What I mean - I wouldn't mind commiting gnulib stuff to VCS, but only if I can omit files generated by autoreconf.
FWIW, that is exactly what I do for Texinfo. It helps my contributors to not spend time dealing with gnulib, and it helps me because it avoids gnulib-skew differences between me and my contributors. Of course, you have to be careful not to commit (and to .vcignore) the files generated by make, such as lib/foo.h when lib/foo.in.h exists. Feel free to peruse the Texinfo source repo (https://savannah.gnu.org/cvs/?group=texinfo) if you're interested. >From reading the manual, I got the impression that it is strictly the either-or approach, I think the manual (node "VCS Issues") could mention this "middle road" as a possibility. As far as I can see, you are correct that it only describes the all-or-nothing approach now. If the idea acceptable to the other gnulib folks, I could try to write a patch for it. Best, Karl
