In Emacs 23 (CVS Emacs) the vc interface supports hg, git, bzr and
maybe others.  But that is rather new and has still some rough edges.
E.g. the vc-annotate for hg only shows the the revision number and the
date but not the author who wrote the line.  Another annoyance is that
they synchronously call subprocesses the find-file-hook, apparently to
display the version number in the mode-line.  This can be rather slow
(not so much for SLIME, but for big repos).

To create a changeset one must mark the relevant files in the vc-dired
buffer and the marked files will then be committed together (not
individually as in older versions).  The diff command seem to work but
it doesn't honor `diff-switches' properly.  I think the log command
works only on one file if called in the buffer or on multiple files if
called in the vc-dired buffer.  There are no Emacs equivalents for the
status, pull, and push commands.

For git there exist some other Emacs packages, one is pcl-cvs-a-like.
I wasn't impressed by those.  The bzr-mode.el shipped with Bazaar was
even written by the illustrious Luke Gorrie.  Like his darcs-mode.el
it's simple but easily hackable.

Currently, I use hg primarily from the command line.
