/**
- * \ingroup Debug
* \brief Debug is an object for debugging in program.
* It has 2 debugging modes :
* - error : for bad library use, seriously wrong DICOM
* - debug : for information/debug messages
* - warning : for warning about DICOM quality (kosher)
+ * - assert : design by contract implementation. A function should have
+ * proper input and proper output.
+ * (should not happen, not user controlled)
*
- * A debugging message is only show if the flag is on (DebugFlag)
- * This is static var and can be set at begining of code:
+ * A debugging message is only shown if the flag is on (DebugFlag)
+ * This is static var and can be set at beginning of code:
