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.

revision will be merged. If you specify two revisions, the first
1557
will be used as a BASE, and the second one as OTHER. Revision
1558
numbers are always relative to the specified branch.
1559
1560
By default bzr will try to merge in all new work from the other
1561
branch, automatically determining an appropriate base. If this
1562
fails, you may need to give an explicit base.
1563
1564
Examples:
1565
1566
To merge the latest revision from bzr.dev
1567
bzr merge ../bzr.dev
1568
1569
To merge changes up to and including revision 82 from bzr.dev
1570
bzr merge -r 82 ../bzr.dev
1571
1572
To merge the changes introduced by 82, without previous changes:
1573
bzr merge -r 81..82 ../bzr.dev
1574
1575
merge refuses to run if there are any uncommitted changes, unless
1576
--force is given.
