+{\bf Caveats:} since both the mask and the format string are strings,
+this might lead to function signature confusion in some cases:
+if you intend to call the format string only version of wxLogTrace,
+then 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 its \%d format string).
