Did you know that you can embed PDF documents directly inside your
Regina data files?
This means that you can annotate your data with diagrams:

\bigskip

\centerline{
    \includegraphics[scale=0.35]{fig1}\qquad\qquad
    \includegraphics[scale=0.7]{fig2}}

\medskip

\noindent
and also with equations:

\[ \ldots
    \longrightarrow H_n(A \cap B)
    \stackrel{\Phi}{\longrightarrow} H_n(A) \oplus H_n(B)
    \stackrel{\Psi}{\longrightarrow} H_n(X)
    \stackrel{\partial}{\longrightarrow} H_{n-1}(A \cap B)
    \longrightarrow \ldots
\]

Simply write a document using your favourite word processor or
typesetting system (such as \LaTeX), convert it to PDF format, and import
your PDF into Regina by selecting \emph{New PDF Document} from the
\emph{Packet Tree} menu.

Regina will display your document using an external viewer, such as
\emph{evince} or \emph{okular} under Linux, or \emph{Preview} under
MacOS~X.  You can choose a different viewer by editing the PDF settings
in Regina's preferences.
