     The Qweak analyzer framework consists of several components:
     - \ref QwAnalysis includes general analysis classes used by all packages listed below.
     - QwParity includes all instrumentation classes for parity analysis.
-    - QwTracking includes all classes for tracking analysis.
     - QwGUIMain includes all classes for the analysis GUI front-end.
 
 
     \subsection software_structure Structure of the analysis software
 
     All subsystems in the Qweak analyzer inherit from a single virtual base
     class VQwSubsystem.  The next level of detail is implemented as the
-    base subsystems for parity and tracking: VQwSubsystemParity and
-    VQwSubsystemTracking.  Finally, these are the base subsystems that
+    base subsystems for parity: VQwSubsystemParity.  Finally, these are the base subsystems that
     the specific subsystems (such as QwBeamLine or QwDriftChamber)
     inherit from, depending on what functionality they need to have.  Some
     subsystems (such as QwScanner) inherit from both base subsystems.
