/**
 * Xoops\Core\Locale\LegacyCodes - locale code to/from XOOPS legacy language directory names
 *
 * XOOPS 2.5.x and earlier used language defines for translations. These defines were stored in
 * in a directory structure in this form, where modulename is the module's "dirname" and
 * languagename is a lowercase english name for the language, i.e. "spanish" or "french":
 *
 *   modules/modulename/language/languagename/
 *   modules/modulename/language/languagename/admin.php
 *   modules/modulename/language/languagename/blocks.php
 *   modules/modulename/language/languagename/main.php
 *   modules/modulename/language/languagename/modinfo.php
 *   modules/modulename/language/languagename/help/help.html
 *   modules/modulename/language/languagename/mail_template/*.tpl
 *
 * This class provides a translation from a local code, such as "fr_FR," to the legacy
 * language name, so that language files in legacy modules can be loaded, if needed.
