Description:

Turba is a complete basic contact management application. SQL, LDAP,
and Horde Preferences backends are available and are well tested. You
can define the fields in your address books in a very flexible way,
just by changing the config files. You can import/export from/to Pine,
Mulberry, CSV, TSV, and vCard contacts. You can create distribution
lists from your addressbooks, which are handled transparently by IMP
and other Horde applications. And there are Horde API functions to add
and search for contacts.
