--- Comment #1 from Tom Tromey <tromey at gcc dot gnu.org> --- This is pretty easy to fix in gcc/jit/docs/conf.py: diff --git a/gcc/jit/docs/conf.py b/gcc/jit/docs/conf.py index 3e630db47ef..1224bdcc07d 100644 --- a/gcc/jit/docs/conf.py +++ b/gcc/jit/docs/conf.py @@ -244,7 +244,7 @@ man_pages = [ # dir menu entry, description, category) texinfo_documents = [ ('index', 'libgccjit', u'libgccjit Documentation', - u'David Malcolm', 'libgccjit', 'One line description of project.', + u'David Malcolm', 'libgccjit', 'GCC-based Just In Time compiler library.', 'Miscellaneous'), ] However, I don't have the version of sphinx that was used to generate the docs, and when I run the version I do have, there are tons of changes. So, maybe someone else ought to do this part.
