The GNU C++ standard library, libstdc++, uses doxygen to generate our API docs:
http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/

In order to prevent clashes with user-defined macros, standard library code must be "uglified" to use names reserved for the implementation i.e. you must use '__var' not 'var'

That uglification is an implementation detail, not part of the API.  It would greatly improve our docs if there could be a doxygen option to "de-uglify" names in the output.

So given:

    /** @param  t  The object to frob.
     */
    template<typename _Tp>
      _Tp frobnicate(_Tp __t);

I'd like the doxygen output to show the function as:

    template<typename Tp>
      Tp func(Tp t);

And also to recognise that the @param t relates to the parameter __t (rather than warning about undocumented parameters).

The alteration should only be done for function parameters and template parameters.  Functions, types and namespaces should not be altered.

Would something like this be possible?  If it would be relatively easy for someone unfamiliar with the Doxygen code to implement I could try to do so myself.
