#require serve ssl

Proper https client requires the built-in ssl from Python 2.6.

Certificates created with:
 printf '.\n.\n.\n.\n.\nlocalhost\nhg@localhost\n' | \
 openssl req -newkey rsa:512 -keyout priv.pem -nodes -x509 -days 9000 -out pub.pem
Can be dumped with:
 openssl x509 -in pub.pem -text
