+/**
+ * Base class for Application Manager Runtime plug-ins.
+ * 
+ * CAppMngr2Runtime class represents one Runtime plug-in. As it is abstract
+ * class plug-in must provide the actual implementation using derived class.
+ * 
+ * Application Manager lists ECom plug-ins implementing KAppMngr2PluginInterface
+ * and creates new CAppMngr2Runtime objects. Creating new CAppMngr2Runtime object
+ * loads the Runtime plug-in's DLL and instantiates it.
+ * 
+ * After all Runtime plug-ins are loaded, Application Manager calls LoadIconsL()
+ * to load plug-in specific icons, GetSupportedDataTypesL() to identify installation
+ * files that this plug-in support, and GetAdditionalDirsToScanL() to get plug-in
+ * specific directories that may contain installation files. Then Application Manager
+ * scans directories and recognizes files in them, and proceeds to get installed
+ * applications and installation packages. Installed applications are prompted from
+ * each plug-in via GetInstalledAppsL() method. Each plug-in creates CAppMngr2AppInfo
+ * derived objects to represent currently installed applications. Installation packages
+ * are based on recognized files in scanned directories. Application Manager provides
+ * list of files that match the supported data types via GetInstallationFilesL()
+ * method, and the plug-in creates CAppMngr2PackageInfo objects representing
+ * installation packages.
+ * 
+ * Application Manager monitors changes in scanned directories and known application
+ * registeries. When a change is notified, Application Manager gets the latest data
+ * using GetInstalledAppsL() and GetInstallationFilesL() methods again. If Application
+ * Manager does not listen some specific registry, plug-in can notify change using
+ * MAppMngr2RuntimeObserver interface.
