310
In non-recursive mode, all the named items are added, regardless
311
of whether they were previously ignored. A warning is given if
312
any of the named files are already versioned.
313
314
In recursive mode (the default), files are treated the same way
315
but the behaviour for directories is different. Directories that
316
are already versioned do not give a warning. All directories,
317
whether already versioned or not, are searched for files or
318
subdirectories that are neither versioned or ignored, and these
319
are added. This search proceeds recursively into versioned
320
directories. If no names are given '.' is assumed.
321
322
Therefore simply saying 'bzr add' will version all files that
323
are currently unknown.
324
325
Adding a file whose parent directory is not versioned will
326
implicitly add the parent, and so on up to the root. This means
327
you should never need to explicitly add a directory, they'll just
328
get added when you add a file in the directory.

330
--dry-run will show which files would be added, but not actually
331
add them.
332
333
--file-ids-from will try to use the file ids from the supplied path.
334
It looks up ids trying to find a matching parent directory with the
335
same filename, and then by pure path. This option is rarely needed
336
but can be useful when adding the same logical file into two
337
branches that will be merged later (without showing the two different
338
adds as a conflict). It is also useful when merging another project
339
into a subdirectory of this one.

argument to this option if required. This enables reproduction of the
2513
actual ordering used if and when an order sensitive problem is encountered.
2514
2515
If --list-only is given, the tests that would be run are listed. This is
2516
useful when combined with --first, --exclude and/or --randomize to
2517
understand their impact. The test harness reports "Listed nn tests in ..."
2518
instead of "Ran nn tests in ..." when list mode is enabled.
2519
2520
If the global option '--no-plugins' is given, plugins are not loaded
2521
before running the selftests. This has two effects: features provided or
2522
modified by plugins will not be tested, and tests provided by plugins will
2523
not be run.
2524
2525
Tests that need working space on disk use a common temporary directory,
2526
typically inside $TMPDIR or /tmp.
2527
2528
:Examples:
2529
Run only tests relating to 'ignore'::
2530
2531
bzr selftest ignore
2532
2533
Disable plugins and list tests as they're run::

2694
2695
The branch is the branch you will merge from. By default, it will merge
2696
the latest revision. If you specify a revision, that revision will be
2697
merged. If you specify two revisions, the first will be used as a BASE,
2698
and the second one as OTHER. Revision numbers are always relative to the
2699
specified branch.
2700
2701
By default, bzr will try to merge in all new work from the other
2702
branch, automatically determining an appropriate base. If this
2703
fails, you may need to give an explicit base.
2704
2705
Merge will do its best to combine the changes in two branches, but there
2706
are some kinds of problems only a human can fix. When it encounters those,
2707
it will mark a conflict. A conflict means that you need to fix something,
2708
before you should commit.
2709
2710
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2711
2712
If there is no default branch set, the first merge will set it. After
2713
that, you can omit the branch to use the default. To change the
2714
default, use --remember. The value will only be saved if the remote
2715
location can be accessed.
2716
2717
The results of the merge are placed into the destination working
2718
directory, where they can be reviewed (with bzr diff), tested, and then
2719
committed to record the result of the merge.
2720
2721
merge refuses to run if there are any uncommitted changes, unless
2722
--force is given.

3063
Giving a list of files will revert only those files. Otherwise, all files
3064
will be reverted. If the revision is not specified with '--revision', the
3065
last committed revision is used.
3066
3067
To remove only some changes, without reverting to a prior version, use
3068
merge instead. For example, "merge . --r-2..-3" will remove the changes
3069
introduced by -2, without affecting the changes introduced by -1. Or
3070
to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
3071
3072
By default, any files that have been manually changed will be backed up
3073
first. (Files changed only by merge are not backed up.) Backup files have
3074
'.~#~' appended to their name, where # is a number.
3075
3076
When you provide files, you can use their current pathname or the pathname
3077
from the target revision. So you can use revert to "undelete" a file by
3078
name. If you name a directory, all the contents of that directory will be
3079
reverted.
3080
3081
Any files that have been newly added since that revision will be deleted,
3082
with a backup kept if appropriate. Directories containing unknown files
3083
will not be deleted.
3084
3085
The working tree contains a list of pending merged revisions, which will
3086
be included as parents in the next commit. Normally, revert clears that
3087
list as well as reverting the files. If any files, are specified, revert
3088
leaves the pending merge list alnone and reverts only the files. Use "bzr
3089
revert ." in the tree root to revert all files but keep the merge record,
3090
and "bzr revert --forget-merges" to clear the pending merge list without
3091
reverting any files.

3869
3870
A merge directive provides many things needed for requesting merges:
3871
3872
* A machine-readable description of the merge to perform
3873
3874
* An optional patch that is a preview of the changes requested
3875
3876
* An optional bundle of revision data, so that the changes can be applied
3877
directly from the merge directive, without retrieving data from a
3878
branch.
3879
3880
If --no-bundle is specified, then public_branch is needed (and must be
3881
up-to-date), so that the receiver can perform the merge using the
3882
public_branch. The public_branch is always included if known, so that
3883
people can check it later.
3884
3885
The submit branch defaults to the parent, but can be overridden. Both
3886
submit branch and public branch will be remembered if supplied.
3887
3888
If a public_branch is known for the submit_branch, that public submit
3889
branch is used in the merge instructions. This means that a local mirror
3890
can be used as your actual submit branch, once you have set public_branch
3891
for that mirror.
3892
3893
Mail is sent using your preferred mail program. This should be transparent
3894
on Windows (it uses MAPI). On *nix, it requires the xdg-email utility. If
3895
the preferred client can't be found (or used), your editor will be used.
3896
3897
To use a specific mail program, set the mail_client configuration option.
3898
(For Thunderbird 1.5, this works around some bugs.) Supported values for
3899
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
3900
generic options are "default", "editor", "mapi", and "xdg-email".
3901
3902
If mail is being sent, a to address is required. This can be supplied
3903
either on the commandline, or by setting the submit_to configuration
3904
option.
3905
3906
Two formats are currently supported: "4" uses revision bundle format 4 and
3907
merge directive format 2. It is significantly faster and smaller than
3908
older formats. It is compatible with Bazaar 0.19 and later. It is the
3909
default. "0.9" uses revision bundle format 0.9 and merge directive
3910
format 1. It is compatible with Bazaar 0.12 - 0.18.

"""Create a merge-directive for submiting changes.
4053
4054
A merge directive provides many things needed for requesting merges:
4055
4056
* A machine-readable description of the merge to perform
4057
4058
* An optional patch that is a preview of the changes requested
4059
4060
* An optional bundle of revision data, so that the changes can be applied
4061
directly from the merge directive, without retrieving data from a
4062
branch.
4063
4064
If --no-bundle is specified, then public_branch is needed (and must be
4065
up-to-date), so that the receiver can perform the merge using the
4066
public_branch. The public_branch is always included if known, so that
4067
people can check it later.
4068
4069
The submit branch defaults to the parent, but can be overridden. Both
4070
submit branch and public branch will be remembered if supplied.
4071
4072
If a public_branch is known for the submit_branch, that public submit
4073
branch is used in the merge instructions. This means that a local mirror
4074
can be used as your actual submit branch, once you have set public_branch
4075
for that mirror.
4076
4077
Two formats are currently supported: "4" uses revision bundle format 4 and
4078
merge directive format 2. It is significantly faster and smaller than
4079
older formats. It is compatible with Bazaar 0.19 and later. It is the
4080
default. "0.9" uses revision bundle format 0.9 and merge directive
4081
format 1. It is compatible with Bazaar 0.12 - 0.18.
