$0 --locale={locale_tag} [--locale=… --locale=… …] [--quiet] [--export-{locale_tag}={path}]  [--dumper-format] [--exclude-bracketed-strings] [--no-fallback]

Export locales from the Locale database in XML format.

Options:
  --help                       Show this help screen.
  --quiet                      Show less status output than normal. This also suppresses warnings related to locale string syntax.
  --locale={locale_tag}        Specify a locale to export. You may pass the flag multiple times in order to export multiple locales.
      This creates files in a default location that `/usr/local/cpanel/scripts/locale_import --locale={locale_tag}` knows to use.
  --export-{locale_tag}={file} Save the export of the locale {locale_tag} to {file} instead of the standard place.
      This creates files that can be imported with `/usr/local/cpanel/scripts/locale_import --import={file}`
  --dumper-format              Export into the old format instead of XLIFF (will force an .xml extension on any --export-XX paths)
  --recover                    Try to recover on encountering an ill-formed phrase.
  --exclude-bracketed-strings  Exclude strings that contain bracket notation, which may cause problems on some translation platforms.
  --no-fallback                Do not use original strings as fallback. If no translation is available, leave target blank.

The XML files that this script creates can be imported via /usr/local/cpanel/scripts/locale_import

If there were problems exporting the script will exit with an error status. To examine the details of what happened do not use --quiet.
