* copied from the zip file after the database is upgraded.
*
* The files in the `$_new_bundled_files` list will be added to the installation
* if the version is greater than or equal to the old version being upgraded.
*
* The steps for the upgrader for after the new release is downloaded and
* unzipped is:
* 1. Test unzipped location for select files to ensure that unzipped worked.
* 2. Create the .maintenance file in current WordPress base.
* 3. Copy new WordPress directory over old WordPress files.
* 4. Upgrade WordPress to new version.
* 4.1. Copy all files/folders other than wp-content
* 4.2. Copy any language files to WP_LANG_DIR (which may differ from WP_CONTENT_DIR
* 4.3. Copy any new bundled themes/plugins to their respective locations
* 5. Delete new WordPress directory path.
* 6. Delete .maintenance file.
* 7. Remove old files.
* 8. Delete 'update_core' option.
*
* There are several areas of failure. For instance if PHP times out before step
* 6, then you will not be able to access any portion of your site. Also, since
* the upgrade will not continue where it left off, you will not be able to
* automatically remove old files and remove the 'update_core' option. This
* isn't that bad.
*
* If the copy of the new WordPress over the old fails, then the worse is that
* the new WordPress directory will remain.
*
* If it is assumed that every file will be copied over, including plugins and
* themes, then if you edit the default theme, you should rename it, so that
* your changes remain.
