\centerline{\large\bf Examples: Drawing arrows on \emph{qtree} trees}
\medskip
The arrow-drawing capabilities of the package \emph{tree-dvips} (written by
Emma Pease) can be used with trees drawn with \emph{qtree}.  The two packages
are fully compatible.  

Note, however, that tree-dvips relies on PostScript specials, and thus does not work with pdf\LaTeX. This file was generated as DVI and then converted to pdf. 

\emph{Tree-dvips} is not included in the distribution of \emph{qtree;} it is
available on CTAN.

Thanks to Seth Kulick for telling me about the combination, and to Amanda
Seidl for contributing the verb-movement example.

% A little bug: Because of how TeX assigns type categories to its input, the
% automatic math-mode switching of label subscripts does not work inside
% footnotes or boxes.  To work around this, invoke \verb|\automath|
% \emph{before} entering in the box or footnote.  (This will enable
% auto-switching to math mode anywhere in the text).
