+CLI entry point to show how TOSCA Parser can be used programmatically
+
+This is a basic command line utility showing the entry point in the
+TOSCA Parser and how to iterate over parsed template. It can be extended
+or modified to fit an individual need.
+
+It can be used as,
+#tosca-parser --template-file=<path to the YAML template>
+#tosca-parser --template-file=<path to the CSAR zip file>
+#tosca-parser --template-file=<URL to the template or CSAR>
+
+e.g.
+#tosca-parser
+ --template-file=toscaparser/tests/data/tosca_helloworld.yaml
+#tosca-parser
+ --template-file=toscaparser/tests/data/CSAR/csar_hello_world.zip
