# This file allows loggerhead to be treated as a plugin for bzr.

#

# XXX: Because loggerhead already contains a loggerhead directory, much of the

# code is going to appear loaded at bzrlib.plugins.loggerhead.loggerhead.

# This seems like the easiest thing, because bzrlib wants the top-level plugin

# directory to be the module, but when it's used as a library people expect

# the source directory to contain a directory called loggerhead.  -- mbp

"""Loggerhead web viewer for Bazaar branches.

This provides a new option "--http" to the "bzr serve" command, that 

starts a web server to browse the contents of a branch.
