    <h1>Database not populated</h1>

    <p>Before you can run PeopleAggregator, you need to populate the database by running the script <code><?php 
            echo $path_prefix;
            ?>
/db/PeepAgg.mysql</code> on your database.  You can do it in the MySQL console like this:</p>

    <pre><i>user</i>@<i>server</i>:<?php 
            echo $path_prefix;
            ?>
$ <b>mysql -u <i>username</i> -p</b>
Enter password: <b><i>password</i></b>

Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
