Log Message:
-----------
Adding the original modjy demo application to the Demo subdirectory.
This application gives the users a complete running application that they can use as a template for aplication development.
In the future, we might develop a more sophisticated application.

+The WEB-INF/lib-python directory, if it exists, is automatically added 
+to sys.path. Adding jython modules into this directory will make them 
+available for import into your application.
+
+If you add your modules in a subdirectory, then be sure that that 
+subdirectory contains an __init__.py file, so that the subdirectory 
+is considered to be a package.
+
+See here for more details.

+To deploy this application
+
+1. Copy the jython.jar file into the WEB-INF/lib subdirectory 
+2. Set the value of python.home property in WEB-INF/web.xml so 
+   that it points to your jython installation.
+3. Copy this directory to the applications directory of your servlet
+   container. On Apache Tomcat, this is the "webapps" subdirectory
+   of the tomcat install directory.
+4. Enter the URL http://localhost:8080/modjy_webapp into your
+   browser.
+5. You should see a table containing the WSGI environment.
+
+Please see the installation documentation for more details.
