  * \ingroup Debug
  * \brief Debug is an object for debugging in program.
  * It has 2 debugging modes :
- *  - error : for bad library use
- *  - debug : for debugging messages
+ *  - error : for bad library use, seriously wrong DICOM
+ *  - debug : for information/debug messages
+ *  - warning : for warning about DICOM quality (kosher)
  * 
- * A debugging message has a level of priority and is 
- * Shown only when the debug level is higher than the 
- * message level.
+ * A debugging message is only show if the flag is on (DebugFlag)
+ * This is static var and can be set at begining of code:
+ *         gdcm::Debug::SetDebugOn();
