For a given method (eg. Settings.cpp getSettingByName()), I would like to get a **text** representation of the call graph. I've heard doxygen can generate an image of the call graph, I'm more interested in a text output.

For example, if I gave it "Settings.cpp getMethodByName" it would return:

```
Settings.cpp getSettingByName();
    SettingsWrapper.cpp getMaximumSpeed();
        ECU.cpp monitorSpeed();
            Operate.cpp runECU();
                Main.cpp run();
        CruiseControl.cpp accelerate();
            Operate.cpp runCruiseControl();
                Main.cpp run();
        Radio.cpp playApplauseThroughSpeakers();
            Operate.cpp runStereo();
                Main.cpp run(); 

```

Is this possible?

Many thanks, Fidel

ps. don't freak about the code, it's just an example.
