Hi Richard,

Thank you for considering GPL -> GFDL compatibility.

In the meantime you write:

It is an interesting question.  One could use gtk-doc itself to identify
the lines that contain docstrings, and then vc-annotate to identify the
revisions that introduced those lines.  However I do not know how to
reliably trace authors back in history.  One can use heuristics from
vc-annotate-revision-previous-to-line; but probably the most accurate
way would be to do a set union on the authors of all lines within
docstring extents of all revisions in the repository.

I do not know of any existing software to do this, but something could
be hacked together with either gtk-doc or the regexps that it uses, and
git.  I do not think I will have time to do this, however.

Regards,

Andy
