The <info>%command.name%</info> command extracts translation strings from templates
of a given bundle or the app folder. It can display them or merge the new ones into the translation files.

When new translation strings are found it can automatically add a prefix to the translation
message.

Example running against a Bundle (AcmeBundle)
  <info>php %command.full_name% --dump-messages en AcmeBundle</info>
  <info>php %command.full_name% --force --prefix="new_" fr AcmeBundle</info>

Example running against app messages (app/Resources folder)
  <info>php %command.full_name% --dump-messages en</info>
  <info>php %command.full_name% --force --prefix="new_" fr</info>
