> Hi.

> I contacted the doxygen maintainer, Warren Young, privately because I 
> had encountered a bug [1] in doxygen 1.7.4. I knew that this bug was 
> fixed in later versions of doxygen, and I asked if he could upload a 
> more recent version. Warren replied and very kindly offered me the 
> maintenance of doxygen for Cygwin.

> So I would like to adopt doxygen.
