You'll need Python 3 and some other Python packages. I recommend using virtualenv
(http://virtualenv.org) to create a local Python environment. Then you can do
something like

    $ virtualenv -p python3 myenv
    $ myenv/bin/pip install bottle pycrypto requests

Now, whenever you seen "python3" below, write "myenv/bin/python" instead.

To generate a DAGA authentication context run:

    $ python3 gencontext.py a_context

This creates a random DAGA context and dumps a lot of data into the directory
a_context. You can change the number of servers and clients with the -s and -c
options respectively.

The run DAGA servers locally, use the server_supervisor script:

    $ python3 server_supervisor.py a_context

Then in another terminal, you can perform a client authentication by running

    $ python3 daga_client.py ctx/context.json ctx/client-0.json

Hopefully that will not fail.
