A limited interface between Pine's address books and PMDF's
    personal alias database has existed since Pine 3.91. When you
    add an address to one of Pine's address books using Pine's
    ADDRESS BOOK menu, it will also be added to your personal alias
    database, overwriting any existing entry of the same name. The
    Pine "nickname" is the alias name used in PMDF's personal alias
    database and the e-mail address is the corresponding value for
    the alias. Adding or deleting Pine's address lists has no effect
    on PMDF's personal alias database.

    When you delete an address in one of Pine's address books, it is
    also deleted from PMDF's personal alias database if present.

    The J command can be used to dump the entire current addressbook
    into your PMDF personal alias database. If no personal alias
    database exists, it will be created.
