296
297
In recursive mode (the default), files are treated the same way

299
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

This command only works on branches that have not diverged. Branches are
492
considered diverged if the destination branch's most recent commit is one
493
that has not been merged (directly or indirectly) into the parent.
494
495
If branches have diverged, you can use 'bzr merge' to integrate the changes
496
from one into the other. Once one branch has merged, the other should
497
be able to pull it again.
498
499
If you want to forget your local changes and just update your branch to
500
match the remote one, use pull --overwrite.
501
502
If there is no default location set, the first pull will set it. After
503
that, you can omit the location to use the default. To change the
504
default, use --remember. The value will only be saved if the remote
505
location can be accessed.

2162
2163
The branch is the branch you will merge from. By default, it will merge
2164
the latest revision. If you specify a revision, that revision will be
2165
merged. If you specify two revisions, the first will be used as a BASE,
2166
and the second one as OTHER. Revision numbers are always relative to the
2167
specified branch.
2168
2169
By default, bzr will try to merge in all new work from the other
2170
branch, automatically determining an appropriate base. If this
2171
fails, you may need to give an explicit base.
2172
2173
Merge will do its best to combine the changes in two branches, but there
2174
are some kinds of problems only a human can fix. When it encounters those,
2175
it will mark a conflict. A conflict means that you need to fix something,
2176
before you should commit.
2177
2178
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2179
2180
If there is no default branch set, the first merge will set it. After
2181
that, you can omit the branch to use the default. To change the
2182
default, use --remember. The value will only be saved if the remote
2183
location can be accessed.
2184
2185
Examples:
2186
2187
To merge the latest revision from bzr.dev
2188
bzr merge ../bzr.dev
2189
2190
To merge changes up to and including revision 82 from bzr.dev
2191
bzr merge -r 82 ../bzr.dev
2192
2193
To merge the changes introduced by 82, without previous changes:
2194
bzr merge -r 81..82 ../bzr.dev
2195
2196
