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

Launchpad.net provides free Bazaar branch hosting with integrated bug and

specification tracking.

The bzr client (through the plugin called 'launchpad') has special

features to communicate with Launchpad:

    * The launchpad-login command tells Bazaar your Launchpad user name. This

      is then used by the 'lp:' transport to download your branches using

      bzr+ssh://.

    * The 'lp:' transport uses Launchpad as a directory service: for example

      'lp:bzr' and 'lp:python' refer to the main branches of the relevant

      projects and may be branched, logged, etc. You can also use the 'lp:'

      transport to refer to specific branches, e.g. lp:~bzr/bzr/trunk.

    * The 'lp:' bug tracker alias can expand launchpad bug numbers to their

      URLs for use with 'bzr commit --fixes', e.g. 'bzr commit --fixes lp:12345'

      will record a revision property that marks that revision as fixing

      Launchpad bug 12345. When you push that branch to Launchpad it will

      automatically be linked to the bug report.

    * The register-branch command tells Launchpad about the url of a

      public branch.  Launchpad will then mirror the branch, display

      its contents and allow it to be attached to bugs and other

      objects.
