-    The line
-        super().__init__( name , "recon::BeamElectronLocator" , "Recon" )
-
-    Calls the constructor for ldmxcfg.Producer, which is how we have handles
-    on this processor. You need to give the actual C++ class name with 
-    namespace(s) as the second entry, and the name of the module the C++ class
-    is in as the third entry.
-
-    Any other lines define parameters that are accessible in the C++
-    configure method. For example, the line
-        self.my_parameter = 20
-
-    defines a integer parameter for this class which can be accessed
-    in the configure method with
-        int my_parameter = parameters.getParameter<int>("my_parameter");
-
     Examples
     --------
 
-    Creating the configuration object gives the parameters set
-    in __init__.
-        beamEleFinder = BeamElectronLocator( 'beamEleFinder')
+    from LDMX.Recon.beamElectronLocator import BeamElectronLocator
+    beamEleFinder= BeamELectronLocator('beamEleFinder')
 
-    You can also change the parameters after creating this object.
-        beamELeFinder.my_parameter = 50
+    You can change the parameters after creating this object.
+        beamEleFinder.my_parameter = 50
 
     Then you put your processor into the sequence of the process.
