A frequent problem with ClearCase builds when using a dynamic view is ensuring all the desired VOBs are already mounted prior to the build starting (or you don't want them all, see JENKINS-5389)

If the plugin could additionally take the user supplied text in the "Load rules" section for the job and pass it on in an environment variable (e.g. CLEARCASE_LOADRULES) I could change my existing jobs to do a 'cleartool mount <vobtag>' for each one. As it is now, I have to use a hard coded list for each job.
