freopen( "vlc-help.txt", "w", stdout ); would redirect all print statements 
of whether they're intended for the help or not.

Having a FILE* to a new stream ensures you know that only the help info will 
be printed,
and not random debug info that happens to be in some of the code.

(Flimsy reasoning maybe, but valid and it should make the code
more obvious that you're printing to a file at first glance...)
