Addressbook

   You can have one or more addressbooks in Pine. In addition to a
   personal addressbook, one or more global, read-only addressbooks
   can be set up (for sharing between multiple users). The names
   of your personal addressbooks are specified in the Pine resource
   file by the ADDRESS-BOOK option. Normally, this option is set
   and modified from within Pine by using the SETUP menu and then
   selecting the Addressbook menu; it can, however, also be set by
   manually editing the Pine resource file. The built-in default
   file name used for an addressbook PMDF_INIT:PINE.ADDRESSBOOK.
   A "lookup" file is used to speed access to the addressbook. The
   lookup file has the same name as the addressbook, with -LU as
   suffix; e.g., PMDF_INIT:PINE.ADDRESSBOOK-LU. The lookup file
   is generated automatically by Pine. Global addressbooks can be
   specified using the GLOBAL-ADDRESS-BOOK option.
