I think they already know about those performance problems, but it's always good to remind them that they're still not solved (especially the bulk transfer over `bzr' SHOULD be at least as fast as over http). > $ wget http://bzr.savanna.gnu.org/.../emacs-shared-repos.gz > $ tar zxvf emacs-shared-repos.gz > $ cd emacs-shared-repos (or whatever it's called) > $ cd trunk > $ bzr pull (pull down new revs into trunk) > $ bzr branch trunk my-branch (start working by branching trunk) > Seem sane to you? Yes, of course. Not just to save download time, but also because it then automatically sets up a shared repository, which is the sanest way to work with Bzr, in my experience. Stefan PS: Seeing that there's virtually no size difference between emacs-testing.tar.gz and emacs-testing.tar.lzma, I don't se the need to keep them both. And I also wonder if emacs-testing.tar wouldn't work just as well.
