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

whether already versioned or not, are searched for files or

with bzr send. If neither is specified, the default is the upstream branch
2775
or the branch most recently merged using --remember.

When merging a branch, by default the tip will be merged. To pick a different

revision, pass --revision. If you specify two values, the first will be used as
2779
BASE and the second one as OTHER. Merging individual revisions, or a subset of

available revisions, like this is commonly referred to as "cherrypicking".
2782
Revision numbers are always relative to the branch being merged.
2784
By default, bzr will try to merge in all new work from the other
2785
branch, automatically determining an appropriate base. If this
2786
fails, you may need to give an explicit base.
2788
Merge will do its best to combine the changes in two branches, but there
2789
are some kinds of problems only a human can fix. When it encounters those,
2790
it will mark a conflict. A conflict means that you need to fix something,
2791
before you should commit.
2793
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2795
If there is no default branch set, the first merge will set it. After
2796
that, you can omit the branch to use the default. To change the
2797
default, use --remember. The value will only be saved if the remote
2798
location can be accessed.

To remove only some changes, without reverting to a prior version, use

4052
* An optional bundle of revision data, so that the changes can be applied

4061
The submit branch defaults to the parent, but can be overridden. Both
4062
submit branch and public branch will be remembered if supplied.
4064
If a public_branch is known for the submit_branch, that public submit

Two formats are currently supported: "4" uses revision bundle format 4 and
4084
merge directive format 2. It is significantly faster and smaller than
4085
older formats. It is compatible with Bazaar 0.19 and later. It is the
4086
default. "0.9" uses revision bundle format 0.9 and merge directive
4087
format 1. It is compatible with Bazaar 0.12 - 0.18.
4089
Merge directives are applied using the merge command or the pull command.

A merge directive provides many things needed for requesting merges:
4241
* A machine-readable description of the merge to perform

* An optional patch that is a preview of the changes requested

* An optional bundle of revision data, so that the changes can be applied

If --no-bundle is specified, then public_branch is needed (and must be

4251

people can check it later.
4254
The submit branch defaults to the parent, but can be overridden. Both
4255
submit branch and public branch will be remembered if supplied.
4257
If a public_branch is known for the submit_branch, that public submit
