PST2pdf is a Perl script which isolates all PostScript or
PSTricks related parts of the TeX document into single
LaTeX files, for which an eps and pdf image is created. 
The pdf ones are then imported in a last pdflatex run
for the pdf output of the main document. The eps and
pdf files are saved in a subdirectory images.

Syntax: PST2pdf.pl <file>.tex 

alternative: perl PST2pdf.pl <file>.tex


Some restrictions:
\begin{postscript}
...
\begin{pspicture}
....
\end{pspicture}
...
\end{postscript}

The pspicture environment can be nested, the postscript one NOT! 
pspicture can be inside of a postscript environment, but 
not vice versa.

The postscript environment should be used for all other
PostScript related commands, which are not part of
a pspicture environment, e.g. nodes inside normal text.

PST2pdf creates a document <file>-pdf.tex for use with
pdflatex, which then creates <file>-pdf.pdf. The created
images are named <file>-tmp-<No>.pdf
