Best Automatic Code Documenting Package?

Another member from the large Clan of Anonymous Coward asks: "I'd like to know people's experience with automatic code documentation packages, such as DOC++ and Kdoc.It seems as if they all have their advantages and disadvantages, without any being particularly 'the best'. If there's another package out there that supports both C and C++ while creating TexInfo and HTML output, that would be great!" Why limit this to just C++, code needs to be documented regardless of the language it's in.
