is there a "C++" variant of gtk-doc?

[Percy Zahl <pzahl Mines EDU>]

Hello, 

I'm new to gtk-doc. I like to use it for my open software
project (http://gxsm.sf.net). It already works, but because I'm using
a lot of C++ classes I ran in some difficulties...

(I know gtk is "plain C only" in a objectoriented way)

I already had a look at the gtk-doc perl script, looks like it would
be possible to add a section which can handle C++ class definitions,
just similar to structs.

If there is already a "gtk-doc++" version hack availbe I'm very
interested in!
