+## VSERVERS RELATED FUNCTIONS FOR NINJAHELPER
+##
+## Depends on:
+## - easydialog library
+## - $conffile
+##
+## Global variables used and modified here:
+## - $vservers_are_available (yes/no)
+## - $found_vservers (list)
+## - $selected_vservers (list)
+## - $host_or_vservers (host/vservers/both)
+##
+
+##
+## Get vservers-related variables.
+## Then, if Vservers are enabled, check that:
+## - VROOTDIR is valid;
+## - at least one vserver can be found.
+## If, and only if, the above conditions are all true:
+## - set $vservers_are_available to 'yes';
+## - set $found_vservers to the list of all vservers found on the system.
+## This function has to be run once before a new helper is run.
