Problems
--------

The server pretty much needs to be rooted at /dweb (see authdb.crk) because
all of the redirects are hard-coded to do this.


Setup
-----

You'll need to set up the following:

    server_salt.data
        This is the server salt file.  It can contain anything and be of any
        length.  This is only used to seed the random number generator.  We
        should replace it with /dev/urandom.
    users.db & cookies.db
        Create an admin user and passord with mkadmin.  Can be any user id.

If you're sending mail, you'll also need a Crash file containing the mailer
configuration:

    mailer {
        domain 'example.com'  # Sender domain.
        api_addr 'user@example.com'  # Address to ssh to to send mail.
    }

The `api_addr` should be an address whose default shell accepts a "send"
command with arguments sender address, recipient addresses (formatted as a
single string parameter with recipients separated by commas) and the message
size.  The command should then read the entire message (the number of bytes
specified in the message size, followed by a newline) from standard input.  It
should then write "ok" (followed by a newline) to standard output.

The Crash file should be specified on the command line after the port number
and root path.

Starting the server
-------------------

    $ crack server.crk

To clear all cookies, you can just delete cookies.db.
