258
259
In recursive mode (the default), files are treated the same way

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

2099
2100
The branch is the branch you will merge from. By default, it will merge
2101
the latest revision. If you specify a revision, that revision will be
2102
merged. If you specify two revisions, the first will be used as a BASE,
2103
and the second one as OTHER. Revision numbers are always relative to the
2104
specified branch.
2105
2106
By default, bzr will try to merge in all new work from the other
2107
branch, automatically determining an appropriate base. If this
2108
fails, you may need to give an explicit base.
2109
2110
Merge will do its best to combine the changes in two branches, but there
2111
are some kinds of problems only a human can fix. When it encounters those,
2112
it will mark a conflict. A conflict means that you need to fix something,
2113
before you should commit.
2114
2115
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2116
2117
If there is no default branch set, the first merge will set it. After
2118
that, you can omit the branch to use the default. To change the
2119
default, use --remember. The value will only be saved if the remote
2120
location can be accessed.
2121
2122
Examples:
2123
2124
To merge the latest revision from bzr.dev
2125
bzr merge ../bzr.dev
2126
2127
To merge changes up to and including revision 82 from bzr.dev
2128
bzr merge -r 82 ../bzr.dev
2129
2130
To merge the changes introduced by 82, without previous changes:
2131
bzr merge -r 81..82 ../bzr.dev
2132
2133
merge refuses to run if there are any uncommitted changes, unless
