Folks, Beware, the following is extremely ugly Groovy. I've changed the names to protect the guilty (I think).
Also, the *_SVR and *_URL values are environment values stored centrally in Jenkins. That way they can be changed easily. They also show up in the job logs, which means with a little scripting effort I can get a history of what versions were deployed to what server when. Please review and laugh . . . or better yet, proffer improvements :-).

That way, everyone knows who did bad things to a server when. Sorry for the line wrap. . . . just my (ugly scripting) two cents /mde/
