//
// Abstract:
//
//    Implementation of the CRTApp class.  The CRTApp class is the base class
//    from which you derive an application object. An application object provides
//	  member functions for initializing your application and for  running the
//	  tasks. Each application can only contain one object derived from CRTApp.
//
// History:
//
//    V1.0	2003-03-06	Alex Duan	Original version.
//    V1.1	2003-06-25	Alex Duan	Module of RTOS moved to CRTObject class.
//    V1.2	2003-11-16	Alex Duan	Add a group of functions for profile saving
//									and restoring.
//	  V1.3	2006-09-11	Bozhong Xu	Support distribute system and sub system. 
//									Move initialize task from InitTask to InitInstance function.

//
//; System.ini
//; ==========
//;
//; This INI file contains information that is necessary for
//; firmware to support a device. The firmware reads this file
//; on startup and when the device changes. The format of the
//; contents may change at any time when the EFC updates.
//;
//; The entries have the following format, spaces can be added
//; before or after the equal sign:
//;
//; <Entry> = <Value>
//;
//; The [Device] section contains parameters of the whole device.
//; The [Message] section contains parameters of the communication.
//; The [Users] section contains parameters of system users.
//; The [Boards(m)] section contains parameters of one board.
//;   m(=0,1,...) is the index of the board in the device.
//; The [Interfaces(m,n)] section contains parameters of one interface.
//;   m(=0,1,...) is the index of the board;
//;   n(=0,1,...) is the index of the interface in the board.
//; Other sections can be added to this file too.
