The <info>%command.name%</info> command lints a YAML file and outputs to STDOUT
the first encountered syntax error.

You can validates YAML contents passed from STDIN:

  <info>cat filename | php %command.full_name% -</info>

You can also validate the syntax of a file:

  <info>php %command.full_name% filename</info>

Or of a whole directory:

  <info>php %command.full_name% dirname</info>
  <info>php %command.full_name% dirname --format=json</info>

You can also exclude one or more specific files:

  <info>php %command.full_name% dirname --exclude="dirname/foo.yaml" --exclude="dirname/bar.yaml"</info>
