$0 [--locale={locale_tag} [--locale=… --locale=… …]] [--import={path} [--import=… --import=… …]] [--quiet] [--no-rebuild]

Import locales in XML format into the Locale database.

Options:
  --help                Show this help screen
  --quiet               Show less output than normal.
  --locale={locale_tag} Specify a locale to import. You can pass the flag multiple times in order to import multiple locales.
      This works on files in paths that `/usr/local/cpanel/scripts/locale_export --locale={locale_tag}` created.
  --import={file}       Specify the path to an XML file that is importable. You can pass the flag multiple times in order to import multiple files.
      This uses files in any arbitrary location and name.
  --no-rebuild          Do not rebuild the locale database after importing the XML file(s).
  --type={import_type}  Specify the import type as "xml" or "xlf" rather than guessing based on the file extension.

You must specify at least one --locale or --import flag.

The XML files that this script works with are created via /usr/local/cpanel/scripts/locale_export.

If nothing was imported the script will exit with an error status. To examine the reasons nothing was imported do not use --quiet.
