+This is an example showing a Dependency Manager "Adapter" in action. Two kinds of services are
+registered in the registry: some Device, and some DeviceParameter services. For each Device (having
+a given id), there is also a corresponding "DeviceParameter" service, having the same id.
+
+Then a "DeviceAccessImpl" adapter service is defined: it is used to "adapt" the "Device" service to
+a "DeviceAccess" service, which provides the union of each pair of Device/DeviceParameter having the
+same device.id . The adapter also dynamically propagate the service properties of the adapted Device
+service.
+
+So see logs, just type this command under gogo shell:
+
+g! log info|grep device.api

+
+This sample shows a "SpellChecker" application (using DM API) which provides a
+"dictionary:spellcheck" GOGO shell command. The GOGO "dictionary:spellcheck" command accepts a
+string as parameter, which is checked for proper existence. The SpellChecker class has a
+required/multiple (1..N) dependency over every available "DictionaryService" services, which are
+internally used by the SpellChecker command, when checking word existence.
+
+A DictionaryService is defined using a FactoryConfigurationAdapterService , allowing to instantiate
+many "DictionaryService" instances for each configuration that are added to the
+factory pid "Spell Checker Configuration (api)" from web console.
+The factory pid configuration metatypes are defined using the bnd "metatype" annotations
+(see DictionaryConfiguration.java).
+
+The DictionaryService is decorated with a DictionaryAspect, which you can instantiate by adding a
+configuration to the "Spell Checker Aspect Dictionary (api)" pid from web console. The
+aspect configuration metatype is also declared using the bnd metatype annotations (see
+DictionaryAspectConfiguration.java). 
+
+Before running this sample, go to webconsole, and add some words in the Spell Checker Configuration (api) factory PID, and
+in the Spell Checker Aspect Dictionary (api) PID.
+
+Then go to gogo shell, and type dm help. You will normally see the dictionary:spellcheck command.
+Type dictionary:spellcheck <some words configured either in the spell checker configuration, or in the spell checker aspect configuration, 
+and the dictionary will check for proper word existance in the configuration.

+The purpose of this sample is to show an example usage of the new "CompletableFuture" dependency that has been
+added in the dm-lambda library. CompletableFuture java8 class provides functional operations and promotes an asynchronous event-driven model.
+
+In such model, you can use the new dm-lambda library to add dependencies on asynchronous events using the standard JDK CompletableFuture class.
+
+In this example, the Activator first defines a PageLink component that depends on a LogService.
+The PageLink is initialized with the Felix web site URL and from the PageLinkImpl.init() method, the Felix web page is asynchronously downloaded,
+using a CompletableFuture. The CF is then added as a "FutureDependency" in the PageLinkImpl.init() method.
+And when the CF completes, the PageLinkImpl.start() callback is invoked and the service is registered.
+The Activator is then getting injected with the PageLink service, and displays the links (hrefs) found from the Felix web site.
