Test the heat-translator translation from command line as:
#heat-translator
--template-file=<path to the YAML template>
--template-type=<type of template e.g. tosca>
--parameters="purpose=test"
Takes three user arguments,
1. Path to the file that needs to be translated (required)
2. type of translation (e.g. tosca) (optional)
3. Input parameters (optional)
In order to use heat-translator to only validate template,
without actual translation, pass --validate-only=true along with
other required arguments.
