+Usage: dot -T png -O onapapidependecies.dot   This cmd will generate a png graph dependency file.
+Graphiz is the open source tool used to generate the graph.
+Graphiz is available and documented at http://www.graphviz.org
+This text file represents the API dependencies between ONAP projects
+The relation between producer and consumer is formalized by the following convention:
