  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.
