 page that was processed (e.g., 37), and use the maintenance script with the
 `--start` option (or short `-s`) to indicate the start index:
 
-    php linktitles-cli.php -s 37
+    php extensions/LinkTitles/linktitles-cli.php -s 37
 
 For more verbose output that also includes the page title, use the `--verbose`

-    php linktitles-cli.php -s 37 -v
+    php extensions/LinkTitles/linktitles-cli.php -s 37 -v
 
 In verbose mode, the script will output all page titles one by one.
 
 See all available options with:
 
-    php linktitles-cli.php -h
