custom email alert sample

Hi, I've been looking into customizing the email alerts that get sent from our xymon server.? I've played with the SMS option and like the minimal content of the body of the email, but I still want a customized Subject and I want the alert URL included in the email body.? I assume the SCRIPT option will accomplish this.? Does anyone have a simple script that they can share?
Thanks.
