Now developing on Ubuntu 12.04 with Python 2.7. Use symbolic links for media, so add media/banners to .hgignore. I had a syntax error in banner_tags.py that only Python 2.7 caught. For local development, read database name from SECRETS.

div.potd-details {
    text-align: center;
}
div.potd-details p.caption {
    font-weight: bold;
}
div.potd-details p.details {
    font-style: italic;
    font-size: smaller;
}
