title: How to place Email-Ext groovy script on the jenkins file system
body: <p>I need to dynamically modify the notification e-mail recipients based on the build, so I'm using a groovy script. I want this script to be available to all jobs, so I want it to reside on the Jenkins file system and not within each project. It can be either in the recipients fields (using ${SCRIPT,...}) or in the pre-send script. A short (fixed) script that evaluates the master script is also good, as long it is the same for all projects.</p>
