The <info>%command.name%</info> command extracts translation strings from your layouts. It can display them or merge
the new ones into the translation files.
When new translation strings are found it automatically add a <info>NEW_</info> prefix to the translation message.

Example running against working directory:

  <info>php %command.full_name% --show</info>
  <info>php %command.full_name% --save --locale=en</info>

You can extract translations from a given theme with <comment>--theme</> option:
