Feels like a nit, but since it may affect another project owner's decision about whether to use the rewrite or not: there is no m4sh in there, it is portable she'll all the way down, and the repo is designed to work as a git submodule that easily interoperates with gnulib: https://github.com/gnulib-modules/bootstrap Pavel Raiskup kindly took over maintenance, and has considerably speeded up the script since then. Other pros and cons are discussed briefly in the README. > But while projects like libtool and M4 have used his > rewrite, no one really ever took the time to review it for inclusion in > upstream gnulib. It's not too late! :-) Cheers, Gary
