# ActionFilter is a base class for actions that are triggered by
# specs that match the filter. The filter may be specified by
# strings that match spec descriptions or by tags for strings
# that match spec descriptions.
#
# Unlike TagFilter and RegexpFilter, ActionFilter instances do
# not affect the specs that are run. The filter is only used to
# trigger the action.
