    # Genshi does strange things to get stuff out of the template   #
    # variables.  This stops it from handling properties in the     #
    # correct way as it returns the property rather than the actual #
    # value of the property.                                        #

    # By overriding lookup_attr() in the LookupBase class we are    #
    # able to get the required behaviour.  Using @property allows   #
    # us to move functionality out of templates whilst maintaining  #
    # backwards compatability.                                      #

    # correct way as it returns the property rather than the actual #
    # value of the property.                                        #

    # By overriding lookup_attr() in the LookupBase class we are    #
    # able to get the required behaviour.  Using @property allows   #
    # us to move functionality out of templates whilst maintaining  #
    # backwards compatability.                                      #

    # correct way as it returns the property rather than the actual #
    # value of the property.                                        #

    # By overriding lookup_attr() in the LookupBase class we are    #
    # able to get the required behaviour.  Using @property allows   #
    # us to move functionality out of templates whilst maintaining  #
    # backwards compatability.                                      #
