-@section d2CPL Controllable Process Layer (CPL)
-
-D2 is built upon an abstract set of classes referred to as the Controllable
-Process Layer or CPL.  This layer provides the essentials for a controllable,
-configurable, asynchronous process.  They are the result of an effort to
-distill the common facets of process control currently duplicated in Kea's
-DHCP servers into a reusable construct.  The classes which form this abstract
-base are shown in the following class diagram:
-
-@image html abstract_app_classes.svg  "Controllable Process Layer Classes"
-
-- isc::d2::DControllerBase - provides all of the services necessary to manage
-an application process class derived from isc::d2::DProcess. These services include:
-    - Command line argument handling
-    - Process instantiation and initialization
-    - Support for stand-alone execution
-    - Process event loop invocation and shutdown
-
-    It creates and manages an instance of isc::d2::DProcessBase.  The CPL is
-    designed for asynchronous event processing applications.  It is constructed
-    to use ASIO library for IO processing.  @c DControllerBase owns an
-    isc::asiolink::IOService instance and it passes this into the @c
-    DProcessBase constructor. It is this @c IOService that is used to drive the
-    process's event loop.  The controller is designed to provide any interfaces
-    between the process it controls and the outside world.
-
-    @c DControllerBase provides configuration for its process via a JSON file
-    specified as a mandatory command line argument. The file structure is
-    expected be as follows:
-
-    { "<module-name>": {<module-config>} }
-
-    where:
-        - module-name : is a label which uniquely identifies the
-        configuration data for the (i.e. the controlled process.)
-        It is the value returned by @ref
-        isc::d2::DControllerBase::getAppName()
-
-        - module-config: a set of zero or more JSON elements which comprise
-        application's configuration values.  Element syntax is governed
-        by those elements supported in isc::cc.
-
-    The file may contain an arbitrary number of other modules.
-
-    @todo Eventually, some sort of secure socket interface which supports remote
-    control operations such as configuration changes or status reporting will
-    likely be implemented.
-
-- isc::d2::DProcessBase - defines an asynchronous-event processor (i.e.
-application) which provides a uniform interface to:
-    - Instantiate and initialize a process instance
-    - "Run" the application by starting its event loop
-    - Inject events to control the process
-It owns an instance of @c DCfgMgrBase.
-
-- isc::d2::DCfgMgrBase - provides the mechanisms for managing an application's
-configuration.  This includes services for parsing sets of configuration
-values, storing the parsed information in its converted form, and retrieving
-the information on demand.  It owns an instance of @c DCfgContextBase, which
-provides a "global" context for information that is accessible before, during,
-and after parsing.
-
-- isc::d2::DCfgContextBase - implements a container for configuration
-information or "context".  It provides a single enclosure for the storage of
-configuration parameters or any other information that needs to accessible
-within a given context.
-
-The following sequence diagram shows how a configuration from file moves
-through the CPL layer:
-
-@image html config_from_file_sequence.svg "CPL Configuration From File Sequence"
-
-The CPL classes will likely move into a common library.
-
-@subsection cplSignals CPL Signal Handling
-
-CPL supports interaction with the outside world via OS signals. The default
-implementation supports the following signal driven behavior:
-- SIGHUP receipt of this signal will cause a reloading of the configuration
-file.
-- SIGINT/SIGTERM receipt of either of these signals will initiate an
-orderly shutdown.
-
-CPL applications wait for for process asynchronous IO events through
-isc::asiolink::IOService::run() or its variants.  These calls are not
-interrupted upon signal receipt as is the select() function and while
-boost::asio provides a signal mechanism it requires linking in additional
-libraries.  Therefore, CPL provides its own signal handling mechanism to
-propagate an OS signal such as SIGHUP to an IOSerivce as a ready event with a
-callback.
-
-isc::d2::DControllerBase uses two mechanisms to carry out signal handling.  It
-uses isc::util::SignalSet to catch OS signals, and isc::d2:IOSignalQueue to
-propagate them to its isc::asiolink::IOService as instances of
-isc::d2::IOSignal.
-
-This CPL signaling class hierarchy is illustrated in the following diagram:
-
-@image html cpl_signal_classes.svg "CPL Signal Classes"
-
-The mechanics of isc::d2::IOSignal are straight forward. Upon construction it
-is given the target isc::asiolink::IOService, the value of the OS signal to
-send (e.g. SIGINT, SIGHUP...), and an isc::d2::IOSignalHandler.  This handler
-should contain the logic the caller would normally execute in its OS signal
-handler. Each isc::d2::IOSignal instance has a unique identifier called its
-sequence_id.
-
-Internally, IOSignal creates a 1 ms, one-shot timer, on the given
-IOService.  When the timer expires its event handler invokes the caller's
-IOSignalHandler passing it the sequence_id of the IOSignal.
-
-Sending IOSignals is done through an isc::d2::IOSignalQueue.  This class is
-used to create the signals, house them until they are delivered, and dequeue
-them so they can be been handled.  To generate an IOSignal when an OS signal
-arrives, the process's OS signal handler need only call
-isc::d2::IOSignalQueue::pushSignal() with the appropriate values.
-
-To dequeue the IOSignal inside the caller's IOSignalHandler, one simply
-invokes isc::d2::IOSignalQueue::popSignal() passing it the sequence_id
-parameter passed to the handler.  This method returns a pointer to
-instigating IOSignal from which the value of OS signal (i.e. SIGINT,
-SIGUSR1...) can be obtained.  Note that calling popSignal() removes the
-IOSignalPtr from the queue, which should reduce its reference count to
-zero upon exiting the handler (unless a deliberate copy of it is made).
-
-A typical isc::d2::IOSignalHandler might be structured as follows:
-@code
-
-    void processSignal(IOSignalId sequence_id) {
-    // Pop the signal instance off the queue.
-    IOSignalPtr signal = io_signal_queue_->popSignal(sequence_id);
-
-    int os_signal_value = signal->getSignum();
-    :
-    // logic based on the signal value
-    :
-    }
-
-@endcode
-
-IOSignal's handler invocation code will catch, log ,and then swallow any
-exceptions thrown by an IOSignalHandler.  This is done to protect the integrity
-IOService context.
-
-CPL integrates the use of the two mechanisms by registering the method,
-isc::d2::DControllerBase::osSignalHandler(), as the
-isc::util::SignalSet::onreceipt_handler_.  This configures SignalSet's internal
-handler to invoke the method each time a signal arrives.  When invoked, this
-method will call isc::d2::IOSignalQueue::pushSignal() to create an
-isc::d2::IOSignal, passing in the OS signal received and
-isc::d2::DControllerBase::ioSignalHandler() to use as the IOSignal's
-ready event handler
-
-The following sequence diagram depicts the initialization of signal handling
-during startup and the subsequent receipt of a SIGHUP:
