 /**
  * Update the permalink structure.
  *
  * ## DESCRIPTION
  *
  * Updates the post permalink structure.
  *
  * To regenerate a .htaccess file with WP-CLI, you'll need to add the mod_rewrite module
  * to your wp-cli.yml or config.yml. For example:
  *
  * apache_modules:
  *   - mod_rewrite
  *
  * ## OPTIONS
  *
  * <permastruct>
  * : The new permalink structure to apply.
  *
  * [--category-base=<base>]
  * : Set the base for category permalinks, i.e. '/category/'.
  *
  * [--tag-base=<base>]
  * : Set the base for tag permalinks, i.e. '/tag/'.
  *
  * [--hard]
  * : Perform a hard flush - update `.htaccess` rules as well as rewrite rules in database.
  *
  * ## EXAMPLES
  *
  *     wp rewrite structure '/%year%/%monthnum%/%postname%'
