588 * copied to their locations.
589 *
590 * The files in the {@link $_old_files} list will be removed and the new files

592 *
593 * The files in the {@link $_new_bundled_files} list will be added to the installation
594 * if the version is greater than or equal to the old version being upgraded.
595 *
596 * The steps for the upgrader for after the new release is downloaded and
597 * unzipped is:
598 *   1. Test unzipped location for select files to ensure that unzipped worked.
599 *   2. Create the .maintenance file in current WordPress base.
600 *   3. Copy new WordPress directory over old WordPress files.
601 *   4. Upgrade WordPress to new version.
602 *     4.1. Copy all files/folders other than wp-content
603 *     4.2. Copy any language files to WP_LANG_DIR (which may differ from WP_CONTENT_DIR
604 *     4.3. Copy any new bundled themes/plugins to their respective locations
605 *   5. Delete new WordPress directory path.
606 *   6. Delete .maintenance file.
607 *   7. Remove old files.
608 *   8. Delete 'update_core' option.
609 *
610 * There are several areas of failure. For instance if PHP times out before step
611 * 6, then you will not be able to access any portion of your site. Also, since
612 * the upgrade will not continue where it left off, you will not be able to
613 * automatically remove old files and remove the 'update_core' option. This
614 * isn't that bad.
615 *
616 * If the copy of the new WordPress over the old fails, then the worse is that
617 * the new WordPress directory will remain.
618 *
619 * If it is assumed that every file will be copied over, including plugins and
620 * themes, then if you edit the default theme, you should rename it, so that
621 * your changes remain.
