    <description lang="en">This script will analyze the media in your Libraries, lookup their "file creation time" and re-sort the library based on these timestamps. This is a great way to make the "Sort by: Date Added" feature in Library Mode more accurate. For example, when you reset your XBMC library, all files will be added in alphabetical order rather than by the date you added them to your system.</description>
