+.BI \-R " rootdir"
+The current directory will be changed to \fIrootdir\fR before
+running the script. Defaults to '/'. No chroot is done
+before running the script, so scripts should be aware of this
+and generally use relative paths. If neccessary and possible
+the script itself can chroot. Calling chroot(2) requires superuser
+privileges, so it would be impossible to run the scripts as a non
+root user if chroot was attempted.
