[rules-users] How do I totally clear out an installation of Guvnor (Tomcat 6.0)

Hi there, I'm migrating to Guvnor RC atm, and was wanting to completely clear out my Guvnor Packages files before I did so - I wanted everything gone. I thought that all information was stored in the Guvnor folder created in Tomcat/webapps, so I deleted that, restarted the server and dragged in the new Guvnor RC WAR file. This built itself fine and is up and running on the server - but my packages are still there! Where abouts are these kept in Apache Tomcat? I can't just delete them from within Guvnor because despite me being able to delete most of the files/packages/etc, there are three categories that claim to be 'still in use' and won't let me delete them... even though there are *no* other files left! Any help is much appreciated. Stephen -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
