Yes, the geometry stack is now using hg.  The same will be true for Diamondback.

If Arch/Gentoo/Fedora/Suse users want to take note, the Diamondback
instructions will need the appropriate 'mercurial' package listed as a
pre-depend, e.g.:

http://www.ros.org/wiki/diamondback/Installation/Arch
http://www.ros.org/wiki/diamondback/Installation/Fedora
http://www.ros.org/wiki/diamondback/Installation/Slackware
http://www.ros.org/wiki/diamondback/Installation/OpenSUSE
http://www.ros.org/wiki/diamondback/Installation/Gentoo

NOTE: the rest of the Diamondback install instructions won't work
until we start spinning the new Diamondback builds.
