of Bazaar in a convenient fashion. Plugins need to fit seamlessly into
the core program, yet are often developed and shipped separately. In
this talk David Allouche will demonstrate Bazaar, some of the existing
plugins for Bazaar, and show how to write a plugin. Robert Collins will
talk about the plugin system, what we wanted to achieve with it, what it
has done to and for Bazaar.
