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

Giving a list of files will revert only those files. Otherwise, all files

last committed revision is used.
3110
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.

3119
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

A merge directive provides many things needed for requesting merges:
3969
* A machine-readable description of the merge to perform
3971
* An optional patch that is a preview of the changes requested
3973
* An optional bundle of revision data, so that the changes can be applied
3974
directly from the merge directive, without retrieving data from a
3977
If --no-bundle is specified, then public_branch is needed (and must be
3978
up-to-date), so that the receiver can perform the merge using the
3979
public_branch. The public_branch is always included if known, so that
3980
people can check it later.
3982
The submit branch defaults to the parent, but can be overridden. Both
3983
submit branch and public branch will be remembered if supplied.
3985
If a public_branch is known for the submit_branch, that public submit
3986
branch is used in the merge instructions. This means that a local mirror
3987
can be used as your actual submit branch, once you have set public_branch
3990
Mail is sent using your preferred mail program. This should be transparent
3991
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
3992
If the preferred client can't be found (or used), your editor will be used.
3994
To use a specific mail program, set the mail_client configuration option.
3995
(For Thunderbird 1.5, this works around some bugs.) Supported values for
3996
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
3997
generic options are "default", "editor", "mapi", and "xdg-email".
3999
If mail is being sent, a to address is required. This can be supplied
4000
either on the commandline, or by setting the submit_to configuration
4003
Two formats are currently supported: "4" uses revision bundle format 4 and
4004
merge directive format 2. It is significantly faster and smaller than
4005
older formats. It is compatible with Bazaar 0.19 and later. It is the
4006
default. "0.9" uses revision bundle format 0.9 and merge directive

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

A merge directive provides many things needed for requesting merges:
4154
* A machine-readable description of the merge to perform
4156
* An optional patch that is a preview of the changes requested
4158
* An optional bundle of revision data, so that the changes can be applied

directly from the merge directive, without retrieving data from a

If --no-bundle is specified, then public_branch is needed (and must be
4163
up-to-date), so that the receiver can perform the merge using the
4164
public_branch. The public_branch is always included if known, so that
4165
people can check it later.
4167
The submit branch defaults to the parent, but can be overridden. Both
4168
submit branch and public branch will be remembered if supplied.
4170
If a public_branch is known for the submit_branch, that public submit
4171
branch is used in the merge instructions. This means that a local mirror
4172
can be used as your actual submit branch, once you have set public_branch

4176
merge directive format 2. It is significantly faster and smaller than

older formats. It is compatible with Bazaar 0.19 and later. It is the
4178
default. "0.9" uses revision bundle format 0.9 and merge directive
