A.15. Bazaar-NG

Bazaar-NG (or bzr) is currently under development by Canonical (http://canonical.com/). It offers a choice between centralized and decentralized work within a single project. For example, when in the office, you can work on a shared central branch; for experimental changes or offline work you can make a branch on your laptop and merge back in later.
