last committed revision is used.
3133
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.

When you provide files, you can use their current pathname or the pathname

list as well as reverting the files. If any files are specified, revert

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

4006
A merge directive provides many things needed for requesting merges:
4008
* A machine-readable description of the merge to perform
4010
* An optional patch that is a preview of the changes requested
4012
* An optional bundle of revision data, so that the changes can be applied
4013
directly from the merge directive, without retrieving data from a
4016
If --no-bundle is specified, then public_branch is needed (and must be
4017
up-to-date), so that the receiver can perform the merge using the
4018
public_branch. The public_branch is always included if known, so that
4019
people can check it later.
4021
The submit branch defaults to the parent, but can be overridden. Both
4022
submit branch and public branch will be remembered if supplied.
4024
If a public_branch is known for the submit_branch, that public submit
4025
branch is used in the merge instructions. This means that a local mirror
4026
can be used as your actual submit branch, once you have set public_branch
4029
Mail is sent using your preferred mail program. This should be transparent
4030
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4031
If the preferred client can't be found (or used), your editor will be used.
4033
To use a specific mail program, set the mail_client configuration option.
4034
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4035
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4036
generic options are "default", "editor", "mapi", and "xdg-email".
4038
If mail is being sent, a to address is required. This can be supplied
4039
either on the commandline, or by setting the submit_to configuration
4042
Two formats are currently supported: "4" uses revision bundle format 4 and
4043
merge directive format 2. It is significantly faster and smaller than
4044
older formats. It is compatible with Bazaar 0.19 and later. It is the
4045
default. "0.9" uses revision bundle format 0.9 and merge directive

format 1. It is compatible with Bazaar 0.12 - 0.18.

4192
A merge directive provides many things needed for requesting merges:
4194
* A machine-readable description of the merge to perform
4196
* An optional patch that is a preview of the changes requested
4198
* An optional bundle of revision data, so that the changes can be applied
4199
directly from the merge directive, without retrieving data from a

If --no-bundle is specified, then public_branch is needed (and must be
4203
up-to-date), so that the receiver can perform the merge using the
4204
public_branch. The public_branch is always included if known, so that
4205
people can check it later.
4207
The submit branch defaults to the parent, but can be overridden. Both
4208
submit branch and public branch will be remembered if supplied.
4210
If a public_branch is known for the submit_branch, that public submit
4211
branch is used in the merge instructions. This means that a local mirror
4212
can be used as your actual submit branch, once you have set public_branch

Two formats are currently supported: "4" uses revision bundle format 4 and
4216
merge directive format 2. It is significantly faster and smaller than
4217
older formats. It is compatible with Bazaar 0.19 and later. It is the
4218
default. "0.9" uses revision bundle format 0.9 and merge directive

format 1. It is compatible with Bazaar 0.12 - 0.18.
