+
+    In this version of wxLogTrace(), trace messages can be separated into

+    @ref overview_envvars "@c WXTRACE environment variable".
+

+    @beginDefList
+    @itemdef{ wxTRACE_MemAlloc, Trace memory allocation (new/delete) }
+    @itemdef{ wxTRACE_Messages, Trace window messages/X callbacks }

+          lead to function signature confusion in some cases: if you intend to
+          call the format string only version of wxLogTrace(), add a "%s"
+          format string parameter and then supply a second string parameter for
+          that "%s", the string mask version of wxLogTrace() will erroneously
+          get called instead, since you are supplying two string parameters to
+          the function. In this case you'll unfortunately have to avoid having
+          two leading string parameters, e.g. by adding a bogus integer (with
