I'd really prefer we didn't do this, and preferably obsoleted/removed the existing environment variables. IMHO using environment variables is a really bad idea and should be avoided wherever possible. Environment variables are about the worst user interface I can think of. For a start they're a global resource, which is limited on some systems. It's also extremely hard to determine what environment a user is running. This makes reproducing user bugs somewhere between hard and impossible. Paul
