tutorial catdebug command

The tutorial webpage "Running a Custom Jetspeed Portal" gives the following instruction:

cd tomcat-express
cd bin

1. Windows
   catdebug
2. Linux
   ./catdebug.sh

The command "catdebug" does not seem to be an available batch file command in version 5.5 of Tomcat. Perhaps this was present in previous versions of Tomcat?

Workaround: execute "startup" instead of "catdebug"
