+VSERVERS
+========
+
+If you are using Linux-Vservers (http://linux-vserver.org/) there are some
+special capabilities that different handlers have to make vserver backups easier.
+Set the variable "vservers" to be "yes" in /etc/backupninja.conf and see the
+example configuration files for each handler to configure the vserver specific
+variables.
+
+Additional vserver variables that can be configured in /etc/backupninja.conf. but
+probably don't need to be changed:
+
+VSERVERINFO (default: /usr/sbin/vserver-info)
+VSERVER (default: /usr/sbin/vserver)
+VROOTDIR (default: `$VSERVERINFO info SYSINFO |grep vserver-Rootdir | awk '{print $2}'; fi`)
