The [i18n:extract|INFO] task extracts i18n strings from your project files
for the given application and target culture:

  [./symfony i18n:extract frontend fr|INFO]

By default, the task only displays the number of new and old strings
it found in the current project.

If you want to display the new strings, use the [--display-new|COMMENT] option:

  [./symfony i18n:extract --display-new frontend fr|INFO]

To save them in the i18n message catalogue, use the [--auto-save|COMMENT] option:

  [./symfony i18n:extract --auto-save frontend fr|INFO]

If you want to display strings that are present in the i18n messages
catalogue but are not found in the application, use the 
[--display-old|COMMENT] option:

  [./symfony i18n:extract --display-old frontend fr|INFO]

To automatically delete old strings, use the [--auto-delete|COMMENT] but
be careful, especially if you have translations for plugins as they will
appear as old strings but they are not:

  [./symfony i18n:extract --auto-delete frontend fr|INFO]
