+"""pyang plugin to convert a yang schema to a protobuf schema
+
+   - basic support for leaf, leaf-list, containers, list
+
+   - this plugin requires pyang to be present and is run using pyang as
+   follows:
+
+   $ pyang --plugindir /voltha/experiments/netconf/yang2proto -f yang2proto  -o
+   <protofile> -p /voltha/experiments/netconf/tests/yang2proto
+   /voltha/experiments/netconf/tests/yang2proto/<yang file>
+
+   - pyang validates the yang definition first and then invoke this plugin
+   to convert the yang model into protobuf.
