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.

--dry-run will show which files would be added, but not actually
331
add them.
332

--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

2557
If arguments are given, they are regular expressions that say which tests
2558
should run. Tests matching any expression are run, and other tests are
2559
not run.
2560
2561
Alternatively if --first is given, matching tests are run first and then
2562
all other tests are run. This is useful if you have been working in a
2563
particular area, but want to make sure nothing else was broken.
2564
2565
If --exclude is given, tests that match that regular expression are
2566
excluded, regardless of whether they match --first or not.
2567
2568
To help catch accidential dependencies between tests, the --randomize
2569
option is useful. In most cases, the argument used is the word 'now'.
2570
Note that the seed used for the random number generator is displayed
2571
when this option is used. The seed can be explicitly passed as the
2572
argument to this option if required. This enables reproduction of the
2573
actual ordering used if and when an order sensitive problem is encountered.
2574
2575
If --list-only is given, the tests that would be run are listed. This is
2576
useful when combined with --first, --exclude and/or --randomize to
2577
understand their impact. The test harness reports "Listed nn tests in ..."
2578
instead of "Ran nn tests in ..." when list mode is enabled.
2579
2580
If the global option '--no-plugins' is given, plugins are not loaded
2581
before running the selftests. This has two effects: features provided or
2582
modified by plugins will not be tested, and tests provided by plugins will
2583
not be run.
2584
2585
Tests that need working space on disk use a common temporary directory,
2586
typically inside $TMPDIR or /tmp.
2587
2588
:Examples:
2589
Run only tests relating to 'ignore'::
2590

bzr selftest ignore

2765
2766
The branch is the branch you will merge from. By default, it will merge
2767
the latest revision. If you specify a revision, that revision will be
2768
merged. If you specify two revisions, the first will be used as a BASE,
2769
and the second one as OTHER. Revision numbers are always relative to the
2770
specified branch.
2771
2772
By default, bzr will try to merge in all new work from the other
2773
branch, automatically determining an appropriate base. If this
2774
fails, you may need to give an explicit base.
2775
2776
Merge will do its best to combine the changes in two branches, but there
2777
are some kinds of problems only a human can fix. When it encounters those,
2778
it will mark a conflict. A conflict means that you need to fix something,
2779
before you should commit.
2780
2781
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2782
2783
If there is no default branch set, the first merge will set it. After
2784
that, you can omit the branch to use the default. To change the
2785
default, use --remember. The value will only be saved if the remote
2786
location can be accessed.
2787
2788
The results of the merge are placed into the destination working
2789
directory, where they can be reviewed (with bzr diff), tested, and then
2790
committed to record the result of the merge.
2791

--force is given.

Giving a list of files will revert only those files. Otherwise, all files
3157
will be reverted. If the revision is not specified with '--revision', the
3158
last committed revision is used.
3159
3160
To remove only some changes, without reverting to a prior version, use
3161
merge instead. For example, "merge . --revision -2..-3" will remove the
3162
changes introduced by -2, without affecting the changes introduced by -1.
3163
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
3164
3165
By default, any files that have been manually changed will be backed up
3166
first. (Files changed only by merge are not backed up.) Backup files have
3167
'.~#~' appended to their name, where # is a number.
3168
3169
When you provide files, you can use their current pathname or the pathname
3170
from the target revision. So you can use revert to "undelete" a file by
3171
name. If you name a directory, all the contents of that directory will be
3172
reverted.
3173
3174
Any files that have been newly added since that revision will be deleted,

will not be deleted.
3177
3178
The working tree contains a list of pending merged revisions, which will
3179
be included as parents in the next commit. Normally, revert clears that
3180
list as well as reverting the files. If any files are specified, revert
3181
leaves the pending merge list alone and reverts only the files. Use "bzr
3182
revert ." in the tree root to revert all files but keep the merge record,

"""Mail or create a merge-directive for submiting changes.
4038
4039
A merge directive provides many things needed for requesting merges:
4040
4041
* A machine-readable description of the merge to perform
4042
4043
* An optional patch that is a preview of the changes requested
4044
4045
* An optional bundle of revision data, so that the changes can be applied
4046
directly from the merge directive, without retrieving data from a
4047
branch.
4048
4049
If --no-bundle is specified, then public_branch is needed (and must be
4050
up-to-date), so that the receiver can perform the merge using the
4051
public_branch. The public_branch is always included if known, so that
4052
people can check it later.
4053
4054
The submit branch defaults to the parent, but can be overridden. Both
4055
submit branch and public branch will be remembered if supplied.
4056
4057
If a public_branch is known for the submit_branch, that public submit
4058
branch is used in the merge instructions. This means that a local mirror
4059
can be used as your actual submit branch, once you have set public_branch
4060
for that mirror.
4061
4062
Mail is sent using your preferred mail program. This should be transparent
4063
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4064
If the preferred client can't be found (or used), your editor will be used.
4065
4066
To use a specific mail program, set the mail_client configuration option.
4067
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4068
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4069
generic options are "default", "editor", "mapi", and "xdg-email".
4070
4071
If mail is being sent, a to address is required. This can be supplied
4072
either on the commandline, by setting the submit_to configuration
4073
option in the branch itself or the child_submit_to configuration option
4074
in the submit branch.
4075
4076
Two formats are currently supported: "4" uses revision bundle format 4 and
4077
merge directive format 2. It is significantly faster and smaller than
4078
older formats. It is compatible with Bazaar 0.19 and later. It is the
4079
default. "0.9" uses revision bundle format 0.9 and merge directive
4080
format 1. It is compatible with Bazaar 0.12 - 0.18.

Pending merges need to be committed or reverted before using switch.
