Resets the 64 bit OutputDirectory settings in the .vcproj files for
OpenSceneGraph and OpenThreads to be the same as the Win32
settings.  This is a workaround for Visual Studio's annoying practice of
generating this setting itself when creating the 64 bit configuration,
rather than reusing the Win32 setting.

To run, open a shell and execute
        perl $file

options:
  -h, --help               print help information
";
}

my ($print_help);
my $opt_success = GetOptions('h|help'           => \$print_help);

if (!$opt_success || $print_help) { print usage; exit !$print_help; }

  my ($filename) = @_;

  open(VCPROJ, "$filename") || die "$!";
  local($/) = undef;
  local($_) = <VCPROJ>;
  close(VCPROJ);
