This module set does not do anything by itself. It provides the framework for contact sources to be used in Cypht. Currently there are 3 contact sources supported:
- local contacts: Basic contact support locally within Cypht
- LDAP contacts: Uses an LDAP server to access/manage contacts
- Gmail contacts: Read-only access to contacts from Gmail accounts
One or all of those module sets can be enabled with this one to add contact support for that source. Some work has been done to add CardDav contact support, however there is much left to do.
