The <info>%command.name%</info> command extracts translation strings from your layouts.
It can display them or merge the new ones into the translation file.
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, and merge, translations from a given theme with <comment>--theme</> option:

  <info>php %command.full_name% --show --theme=hyde</info>
