\section*{Typographic conventions}
\index{typographic conventions}

\begin{itemize}
\item
  Code is written in monospace (typewriter) \texttt{like this}.
\item
  Commands that should be entered in a Unix shell
  are displayed as follows:
  \begin{code}
# ./configure
# make
  \end{code}
  Commands are written in the dialect of the \texttt{bash} shell. For
  other shells, such as \texttt{tcsh}, appropriate translations may be
  needed.
\end{itemize}

\section*{Enumeration and list indices}
\index{enumeration}
\index{indices}

Throughout this manual, elements $x_i$ of sets $\{x_i\}$ of size $n$
are enumerated from $i = 0$ to $i = n-1$. Derivatives in $\R^n$ are
enumerated similarly:
$\frac{\partial}{\partial x_0}, \frac{\partial}{\partial x_1},
 \ldots, \frac{\partial}{\partial x_{n-1}}$.
