Emacs uses Git as its version control system since 2014-11-12. This page is therefore out of date and of mainly historical interest.

Refer instead to:

A Mercurial mirror of the Emacs Bazaar repository is available.

 hg clone http://hg.intevation.org/mirrors/gnu.org/emacs-trunk

I built another one on bitbucket:

 hg clone https://nic@bitbucket.org/nic/emacs 

which seems to be no longer maintained.
