/**
 * Exports a JasperReports document to RTF format. 
 * <p/>
 * The {@link net.sf.jasperreports.engine.export.JRRtfExporter} implementation helps
 * to export JasperPrint documents in RTF format using RTF Specification 1.6. This
 * means that the RTF files produced by this exporter are compatible with Microsoft Word
 * 6.0, 2003 and XP.
 * <p/>
 * However, users might experience some problems when opening those RTF files with
 * OpenOffice or StarOffice, as these products are not perfectly compatible with the RTF
 * specifications from Microsoft.
 * <p/>
 * RTF is a character-based file format that supports absolute positioning of elements,
 * which means that this exporter produces output very similar to that of the <code>Graphics2D</code>
 * and PDF exporters. The {@link net.sf.jasperreports.export.RtfReportConfiguration} provides special 
 * configuration settings for this exporter.
 * <p/>
 * Almost all the provided samples show how to export to RTF.
 * 
 * @see net.sf.jasperreports.export.RtfReportConfiguration
