\section{Usage}
\label{sec:usage}

\subsection{Loading the package}
\label{sec:loading-package}

To load the package type
\begin{lstlisting}
\usepackage{subtext}
\end{lstlisting}
into your preamble.

\subsection{Using the package}
\label{sec:using-package}

In math mode use the \lstinline|_| character as usual to get the usual
result.
\begin{lstlisting}
\begin{equation}
  \label{eq:1}
  a_{long text}
\end{equation}
\end{lstlisting}
yielding
\begin{equation}
  \label{eq:1}
  a_{long text}
\end{equation}
Replace curly braces with square brackets to get the subscript typeset
using \texttt{amstext}'s \verb|\text| command.
\begin{lstlisting}
\begin{equation}
  \label{eq:2}
  a_[long text]
\end{equation}
\end{lstlisting}
yielding
\begin{equation}
  \label{eq:2}
  a_[long text]
\end{equation}
That's all!

\subsection{Package options}
\label{sec:package-options}

Due to the behaviour of the \texttt{amstext} \verb|\text| command, the
typeface of the text within the brackets is the same as the
surrounding text. This may not always be desirable -- I myself often
find it somewhat annoying. Thus there are two package options
\begin{description}
\setkomafont{descriptionlabel}{\ttfamily}
\item[upright] Makes the text within the brackets be in upright shape.
  The font family (sans serif, serif or others) and the series (e.g.
  boldface) is the same as the surrounding text. This is the authors
  favourite.

\item[normal] Makes the text within the brackets be in the documents
  \verb|\normalfont| style.
\end{description}
