312
In recursive mode (the default), files are treated the same way

are already versioned do not give a warning. All directories,

whether already versioned or not, are searched for files or

subdirectories that are neither versioned or ignored, and these

are added. This search proceeds recursively into versioned

Merge will do its best to combine the changes in two branches, but there

Use bzr resolve when you have fixed a problem. See also bzr conflicts.

If there is no default branch set, the first merge will set it. After

default, use --remember. The value will only be saved if the remote
