+in almost all cases below it is recommended to use the -j option to make
+which was the point with uing make in the first place
+so that maximum degree of parallelism can be reached
+
+**********************************************************
+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).

==================== usual target
make [init+all]
shortcut for 'make init all'
make init
create util subdirs needed by this tool
-make all
+make -j all
initialize the whole topology on all nodes
==================== inspect donfig
make showslice
make sshchecks
make ovsversions
try out ssh connectivity to slivers in the slice, or show installed ovs version
+make sshs SSH-COMMAND="bla bla bla"
+ run "bla bla bla" in all slivers (and under sudo)
==================== For changing the topology on the fly
make L/<id1>-<id2>
create a link between nodes with ids <id1> and <id2>
make U/<id1>-<id2>
delete link between nodes with ids <id1> and <id2>
==================== cleanup
+make shutdown
+ tear down everything on the slivers, stops daemons and all
make clean
- clean up whatever has been created on the slivers
+ clean up whatever has been created on the slivers, keeps daemons running
make distclean
clean up local cache, useful when restarting from a clean slice
==================== configure (direct switches towards) OF controllers
make showcontrollers
show how OF controllers are configured from conf.mk
use CONTROLLER_<nodeid> if set, or CONTROLLER as a default otherwise
+ e.g. CONTROLLER=tcp:112.34.23.56:6633
+
make controllers
configure the various switches so they use the configured controllers
+make del-controllers
+ reset the switches to run in standalone mode
==================== devel
make update
push a new version of sliver-ovs into the slivers
make status
list status of db and switch processes in all slivers
====================
+make gprobes
+ Uses GMAP_SERVER and GMAP_PROBES to run probes in selected slivers
+ that can update a googlemap server for animating link speeds
+ This of course is mostly a demo thing, based on a one-host ndnmap deployment for now
