   date:       2006-11-26
   purpose:    demonstrate how to use the xsl-BSF-engine from ooRexx, modelled after
               "TableFiller.java"

   needs:      Java 1.4.x *or*

               Note on using Java 5, Java 6 or higher:

               - if the sample does not work in these environments then, copy the Xalan-jars from
                 "http://xml.apache.org/xalan-j/downloads.html" distribution into the "endorsed"
                 directory of these Java versions (e.g. "JAVA_JRE_HOME /jre/lib/endorsed/"); make
                 sure that the archive "xalan.jar" (from the xalan-tool jar) is available as well;
                 tested with Xalan 2.7 and 2.8 on Java 5 and beta-version of Java 6

   usage:      rexxj TableFiller.rex style1.xsl table-data.xml
               rexxj TableFiller.rex style2.xsl table-data.xml

   exit -1
