"""Simple parser for bzr's NEWS file.

Simple as this is, it's a bit over-powered for news_merge's needs, which only
20
cares about 'bullet' and 'everything else'.
22
This module can be run as a standalone Python program; pass it a filename and
23
it will print the parsed form of a file (a series of 2-tuples, see
24
simple_parse's docstring).

"""Returns blocks, where each block is a 2-tuple (kind, text).
31
:kind: one of 'heading', 'release', 'section', 'empty' or 'text'.
32
:text: a str, including newlines.

blocks = content.split('\n\n')
36
if block.startswith('###'):
37
