Breezy keeps track of changes to software source code (or similar information);

bazaar-ng is at an early stage of development, and the design is still changing from week to week. This man page here may be inconsistent with itself, with other documentation or with the code, and sometimes refer to features that are planned but not yet written. Comments are still very welcome; please send them to bazaar-ng@lists.canonical.com.
