 The functions below allow some limited customization of wxLog behaviour
 without writing a new log target class (which, aside of being a matter of
 several minutes, allows you to do anything you want).
 
 The verbose messages are the trace messages which are not disabled in the

-release mode and are generated by {\it wxLogVerbose()}. They are not normally
-shown to the user because they present little interest, but may be activated,
-for example, in order to help the user find some program problem.
-
-As for the (real) trace messages, they come in different kinds:
-\begin{itemize}\itemsep=0pt
-\item{wxTraceMemAlloc} for the messages about creating and deleting objects
-\item{wxTraceMessages} for tracing the windowing system messages/events
-\item{wxTraceResAlloc} for allocating and releasing the system ressources
-\item{wxTraceRefCount} for reference counting related messages
-\item{wxTraceOleCalls} for the OLE (or COM) method invocations (wxMSW only)
-\item{other} the remaining bits are free for user-defined trace levels
-\end{itemize}
-
-The trace mask is a bit mask which tells which (if any) of these trace
-messages are going to be actually logged. For the trace message to appear
-somewhere, all the bits in the mask used in the call to {\it wxLogTrace()}
-function must be set in the current trace mask. For example,
+release mode and are generated by \helpref{wxLogVerbose}{wxlogverbose}. They
+are not normally shown to the user because they present little interest, but
+may be activated, for example, in order to help the user find some program
+problem.
+
+As for the (real) trace messages, their handling depends on the settings of
+the (application global) {\it trace mask}. There are two ways to specify it:
+either by using \helpref{SetTraceMask}{wxlogsettracemask} and 
+\helpref{GetTraceMask}{wxloggettracemask} and using 
+\helpref{wxLogTrace}{wxlogtrace} which takes an integer mask or by using 
+\helpref{AddTraceMask}{wxlogaddtracemask} for string trace masks.
+
+The difference between bit-wise and string trace masks is that a message using
+integer trace mask will only be logged if all bits of the mask are set in the
+current mask while a message using string mask will be logged simply if the
+mask had been added before to the list of allowed ones.
+
+For example,
+
+\begin{verbatim}
+// wxTraceOleCalls is one of standard bit masks
+wxLogTrace(wxTraceRefCount | wxTraceOleCalls, "Active object ref count: %d", nRef);
+\end{verbatim}
+will do something only if the current trace mask contains both 
+{\tt wxTraceRefCount} and {\tt wxTraceOle}, but
+
+\begin{verbatim}
+// wxTRACE_OleCalls is one of standard string masks
+wxLogTrace(wxTRACE_OleCalls, "IFoo::Bar() called");
+\end{verbatim}
+
+will log the message if it was preceded by
+

 \begin{verbatim}
 \begin{verbatim}

-wxLogTrace(wxTraceRefCount | wxTraceOle, "Active object ref count: %d", nRef);
+wxLog::AddTraceMask(wxTRACE_OleCalls);

 \end{verbatim}
 \end{verbatim}

-will do something only if the current trace mask contains both wxTraceRefCount
-and wxTraceOle.
+
+Using string masks is simpler and allows to easily add custom ones, so this is
+the preferred way of working with trace messages. The integer trace mask is
+kept for compatibility and for additional (but very rarely needed) flexibility
+only.
+
+The standard trace masks are given in \helpref{wxLogTrace}{wxlogtrace} 
+documentation.
