  EngineRuleSet | RuleSet for processing the contents of a Engine definition element.
  ExpandWar | Expand out a WAR in a Host's appBase.
  FailedContext | An implementation of `Context` that is used as a place-holder for deployed applications when their deployment fails and a Context instance (usually `StandardContext` but may be any Context implementation) cannot be created.
  HomesUserDatabase | Concrete implementation of the `UserDatabase` interface considers all directories in a directory whose pathname is specified to our constructor to be "home" directories for those users.
  HostConfig | Startup event listener for a Host that configures the properties of that Host, and the associated defined contexts.
  HostConfig.DeployedApplication | This class represents the state of a deployed application, as well as the monitored resources.
