Metrics tools for C++

[Krice]

Any good free tools to calculate slightly more complicated metrics data (like number of classes) in a project? I have tried to find without luck. In fact I think writing such a tool yourself would not be super difficult, but I wouldn't want to waste my time on this if there are existing tools.

SourceMonitor does this, it seems to be quite old(?) program (that sweet xp style), but quite nice. It has mostly text data and some graphical stuff which I think is not that useful, but it's a free program so can't really complain.
