Roy,

Thanks for this... I was running into _both_ of these problems when
working on my thesis.

I agree on the 0.6.0 release.  There is a lot of functionality (and
robustness) present in CVS that's not in the 0.5.0 tarball!

Using Tomcat but need to do more? Need to support web services,
security?
