The package \LPack{pst-exa} was created to realize examples with printed code and output
side by side or on top of each other. The package looks in the image directory for the source
code of the examples and inserts only the code between the document environment ,
which is the sequence \LBEG{document} \ldots\ \LEND{document}.

The package provides the environment \Lenv{PSTexample} with the optional
arguments. For more information read the documentation of pst2pdf.

Using pst-exa makes only sense together with the Perl script pst2pdf, which
allows the use of Postscript code and running the document in pdf mode.
