    Using "bzr revert --forget-merges", it is possible to apply all of the
 
4126
    changes from a branch in a single revision.  To do this, perform the merge
 
4127
    as desired.  Then doing revert with the "--forget-merges" option will keep
 
4128
    the content of the tree as it was, but it will clear the list of pending
 
4129
    merges.  The next commit will then contain all of the changes that are
 
4130
    present in the other branch, but without any other parent revisions.
 
4131
    Because this technique forgets where these changes originated, it may
 
4132
    cause additional conflicts on later merges involving the same source and

      branch.
4928
5044
 
4929
 
    If --no-bundle is specified, then public_branch is needed (and must be
4930
 
    up-to-date), so that the receiver can perform the merge using the
4931
 
    public_branch.  The public_branch is always included if known, so that
4932
 
    people can check it later.
4933
 
 
4934
 
    The submit branch defaults to the parent, but can be overridden.  Both
4935
 
    submit branch and public branch will be remembered if supplied.
4936
 
 
4937
 
    If a public_branch is known for the submit_branch, that public submit
4938
 
    branch is used in the merge instructions.  This means that a local mirror
4939
 
    can be used as your actual submit branch, once you have set public_branch
4940
 
    for that mirror.
 
5045
    `bzr send` creates a compact data set that, when applied using bzr
 
5046
    merge, has the same effect as merging from the source branch.  
 
5047
    
 
5048
    By default the merge directive is self-contained and can be applied to any
 
5049
    branch containing submit_branch in its ancestory without needing access to
 
5050
    the source branch.
 
5051
    
 
5052
    If --no-bundle is specified, then Bazaar doesn't send the contents of the
 
5053
    revisions, but only a structured request to merge from the
 
5054
    public_location.  In that case the public_branch is needed and it must be
 
5055
    up-to-date and accessible to the recipient.  The public_branch is always
 
5056
    included if known, so that people can check it later.
 
5057
 
 
5058
    The submit branch defaults to the parent of the source branch, but can be
 
5059
    overridden.  Both submit branch and public branch will be remembered in
 
5060
    branch.conf the first time they are used for a particular branch.  The
 
5061
    source branch defaults to that containing the working directory, but can
 
5062
    be changed using --from.
 
5063
 
 
5064
    In order to calculate those changes, bzr must analyse the submit branch.
 
5065
    Therefore it is most efficient for the submit branch to be a local mirror.
 
5066
    If a public location is known for the submit_branch, that location is used
 
5067
    in the merge directive.
 
5068
 
 
5069
    The default behaviour is to send the merge directive by mail, unless -o is
 
5070
    given, in which case it is sent to a file.
4941
5071
 
4942
5072
    Mail is sent using your preferred mail program.  This should be transparent
4943
5073
    on Windows (it uses MAPI).  On Linux, it requires the xdg-email utility.
4945
5075
 
4946
5076
    To use a specific mail program, set the mail_client configuration option.
4947
5077
    (For Thunderbird 1.5, this works around some bugs.)  Supported values for
4948
 
    specific clients are "claws", "evolution", "kmail", "mutt", and
4949
 
    "thunderbird"; generic options are "default", "editor", "emacsclient",
4950
 
    "mapi", and "xdg-email".  Plugins may also add supported clients.
 
5078
    specific clients are "claws", "evolution", "kmail", "mail.app" (MacOS X's
 
5079
    Mail.app), "mutt", and "thunderbird"; generic options are "default",
 
5080
    "editor", "emacsclient", "mapi", and "xdg-email".  Plugins may also add
 
5081
    supported clients.
4951
5082
 
4952
5083
    If mail is being sent, a to address is required.  This can be supplied
4953
5084
    either on the commandline, by setting the submit_to configuration
4962
5093
 
4963
5094
    The merge directives created by bzr send may be applied using bzr merge or
4964
5095
    bzr pull by specifying a file containing a merge directive as the location.
 
5096
 
 
5097
    bzr send makes extensive use of public locations to map local locations into
 
5098
    URLs that can be used by other people.  See `bzr help configuration` to
 
5099
    set them, and use `bzr info` to display them.
