"""Simple parser for bzr's NEWS file.
Simple as this is, it's a bit over-powered for news_merge's needs, which only
cares about 'bullet' and 'everything else'.
This module can be run as a standalone Python program; pass it a filename and
it will print the parsed form of a file (a series of 2-tuples, see
simple_parse's docstring).
