__doc__ = """Merge hook for bzr's NEWS file.

To enable this plugin, add a section to your branch.conf or location.conf
like::

    [/home/user/code/bzr]
    news_merge_files = NEWS

The news_merge_files config option takes a list of file paths, separated by
commas.

Limitations:

* if there's a conflict in more than just bullet points, this doesn't yet know
  how to resolve that, so bzr will fallback to the default line-based merge.
