Boxcircle}{-Elll}{-Ellr}+

Output: $\lrsubscriptsC{\choice}{\boxbox}{\boxcircle}{2ex}{2ex}$
\item \Verb[commandchars=-\[\]]+\lrsuperscriptsC{-Choice}{-Boxbox}{-Boxcircle}{-Elll}{-Ellr}+

Output: $\lrsuperscriptsC{\choice}{\boxbox}{\boxcircle}{2ex}{2ex}$
\item \Verb[commandchars=-\(\)]+\twolscripts[-Elll]{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\twolscripts[2ex]{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\(\)]+\tworscripts[-Ellr]{-Choice}{-Boxbox}{-Boxcircle}+

Output: $\tworscripts[2ex]{\choice}{\boxbox}{\boxcircle}$
\item \Verb[commandchars=-\(\)]+\lsubscript[-Elll]{-Choice}{-Boxbox}+

Output: $\lsubscript[2ex]{\choice}{\boxbox}$
\item \Verb[commandchars=-\(\)]+\lsuperscript[-Elll]{-Choice}{-Boxbox}+

Output: $\lsuperscript[2ex]{\choice}{\boxbox}$
\item \Verb[commandchars=-\(\)]+\rsubscript[-Ellr]{-Choice}{-Boxbox}+

Output: $\rsubscript[2ex]{\choice}{\boxbox}$
\item \Verb[commandchars=-\(\)]+\rsuperscript[-Ellr]{-Choice}{-Boxbox}+

Output: $\rsuperscript[2ex]{\choice}{\boxbox}$
\end{itemize}


\artsection{What does the package actually contains?}
You don't really need to read the following stuff to use the package, but have a look at it if you want to have an idea of how the package works without looking at the code.

\artsubsection{Lengths definitions}\label{lengths}
This lenghts are used to define the default skips on the left and on the right side of $\choice$.
\begin{itemize}
\item\Verb+\singleleftscriptskip+: default -0.27ex, larger\footnote{This is obtained after invoking the \verb+\largerSkips+ command.} -0.16ex;
\item\Verb+\singlerightscriptskip+: default -0.18ex, larger -0.07ex;
\item\Verb+\dblleftscriptskip+: default -0.75ex, larger 0ex;
\item\Verb+\dblrightscriptskip+: default -0.645ex, larger 0ex.
\end{itemize}

\artsubsection{Base commands}
The base commands are only three, all the rest is built on top of them:

\begin{itemize}
\item\Verb+\newcommand{\fourscriptsC}[7]+

\hspace{4ex}\Verb+{{\null}^{#2}_{#3}\hspace{#6}#1\hspace{#7}{\null}^{#4}_{#5}}+

\item\Verb+\newcommand{\twolscripts}[4]+

\hspace{4ex}\Verb+[\singleleftscriptskip]{{\null}^{#3}_{#4}\hspace{#1}#2}+

\item\Verb+\newcommand{\tworscripts}[4]+

\hspace{4ex}\Verb+[\singlerightscriptskip]{#2\hspace{#1}{\null}^{#3}_{#4}}+
\end{itemize}

\artsection{Contacts}
As you can see this package boils down to just a few new command definitions, but it can help save some time --- I wrote it because I was not really satisfied of what I had found searching the web.
