+*
+*> \par Purpose:
+*  =============
+*>
+*> \verbatim
+*>
+*> XERBLA  is an error handler for the LAPACK routines.
+*> It is called by an LAPACK routine if an input parameter has an
+*> invalid value.  A message is printed and execution stops.
+*>
+*> Installers may consider modifying the STOP statement in order to
+*> call system-specific exception-handling facilities.
+*> \endverbatim
+*
+*  Arguments:
+*  ==========
+*
+*> \param[in] SRNAME
+*> \verbatim
+*>          SRNAME is CHARACTER*(*)
+*>          The name of the routine which called XERBLA.
+*> \endverbatim
+*>
+*> \param[in] INFO
+*> \verbatim
+*>          INFO is INTEGER
+*>          The position of the invalid parameter in the parameter list
+*>          of the calling routine.
