Loggerhead, one of the web viewers for Bazaar, can now be installed as a bzr plugin, which makes it easier to get it up and running:

bzr branch lp:loggerhead ~/.bazaar/plugins/loggerhead
cd ~/myproject
bzr serve --http

Then you have a browser for all that project’s history up and running on port 8080.

Loggerhead can still be used in the previous ways, as a standalone daemon or embedded within WSGI.
