+  The Java Deployment Toolkit is utility to deploy Java content in
+  the browser as applets or applications using right version of Java.
+  If needed it can initiate upgrade of user's system to install required
+  components of Java platform.
+  <p>
+  Note that some of Deployment Toolkit methods may not be fully operational if
+  used before web page body is loaded (because DT native plugins could not be instantiated).
+  If you intend to use it before web page DOM tree is ready then dtjava.js
+  need to be loaded inside the body element of the page and before use of other DT APIs.
