  Log:
  Jakarta Commons Chain of Responsiblity library.
  
  The Chain API models a computation as a series of "commands" that can be
  combined into a "chain". The API for a command consists of a single method
  (execute()), which is passed a "context" parameter containing the dynamic state
  of the computation, and whose return value is a boolean that determines whether
  or not processing for the current chain has been completed (true), or whether
  processing should be delegated to the next command in the chain (false).
  
  Given that command implementations are designed to conform with these
  recommendations, it should be feasible to utilize the Chain of Responsibility
  APIs in the "front controller" of a web application framework (such as Struts),
  but also be able to use it in the business logic and persistence tiers to model
  complex computational requirements via composition. In addition, separation of a
  computation into discrete commands that operate on a general purpose context
  allows easier creation of commands that are unit testable, because the impact of
  executing a command can be directly measured by observing the corresponding
  state changes in the context that is supplied.
