-
-  Tracker comes with a number of utilities that you can use:
-
-  * "tracker-applet" - notification applet which has various
-  utilities like displaying Tracker status, indexing progress,
-  and live statistics, pausing indexing, and launching both
-  tracker-search-tool and tracker-preferences
-
-  * "tracker-extract FILE" - this extracts embedded metadata from
-  FILE and prints to stdout
-
-  * "tracker-files" - returns files filtered by the mime type or
-  their category (see the manpage)
-
-  * "tracker-meta-folder" - return list of files indexed by Tracker
-  for a folder
-
-  * "tracker-preferences" - GUI tool to set Tracker preferences
-
-  * "tracker-query" - this reads an RDF Query that specifies the
-  search criteria for various fields. It prints to STDOUT all
-  matching files. You can see some example queries in the
-  RDF-Query-examples folder. You can run the examples as
-  "tracker-query < RDFFILE"
-
-  * "tracker-search SEARCHTERM" - this perfoms a google like search
-  using SEARCHTERM to retrieve all matching files where
-  SEARCHTERM appears in any searchable metadata
-
-  * "tracker-search-tool SEARCHTERM" - GUI search utility
-
-  * "tracker-stats" - this displays the current number of indexed
-  items by category
-
-  * "tracker-status" - queries status of trackerd
-
-  * "tracker-tag" - used for setting and searching tags/keywords
+  Tracker comes with a number of utilities that you can use. These are
+  hosted in src/utils/. To find out how to use them, provide the
+  --help command line switch to know how to they are used.
