Log message:
Apache Tomcat 6.x is the current focus of development. It builds upon the
improvements made in Tomcat 5.5.x and implements the Servlet 2.5 and JSP 2.1
specifications. In addition to that, it includes the following improvements:

* Memory usage optimizations
* Advanced IO capabilities
* Refactored clustering

- Use a more standard rc.d script
- Cleaner pkg_delete operation based on standard files/dirs that change
