[Mailman-Developers] New to mailman

1. I was going through ~/runners/lmtp.py in mailman 3 source code and
found a line "from zope.component import getUtility"  but there is no
folder named zope anywhere, am i missing something ?

2. Where are the definition of all the functions of classes defined in
/mailman/interfaces in mailman 3 source code present ?

Thanks.
