+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 they 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 $2}'`)
+
+NINJAHELPER
+===========
+
+Ninjahelper is an additional script which will walk you through the process of
+configuring backupninja. Ninjahelper has a menu driven curses based interface
+(using dialog).
+
+To add an additional 'wizard' to ninjahelper, follow these steps:
+
+(1) to add a helper for the handler "blue", create the file
+ blue.helper in the directory where the handlers live.
+ (ie /usr/share/backupninja).
+
+(2) next, you need to add your helper to the global HELPERS variable
+ and define the main function for your helper (the function name
+ is always <helper>_wizard). for example, blue.helper:
+ HELPERS="$HELPERS blue:description_of_this_helper"
+ blue_wizard() {
+ ... do work here ...
+ }
+
+(3) look at the existing helpers to see how they are written. Try to re-use
+ functions, such as the dialog functions that are defined in easydialog.sh,
+ or the vserver functions defined in lib/vserver.
+
+(4) test, re-test, and test again. Try to break the helper by going backwards,
+ try to think like someone who has no idea how to configure your handler
+ would think, try to make your helper as simple as possible. Walk like a cat,
+ become your shadow, don't let your senses betray you.
