+\item[Select directories to scan.]
+  The database normally scans all directories for audio files. This setting
+  allows you to limit the scan to a specified list of directories, so only
+  files contained in one of these directories will be added to the database.
+  Scanning is recursive -- all subdirectories of a selected directory will
+  be scanned as well.
