;;; Commentary:
;;
;; Names are often not recognized by the standard ispell dictionaries.
;; `bbdb-ispell-export' exports the names from your BBDB records to your
;; personal ispell dictionaries.
;; The personal dictionaries are in `bbdb-ispell-dictionary-list'
;; The BBDB fields for this are in `bbdb-ispell-field-list'.
;; Exclude words via `bbdb-ispell-min-word-length' and `bbdb-ispell-ignore-re'.
;;
;; Bugs:
;; Save your personal directories before running this code. I had my
;; dictionary truncated while debugging. It shouldn't happen
;; but better be safe than sorry...
;;
;; See the BBDB info manual for documentation.
