"""Launchpad.net integration plugin for Bazaar.

This plugin provides facilities for working with Bazaar branches that are

hosted on Launchpad (http://launchpad.net).  It provides a directory service 

for referring to Launchpad branches using the "lp:" prefix.  For example,

lp:bzr refers to the Bazaar's main development branch and

lp:~username/project/branch-name can be used to refer to a specific branch.

This plugin provides a bug tracker so that "bzr commit --fixes lp:1234" will

record that revision as fixing Launchpad's bug 1234.

The plugin also provides the following commands:

    launchpad-login: Show or set the Launchpad user ID

    launchpad-open: Open a Launchpad branch page in your web browser

    lp-propose-merge: Propose merging a branch on Launchpad

    launchpad-mirror: Ask Launchpad to mirror a branch now

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.
