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.
