Because the official bazaar repository might be slow, we include an option for | |
pulling HEAD from an unofficial Git mirror: | |
brew install emacs --HEAD- -use-git-head | |
There is inevitably some lag between checkins made to the official Emacs bazaar | |
repository and their appearance on the repo.or.cz mirror. See | |
http://repo.or.cz/w/emacs.git for the mirror's status. The Emacs devs do not | |
provide support for the git mirror, and they might reject bug reports filed | |
with git version information. Use it at your own risk. | |
