    This command lists a bzr branch in the directory of branches on

    launchpad.net.  Registration allows the branch to be associated with

    bugs or specifications.

    Before using this command you must register the project to which the

    branch belongs, and create an account for yourself on launchpad.net.

    arguments:

        public_url: The publicly visible url for the branch to register.

                    This must be an http or https url (which Launchpad can read

                    from to access the branch). Local file urls, SFTP urls, and

                    bzr+ssh urls will not work.

                    If no public_url is provided, bzr will use the configured

                    public_url if there is one for the current branch, and

                    otherwise error.
