Utility to verify Puppet metadata.json files

 This tool lets users verify that a file in Puppet modules, metadata.json,
 conforms to the format that it is expected to have.
 .
 The metadata.json file is used when publishing a module to the public module
 repository on forge.puppet.com, or to a private module forge. With this
 information, you can expose dependencies to other modules, set Puppet version
 requirements and expose the module's license, author and other such metadata.
 .
 metadata-json-lint can be used directly, or it can be used through
 puppet-development-kit.
