+
+Agent Spawner maintains sets resources (agents) of certain kind and in certain
+number, according to given configuration.  Typical Resalloc resource is
+completely dummy, fully controlled from the outside.  With agent-like resources
+this is different — such resources are self-standing, they take care of
+themselves, perhaps interacting/competing with each other.  The only thing that
+agent-spawner needs to do is to control the ideal number of them.
