+/**
+ * Ceph Dashboard node script
+ * This file should be used to aggregate all external scripts we need.
+ * Multiple flags can be used in the same call.
+ *
+ * Available flags:
+ * --env: Generates angular environment files.
+ *
+ * --pre: Modifies 'angular.json' to enable the build of custom locales using
+ *        angular --localize.
+ *        Languages can be defined using the environment variable DASHBOARD_FRONTEND_LANGS,
+ *        if no value is provided all languages will be build.
+ *        Default language is always build, even if not provided.
+ *        p.e.: 'DASHBOARD_FRONTEND_LANGS="pt" node cd --pre', will build EN and PT.
+ *        For backward compatibility we accept both long and short version of
+ *        languages, p.e.: 'pt' and 'pt-BR'
+ *
+ * --res: Restores 'angular.json' to its original and removes the backup file.
