Commit 11e2a74f changed the line to
remove the '-rc' flag but seems to have accidentally removed the dot
character at the same time.

Users can now define their own sections and ordering. For example

    import_heading_stdlib = Standard Library
    import_heading_thirdparty = Third Party
    import_heading_firstparty = First Party
    import_heading_django = Django
    import_heading_pandas = Pandas
    known_django = django
    known_pandas = pandas,numpy
    known_first_party = p24,p24.imports._VERSION
    sections = FUTURE,STDLIB,DJANGO,THIRDPARTY,PANDAS,FIRSTPARTY,LOCALFOLDER

would create two new sections with the specified known modules.

    # Standard Library
    import os
    import p24.imports._argparse as argparse
    import p24.imports._subprocess as subprocess
    import sys

    # Django
    from django.conf import settings
    from django.db import models

    # Third Party
    from bottle import Bottle, redirect, response, run

    # Pandas
    import numpy as np
    import pandas as pd

    # First Party
    import p24.imports._VERSION as VERSION
    import p24.shared.media_wiki_syntax as syntax

These changes enable any user that installs `isort` to check his source
code from setup.py with the command `python setup.py isort`

I also checked isort package code with his command in tox and travis.

Acknowledgements: this is mostly inspired by flake8 setuptools integration,
see [flake8 doc](http://flake8.readthedocs.org/en/2.2.3/setuptools.html)

This allows them to be grouped with __future__ imports.
