tomcat -security startup problem

[Ian Davies <Da...@netscapeonline.co.uk>]

Hi there,
I've been trying to use Tomcat 3.2.1 to create servlets and use RMI
I ran up against problems with security manager, so followed the
instructions
on uncommenting the interceptor line in server.xml, and adding
an extra grant{..} for my stuff,
however when I try to invoke the tomcat startup.sh script with
the -security option, as instructed, after saying that it _has_ invoked
tomcat using this mode, it comes back with some verbose 'usage' help
info.
Is the script broken?
thanks for any help
Ian Davies.
