+**********************************************************
+Note: to get the greatest speedup from make -j you should also enable
+connection reuse in your ssh setup, e.g., by having the following lines
+in your .ssh/config:
+host *
+       ControlMaster auto
+       ControlPath ~/.ssh/ssh_mux_%h_%p_%r
+       ControlPersist 4h
+
+Please note, however, that maximum concurrent per-node reuse is usually
+set to something low (typically 10), and this is a problem if some node
+in your topology has many links. In this case you should raise that limit
+on the slivers, or limit makefile concurrency (e.g., by using make -j10).

        Uses GMAP_SERVER and GMAP_PROBES to run probes in selected slivers

        This of course is mostly a demo thing, based on a one-host ndnmap deployment for now
