    Description:
    The LDAP Data Interchange Format (LDIF) is a common ASCII-text based
    Internet interchange format. Most programs allow you to export data in
    LDIF format and e.g. Netscape and Mozilla store by default their
    Personal Address Book files in this format.
    This import and export filter reads and writes any LDIF version 1 files
    into your KDE Addressbook.
