Requirements
------------
- dnspython (dnspython.org)
- whelk (seveas.github.com/whelk)
- graphviz (graphviz.org)

For the django app only:
- beanstalkd and beanstalkc (kr.github.com/beanstalkd)
- azuki (seveas.github.com/azuki)
- django (djangoproject.com)

Django app
----------

This is also a django app. To use the django app, make sure this directory and
tracegraph.py are available on your sys.path. Then add 'dnsgraph' to your
INSTALLED_APPS setting and urls.py and run syncdb.

You'll need to run beanstalkd and add its info to your settings.py too:

BEANSTALK_SERVER = {'host': '127.0.0.1', 'port': 11300}

Then run the 'daemon' that does the actual checks in a screen session:

./manage.py dnsgraph_daemon
