+The host address can be updated dynamically. Give extra parameter `resolve`
+with a resolvable name:

+### One of several hosts
+
+Sometimes it is sufficient if one of a number of hosts is available. You can
+make `netwatch-notify` check for that by adding several items with same
+`hostname`. Note that `count` has to be multiplied to keep the actual time.
