+      processor (XSLTC) and the runtime support packages in xsltc.jar.
+      The reason to using this distribution is that you want more control.
+      If you are using just XSLTC you can put xsltc.jar on the classpath
+      and not xalan.jar. If you are using just the interpretive processor
+      you can put xalan.jar on the classpath and not xsltc.jar. Of course
+      you can put both xalan.jar and xsltc.jar from this distribution
+      on your classpath if you want to use both.
