   The following example comes with the PDFlib distribution for PHP 5.
   It uses the new exception handling and object encapsulation features
   available in PHP 5. It creates the file <var class="filename">hello.pdf</var>
   with one page. It defines some document info field contents, loads the
   Helvetica-Bold font and outputs the text &quot;Hello world! (says PHP)&quot;.
