Setting symbology of a layer using arcpy.mapping?

In the help docs they mention the ability to update layer symbology. (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Geoprocessing_scripts_for_map_document_management_and_output/00sr00000009000000/)

I haven't been able to find the function, class or module that does this. Can anyone point me in the right direction? Or does anyone have any examples to share?
