Instead of writing cout to a file, you really could capture the Fox
traces. The quote below is from 'Re: En:Welcome to the "Foxgui-announce"
mailing list':

"FOX may have tracing enabled when you've compiled it in debug mode.
Passing -tracelevel XX on the command line of any FOX application will
cause lots of logging info to be written, the higher the level XX, the
more you will see [all FOX library trace info is at level 100 or higher
so as to allow this tracing mechanism to be used in your own programs as
well]."
