"""This is an interface to list-specific membership information. This class should not be instantiated directly, but instead, it should be subclassed for specific adaptation to membership databases. The default MM2.0.x style adaptor is in OldStyleMemberships.py. Through the extend.py mechanism, you can instantiate different membership information adaptors to get info out of LDAP, Zope, other, or any combination of the above. Members have three pieces of identifying information: a unique identifying opaque key (KEY), a lower-cased email address (LCE), and a case-preserved email (CPE) address. Adaptors must ensure that both member keys and lces can uniquely identify a member, and that they can (usually) convert freely between keys and lces. Most methods must accept either a key or an lce, unless specifically documented otherwise. The CPE is always used to calculate the recipient address for a message. Some remote MTAs make a distinction based on localpart case, so we always send messages to the case-preserved address. Note that DNS is case insensitive so it doesn't matter what the case is for the domain part of an email address, although by default, we case-preserve that too. The adaptors must support the readable interface for getting information about memberships, and may optionally support the writeable interface. If they do not, then members cannot change their list attributes via Mailman's web or email interfaces. Updating membership information in that case is the backend's responsibility. Adaptors are allowed to support parts of the writeable interface. For any writeable method not supported, a NotImplementedError exception should be raised.
