"""This server extends BaseHTTPServer and SimpleHTTPServer thusly:
1. One thread per connection.
2. Generates directory listings.

In addition, it has the following properties:
1. Works over HTTPS only.
2. Displays SSL handshaking and SSL session info.
3. Performs SSL renegotiation when a magic url is requested.

TODO:
1. Cache stat() of directory entries.
2. Fancy directory indexing.
3. Interface ZPublisher.
