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

with bzr send. If neither is specified, the default is the upstream branch
2766
or the branch most recently merged using --remember.
2768
When merging a branch, by default the tip will be merged. To pick a different

BASE and the second one as OTHER. Merging individual revisions, or a subset of

available revisions, like this is commonly referred to as "cherrypicking".
2773
Revision numbers are always relative to the branch being merged.
2775
By default, bzr will try to merge in all new work from the other
2776
branch, automatically determining an appropriate base. If this
2777
fails, you may need to give an explicit base.
2779
Merge will do its best to combine the changes in two branches, but there
2780
are some kinds of problems only a human can fix. When it encounters those,
2781
it will mark a conflict. A conflict means that you need to fix something,
2782
before you should commit.
2784
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2786
If there is no default branch set, the first merge will set it. After
2787
that, you can omit the branch to use the default. To change the
2788
default, use --remember. The value will only be saved if the remote
2789
location can be accessed.

The results of the merge are placed into the destination working

3158
To remove only some changes, without reverting to a prior version, use

merge instead. For example, "merge . --revision -2..-3" will remove the

changes introduced by -2, without affecting the changes introduced by -1.

leaves the pending merge list alone and reverts only the files. Use "bzr

4060
A merge directive provides many things needed for requesting merges:
4062
* A machine-readable description of the merge to perform
4064
* An optional patch that is a preview of the changes requested
4066
* An optional bundle of revision data, so that the changes can be applied
4067
directly from the merge directive, without retrieving data from a
4070
If --no-bundle is specified, then public_branch is needed (and must be
4071
up-to-date), so that the receiver can perform the merge using the
4072
public_branch. The public_branch is always included if known, so that
4073
people can check it later.
4075
The submit branch defaults to the parent, but can be overridden. Both
4076
submit branch and public branch will be remembered if supplied.
4078
If a public_branch is known for the submit_branch, that public submit
4079
branch is used in the merge instructions. This means that a local mirror
4080
can be used as your actual submit branch, once you have set public_branch
4083
Mail is sent using your preferred mail program. This should be transparent
4084
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4085
If the preferred client can't be found (or used), your editor will be used.
4087
To use a specific mail program, set the mail_client configuration option.
4088
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4089
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4090
generic options are "default", "editor", "mapi", and "xdg-email".
4092
If mail is being sent, a to address is required. This can be supplied
4093
either on the commandline, by setting the submit_to configuration
4094
option in the branch itself or the child_submit_to configuration option
4095
in the submit branch.
4097
Two formats are currently supported: "4" uses revision bundle format 4 and
4098
merge directive format 2. It is significantly faster and smaller than
4099
older formats. It is compatible with Bazaar 0.19 and later. It is the

A merge directive provides many things needed for requesting merges:
4257
* A machine-readable description of the merge to perform
4259
* An optional patch that is a preview of the changes requested
4261
* An optional bundle of revision data, so that the changes can be applied
4262
directly from the merge directive, without retrieving data from a

If --no-bundle is specified, then public_branch is needed (and must be
4266
up-to-date), so that the receiver can perform the merge using the
4267
public_branch. The public_branch is always included if known, so that
4268
people can check it later.
4270
The submit branch defaults to the parent, but can be overridden. Both
4271
submit branch and public branch will be remembered if supplied.
4273
If a public_branch is known for the submit_branch, that public submit
4274
branch is used in the merge instructions. This means that a local mirror
4275
can be used as your actual submit branch, once you have set public_branch
