Introduction

\begin_layout Standard
In order to properly typeset the document and have instant preview working,
 the following packages have to be installed:
\end_layout

\begin_layout LyX-Code
xy,
 qtree,
 tipa,
 pstricks,
 pst-plot,
 rotating,
 tikz,
 pgf,
 etex
\end_layout

\begin_layout Standard
Due to the use of postscript specials in Section 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:PSTricks"
nolink "false"

\end_inset

,
 only the Postscript or PDF (ps2pdf) output formats will correctly render the included images.
 Starting with TeX Live 2021,
 you may need to add the flag 
\family typewriter
-dALLOWPSTRANSPARENCY
\family default
 to the 
\family typewriter
ps2pdf
\family default
 converter.
 The PDF (Xe\SpecialChar TeX
) output seems to also work,
 while trying to typeset the document with 
\family typewriter
pdflatex
\family default
 or 
\family typewriter
pdflualatex
\family default
 will generate errors.
