the latest revision. If you specify a revision, that revision will be
2079
merged. If you specify two revisions, the first will be used as a BASE,
2080
and the second one as OTHER. Revision numbers are always relative to the
2083
By default, bzr will try to merge in all new work from the other
2084
branch, automatically determining an appropriate base. If this
2085
fails, you may need to give an explicit base.
2087
Merge will do its best to combine the changes in two branches, but there
2088
are some kinds of problems only a human can fix. When it encounters those,
2089
it will mark a conflict. A conflict means that you need to fix something,
2090
before you should commit.
2092
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2094
If there is no default branch set, the first merge will set it. After
2095
that, you can omit the branch to use the default. To change the
2096
default, use --remember. The value will only be saved if the remote
2097
location can be accessed.
