324
In recursive mode (the default), files are treated the same way

326
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

directories. If no names are given '.' is assumed.

Therefore simply saying 'bzr add' will version all files that

are currently unknown.

Adding a file whose parent directory is not versioned will
336
implicitly add the parent, and so on up to the root. This means

get added when you add a file in the directory.

--file-ids-from will try to use the file ids from the supplied path.

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