237
In recursive mode (the default), files are treated the same way

subdirectories that are neither versioned or ignored, and these

1926
1927
The branch is the branch you will merge from. By default, it will
1928
merge the latest revision. If you specify a revision, that
1929
revision will be merged. If you specify two revisions, the first
1930
will be used as a BASE, and the second one as OTHER. Revision
1931
numbers are always relative to the specified branch.
1932
1933
By default, bzr will try to merge in all new work from the other
1934
branch, automatically determining an appropriate base. If this
1935
fails, you may need to give an explicit base.
1936
1937
Merge will do its best to combine the changes in two branches, but there
1938
are some kinds of problems only a human can fix. When it encounters those,
1939
it will mark a conflict. A conflict means that you need to fix something,
1940
before you should commit.
1941
1942
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
1943
1944
If there is no default branch set, the first merge will set it. After
1945
that, you can omit the branch to use the default. To change the
1946
default, use --remember.
1947

Examples:
1949
1950

1953
To merge changes up to and including revision 82 from bzr.dev
1954

To merge the changes introduced by 82, without previous changes:

Use this if you want to try a different merge technique while resolving

lets you try different ones on different files.
2044
2045
The options for remerge have the same meaning and defaults as the ones for
2046
merge. The difference is that remerge can (only) be run when there is a
2047
pending merge, and it lets you specify particular files.
2048
2049
Examples:
2050
$ bzr remerge --show-base
2051
Re-do the merge of all conflicted files, and show the base text in
2052
conflict regions, in addition to the usual THIS and OTHER texts.
2053
2054
$ bzr remerge --merge-type weave --reprocess foobar
2055
Re-do the merge of "foobar", using the weave merge algorithm, with
2056
additional processing to reduce the size of conflict regions.
