-// The content-layer specific implementation of RulesetServiceDelegate.
-//
-// Its main responsibility is receiving new versions of subresource filtering
-// rules from the RulesetService, and distributing them to renderer processes,
-// where they will be memory-mapped as-needed by the UnverifiedRulesetDealer.
-//
-// The distribution pipeline looks like this:
-//
-//                      RulesetService
-//                           |

-//          *RulesetDealer     |  *RulesetDealer
-//                 |                |       |
-//                 |           |    |       v
-//                 v                |      SubresourceFilterAgent
-//    SubresourceFilterAgent   |    v
-//                                SubresourceFilterAgent
-//                             |

-//         Renderer #1         |          Renderer #n

-// also a VerifiedRulesetDealer which is used similarly on the browser side.
