309
In non-recursive mode, all the named items are added, regardless
310
of whether they were previously ignored. A warning is given if
311
any of the named files are already versioned.
312
313
In recursive mode (the default), files are treated the same way
314
but the behaviour for directories is different. Directories that
315
are already versioned do not give a warning. All directories,
316
whether already versioned or not, are searched for files or
317
subdirectories that are neither versioned or ignored, and these
318
are added. This search proceeds recursively into versioned
319
directories. If no names are given '.' is assumed.
320
321
Therefore simply saying 'bzr add' will version all files that
322
are currently unknown.
323
324
Adding a file whose parent directory is not versioned will
325
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
327
get added when you add a file in the directory.

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

add them.
331
332
--file-ids-from will try to use the file ids from the supplied path.
333
It looks up ids trying to find a matching parent directory with the
334
same filename, and then by pure path. This option is rarely needed
335
but can be useful when adding the same logical file into two
336
branches that will be merged later (without showing the two different
337
adds as a conflict). It is also useful when merging another project

2017
given, try to find the format with the extension. If no extension
2018
is found exports to a directory (equivalent to --format=dir).

If root is supplied, it will be used as the root directory inside
2021
container formats (tar, zip, etc). If it is not supplied it will default

to the exported filename. The root option has no effect for 'dir' format.

If branch is omitted then the branch containing the current working

directory will be used.

If arguments are given, they are regular expressions that say which tests

2426
not run.
2427
2428
Alternatively if --first is given, matching tests are run first and then

all other tests are run. This is useful if you have been working in a
2430
particular area, but want to make sure nothing else was broken.
2431
2432
If --exclude is given, tests that match that regular expression are
2433
excluded, regardless of whether they match --first or not.
2434
2435
To help catch accidential dependencies between tests, the --randomize
2436
option is useful. In most cases, the argument used is the word 'now'.
2437
Note that the seed used for the random number generator is displayed
2438
when this option is used. The seed can be explicitly passed as the
2439
argument to this option if required. This enables reproduction of the
2440
actual ordering used if and when an order sensitive problem is encountered.
2441
2442
If --list-only is given, the tests that would be run are listed. This is
2443
useful when combined with --first, --exclude and/or --randomize to
2444
understand their impact. The test harness reports "Listed nn tests in ..."

If the global option '--no-plugins' is given, plugins are not loaded

2614
2615
The branch is the branch you will merge from. By default, it will merge
2616
the latest revision. If you specify a revision, that revision will be
2617
merged. If you specify two revisions, the first will be used as a BASE,
2618
and the second one as OTHER. Revision numbers are always relative to the
2619
specified branch.
2620
2621
By default, bzr will try to merge in all new work from the other
2622
branch, automatically determining an appropriate base. If this
2623
fails, you may need to give an explicit base.
2624
2625
Merge will do its best to combine the changes in two branches, but there
2626
are some kinds of problems only a human can fix. When it encounters those,
2627
it will mark a conflict. A conflict means that you need to fix something,
2628
before you should commit.
2629
2630
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2631
2632
If there is no default branch set, the first merge will set it. After
2633
that, you can omit the branch to use the default. To change the
2634
default, use --remember. The value will only be saved if the remote
2635
location can be accessed.
2636
2637
The results of the merge are placed into the destination working
2638
directory, where they can be reviewed (with bzr diff), tested, and then
2639
committed to record the result of the merge.
2640
2641
merge refuses to run if there are any uncommitted changes, unless
2642
--force is given.
