+
+    This section is enabled when compilation symbol #NEED_DJVU_PROGRESS# is

+    routines do not need such a facility because it is sufficient to monitor
+    the calls to function \Ref{ByteStream::read} in class \Ref{ByteStream}.
+    
+    {\bf Code tracing macros} ---
+    Monitoring the progress of such complex algorithms requires significant
+    code support.  This is achieved by inserting {\em code tracing macros}
+    in strategic regions of the code.  
+    \begin{description}
+    \item[DJVU_PROGRESS_TASK(name,task,nsteps)]  indicates that the current
+         scope performs a task roughly divided in #nsteps# equal steps, with
+	       the specified #task# string used in the callback.
+    \item[DJVU_PROGRESS_RUN(name,tostep)] indicates that we are starting
+         an operation which will take us to step #tostep#.  The operation
+         will be considered finished when #DJVU_PROGRESS_RUN# will be called
+         again with an argument greater than #tostep#.  The execution of
+         this operation of course can be described by one subtask and so on.
+    \end{description}
+ 
+    {\bf Progress callback} --- Before defining the outermost task, you can
+    store a callback function pointer into the static member variable
+    #DjVuProgressTask::callback#.  This callback function is called
+    periodically with two unsigned long arguments.  The first argument is the
+    elapsed time. The second argument is the estimated total execution time.
+    Both times are given in milliseconds.
+
+    {\bf Important Note} --- This monitoring mechanism should not be used by
+    multithreaded programs.  */
