In non-recursive mode, all the named items are added, regardless

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

you should never need to explicitly add a directory, they'll just
328
get added when you add a file in the directory.

--dry-run will show which files would be added, but not actually

add them.

--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

If arguments are given, they are regular expressions that say which tests
2561
should run. Tests matching any expression are run, and other tests are
2562
not run.
2563
2564
Alternatively if --first is given, matching tests are run first and then
2565
all other tests are run. This is useful if you have been working in a
2566
particular area, but want to make sure nothing else was broken.
2567
2568
If --exclude is given, tests that match that regular expression are
2569
excluded, regardless of whether they match --first or not.
2570
2571
To help catch accidential dependencies between tests, the --randomize
2572
option is useful. In most cases, the argument used is the word 'now'.
2573
Note that the seed used for the random number generator is displayed
2574
when this option is used. The seed can be explicitly passed as the
2575
argument to this option if required. This enables reproduction of the
2576
actual ordering used if and when an order sensitive problem is encountered.
2577
2578
If --list-only is given, the tests that would be run are listed. This is
2579
useful when combined with --first, --exclude and/or --randomize to
2580
understand their impact. The test harness reports "Listed nn tests in ..."
2581
instead of "Ran nn tests in ..." when list mode is enabled.
2582
2583
If the global option '--no-plugins' is given, plugins are not loaded
2584
before running the selftests. This has two effects: features provided or
2585
modified by plugins will not be tested, and tests provided by plugins will
2586
not be run.
2587
2588
Tests that need working space on disk use a common temporary directory,
2589
typically inside $TMPDIR or /tmp.
2590
2591
:Examples:
2592
Run only tests relating to 'ignore'::

The source of the merge can be specified either in the form of a branch,
2770
or in the form of a path to a file containing a merge directive generated
2771
with bzr send. If neither is specified, the default is the upstream branch
2772
or the branch most recently merged using --remember.
2773
2774
When merging a branch, by default the tip will be merged. To pick a different
2775
revision, pass --revision. If you specify two values, the first will be used as
2776
BASE and the second one as OTHER. Merging individual revisions, or a subset of
2777
available revisions, like this is commonly referred to as "cherrypicking".
2778
2779
Revision numbers are always relative to the branch being merged.
2780
2781
By default, bzr will try to merge in all new work from the other
2782
branch, automatically determining an appropriate base. If this
2783
fails, you may need to give an explicit base.
2784
2785
Merge will do its best to combine the changes in two branches, but there
2786
are some kinds of problems only a human can fix. When it encounters those,
2787
it will mark a conflict. A conflict means that you need to fix something,
2788
before you should commit.
2789
2790
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2791
2792
If there is no default branch set, the first merge will set it. After
2793
that, you can omit the branch to use the default. To change the
2794
default, use --remember. The value will only be saved if the remote
2795
location can be accessed.
2796
2797
The results of the merge are placed into the destination working
2798
directory, where they can be reviewed (with bzr diff), tested, and then
2799
committed to record the result of the merge.
2800
2801
merge refuses to run if there are any uncommitted changes, unless

--force is given.

Giving a list of files will revert only those files. Otherwise, all files
3162
will be reverted. If the revision is not specified with '--revision', the
3163
last committed revision is used.
3164
3165
To remove only some changes, without reverting to a prior version, use
3166
merge instead. For example, "merge . --revision -2..-3" will remove the
3167
changes introduced by -2, without affecting the changes introduced by -1.
3168
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
3169
3170
By default, any files that have been manually changed will be backed up
3171
first. (Files changed only by merge are not backed up.) Backup files have
3172
'.~#~' appended to their name, where # is a number.
3173
3174
When you provide files, you can use their current pathname or the pathname
3175
from the target revision. So you can use revert to "undelete" a file by
3176
name. If you name a directory, all the contents of that directory will be
3177
reverted.

Any files that have been newly added since that revision will be deleted,

3182
3183
The working tree contains a list of pending merged revisions, which will
3184
be included as parents in the next commit. Normally, revert clears that
3185
list as well as reverting the files. If any files are specified, revert
3186
leaves the pending merge list alone and reverts only the files. Use "bzr
3187
revert ." in the tree root to revert all files but keep the merge record,

"""Mail or create a merge-directive for submiting changes.
4042
4043
A merge directive provides many things needed for requesting merges:
4044
4045
* A machine-readable description of the merge to perform
4046
4047
* An optional patch that is a preview of the changes requested
4048
4049
* An optional bundle of revision data, so that the changes can be applied
4050
directly from the merge directive, without retrieving data from a
4051
branch.
4052
4053
If --no-bundle is specified, then public_branch is needed (and must be
4054
up-to-date), so that the receiver can perform the merge using the
4055
public_branch. The public_branch is always included if known, so that
4056
people can check it later.
4057
4058
The submit branch defaults to the parent, but can be overridden. Both
4059
submit branch and public branch will be remembered if supplied.
4060
4061
If a public_branch is known for the submit_branch, that public submit
4062
branch is used in the merge instructions. This means that a local mirror
4063
can be used as your actual submit branch, once you have set public_branch
4064
for that mirror.
4065
4066
Mail is sent using your preferred mail program. This should be transparent
4067
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4068
If the preferred client can't be found (or used), your editor will be used.
4069
4070
To use a specific mail program, set the mail_client configuration option.
4071
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4072
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4073
generic options are "default", "editor", "mapi", and "xdg-email".
4074
4075
If mail is being sent, a to address is required. This can be supplied
4076
either on the commandline, by setting the submit_to configuration
4077
option in the branch itself or the child_submit_to configuration option
4078
in the submit branch.
4079
4080
Two formats are currently supported: "4" uses revision bundle format 4 and
4081
merge directive format 2. It is significantly faster and smaller than
4082
older formats. It is compatible with Bazaar 0.19 and later. It is the
4083
default. "0.9" uses revision bundle format 0.9 and merge directive
4084
format 1. It is compatible with Bazaar 0.12 - 0.18.
4085
4086
Merge directives are applied using the merge command or the pull command.

4465
For heavyweight checkouts, this checks that there are no local commits
4466
versus the current bound branch, then it makes the local branch a mirror
4467
of the new location and binds to it.
4468
4469
In both cases, the working tree is updated and uncommitted changes
4470
are merged. The user can commit or revert these as they desire.
4471
4472
Pending merges need to be committed or reverted before using switch.
