Parser YANG2TOSCA
========================
Overview
===========================
Parser is an open source project and licensed under Apache 2. Parser will help
to provide a tooling mechanism, by parsing Telecom operators’ VNF descriptors
(YANG templates) into TOSCA templates and then further translate TOSCA
templates into certain common templates, which could be used in IaaS orchestration
projects like OpenStack Heat.
Prerequisites

Parser requires the following to be installed.
1. PYANG

Please follow the below installation steps.
Step 1: Clone pyang tool or download the zip file from the following link.

or
wget https://github.com/mbj4668/pyang/archive/master.zip
Step 2: Change directory to the downloaded directory and run the setup file.

Execution
===========================
