300
301
In recursive mode (the default), files are treated the same way

but the behaviour for directories is different. Directories that
303
are already versioned do not give a warning. All directories,
304
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

2187
2188
The branch is the branch you will merge from. By default, it will merge
2189
the latest revision. If you specify a revision, that revision will be
2190
merged. If you specify two revisions, the first will be used as a BASE,
2191
and the second one as OTHER. Revision numbers are always relative to the
2192
specified branch.
2193
2194
By default, bzr will try to merge in all new work from the other
2195
branch, automatically determining an appropriate base. If this
2196
fails, you may need to give an explicit base.
2197
2198
Merge will do its best to combine the changes in two branches, but there
2199
are some kinds of problems only a human can fix. When it encounters those,
2200
it will mark a conflict. A conflict means that you need to fix something,
2201
before you should commit.
2202
2203
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2204
2205
If there is no default branch set, the first merge will set it. After
2206
that, you can omit the branch to use the default. To change the
2207
default, use --remember. The value will only be saved if the remote
2208
location can be accessed.
2209
2210
Examples:
2211
2212
To merge the latest revision from bzr.dev
2213
bzr merge ../bzr.dev
2214
2215
To merge changes up to and including revision 82 from bzr.dev
2216
bzr merge -r 82 ../bzr.dev
2217
2218
To merge the changes introduced by 82, without previous changes:
2219
bzr merge -r 81..82 ../bzr.dev
