Note that the "alt-dd" feature provides much of this, although certainly it
could be improved. When you deploy an application you can provide an
alternative deployment descriptor to be used in place of the deployment
descriptor in the application. This gives you some ability to specify
environment-specific per-deployment configuration information.
