;;; Commentary:
;;{{{  Introduction

;;;This module implements user customizable pronunciation dictionaries
;;;for emacspeak. Custom pronunciations can be defined per file, per
;;;directory and/or per major mode. Emacspeak maintains a persistent
;;;user dictionary upon request and loads these in new emacspeak
;;;sessions. This module implements the user interface to the custom
;;;dictionary as well as providing the internal API used by the rest
;;;of emacspeak in using the dictionary.
;;;Algorithm:

;;;The persistent dictionary is a hash table where the hash keys are
;;;filenames, directory names, or major-mode names. The hash values
;;;are association lists defining the dictionary. Users of this module
;;;can retrieve a dictionary made up of all applicable association
;;;lists for a given file.
