\maketitle
The {\tt nfpi} style option gives you access to `Pi' fonts like Zapf
Dingbats and the PostScript Symbol font.

\begin{Pilist}{pzd}{'246}
\item \verb|\Pisymbol| generates a Pi character; it has two
parameters: the font family, and the character number. Thus
\verb|\Pisymbol{pzd}{'166}| generates \Pisymbol{pzd}{'166}.
\item \verb|\Pifill| (with the same parameters)
 acts like other filling commands, but fills the
space with a chosen symbol \Pifill{pzd}{'340} like that.
\item \verb|\Piline| generates a freestanding line of the little chaps:
\Piline{pzd}{36}
\item Inevitably, the {\tt Pilist} environment sets up an itemized
  list, but has a Pi character instead of a bullet (you are reading a
  \verb|Pilist| at the moment).
\begin{Pilist}{psy}{'247}
\item Do not forget the Symbol font
\item which can have effects like \Piline{psy}{"AA}
\item and individual symbols like \Pisymbol{psy}{"C4}
\end{Pilist}
\end{Pilist}

Then there is automatic incrementing of lists with Pi characters,
where the cross-referencing and nesting continues to work:

\begin{Piautolist}{pzd}{'254}
\item  text inside list, \label{d1} (d1)
  \begin{Piautolist}{psy}{'141}
  \item  text inside list, \label{c1} (c1)
  \item  text inside list, \label{c2} (c2)
    \begin{enumerate}
    \item  text inside list, \label{b1} (b1)
      \begin{Piautolist}{pzd}{'56}
      \item  text inside list, \label{a1} (a1)
      \item  text inside list, \label{a2} (a2)
      \item  text inside list, \label{a3} (a3)
      \end{Piautolist}
    \item  text inside list, \label{b2} (b2)
    \item  text inside list, \label{b3} (b3)
    \end{enumerate}
  \item  text inside list, \label{c3} (c3)
  \end{Piautolist}
\item  text inside list, \label{d2} (d2)
\item  text inside list, \label{d3} (d3)
\end{Piautolist}

\parindent=0em
\parskip=6pt

\begin{enumerate}
\item Better just check,\label{z1} (z1)
\item that normal enumerated lists,\label{z2}  (z2)
\item still work\label{z3}  (z3)
\end{enumerate}
