201
In non-recursive mode, all the named items are added, regardless

of whether they were previously ignored. A warning is given if
203
any of the named files are already versioned.
204
205
In recursive mode (the default), files are treated the same way
206
but the behaviour for directories is different. Directories that
207
are already versioned do not give a warning. All directories,
208
whether already versioned or not, are searched for files or
209
subdirectories that are neither versioned or ignored, and these
210
are added. This search proceeds recursively into versioned
211
directories. If no names are given '.' is assumed.
212
213
Therefore simply saying 'bzr add' will version all files that
214
are currently unknown.
215
216
Adding a file whose parent directory is not versioned will
217
implicitly add the parent, and so on up to the root. This means

you should never need to explictly add a directory, they'll just
219
get added when you add a file in the directory.

1551
1552
The branch is the branch you will merge from. By default, it will
1553
merge the latest revision. If you specify a revision, that
1554
revision will be merged. If you specify two revisions, the first
1555
will be used as a BASE, and the second one as OTHER. Revision
1556
numbers are always relative to the specified branch.
1557
1558
By default bzr will try to merge in all new work from the other
1559
branch, automatically determining an appropriate base. If this
1560
fails, you may need to give an explicit base.
1561
1562
Examples:
1563
1564
To merge the latest revision from bzr.dev
1565
bzr merge ../bzr.dev
1566
1567
To merge changes up to and including revision 82 from bzr.dev
1568
bzr merge -r 82 ../bzr.dev
1569
1570
To merge the changes introduced by 82, without previous changes:
1571
bzr merge -r 81..82 ../bzr.dev
1572
1573
merge refuses to run if there are any uncommitted changes, unless
