  * @brief     Implements the Firm interface to debug information.
  * @author    Goetz Lindenmaier, Michael Beck
  * @date      2001
- * @version   $Id$
- * @brief
- *  Firm requires a debugging module fulfilling this interface, else no
- *  debugging information is passed to the backend.
- *  The interface requires a datatype representing the debugging
- *  information.  Firm supports administrating a reference to the debug
- *  information in every Firm node.  Further Firm optimizations call
- *  routines to propagate debug information from old nodes to new nodes
- *  if the optimization replaces the old ones by the new ones.
