The <info>%command.name%</info> command lints a YAML file and outputs to STDOUT
the first encountered syntax error.
You can 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>
Or all YAML files in a bundle:
<info>php %command.full_name% @AcmeDemoBundle</info>
You can also pass the YAML contents from STDIN:
<info>cat filename | php %command.full_name%</info>
