metadata-tool v3.1.0

This tool is used to add metadata to readme.terraform.md

How to use

npm install -g metadata-tool
metadata-tool /path/to/your/readme.md

A possible readme.terraform.md maybe like this:

## terraform

These settings apply only when `--terraform` is specified on the command line.

``` yaml $(terraform)
terraform:
    cli-name: azurestack
    package-name: azurestack
clear-output-folder: true
output-folder: $(terraform-output-folder)/azurestack
