-
-;;; Commentary:
-;;    This package provides functions to query CCSO PH/QI nameservers
-;;    through an interactive form or replace inline query strings in
-;;    buffers with appropriately formatted query results (especially
-;;    used to expand email addresses in message buffers).  It also
-;;    interfaces with the BBDB package to let you register entries of
-;;    the CCSO PH/QI directory into your own database.  The CCSO PH/QI
-;;    white pages system was developped at UIUC and is in use in more
-;;    than 300 sites in the world.  The distribution can be found at
-;;    ftp://uiarchive.cso.uiuc.edu/pub/packages/ph Traditionally the
-;;    server is called QI while the client is called PH.
-
-;;; Installation:
-;;    This package uses the custom and widget libraries.  If they are not already 
-;;    installed on your system get them from http://www.dina.kvl.dk/~abraham/custom/
-;;    Then uncomment and add the following to your .emacs file:
-;;      (require 'ph)
-;;      (eval-after-load "message"
-;;                       '(define-key message-mode-map [(control ?c) (tab)] 'ph-expand-inline))
-;;      (eval-after-load "mail"
-;;                       '(define-key mail-mode-map [(control ?c) (tab)] 'ph-expand-inline))
-;;    See the info file for details
-
-;;    This package runs under XEmacs 19.15 or 20 and under Emacs 19.34 and above
-
-;;; Usage:
-;;    - Provided you did the installation as proposed in the above section, 
-;;      inline expansion will be available when you compose an email
-;;      message.  Type the name of somebody recorded in your PH/QI server and hit
-;;      C-c TAB, this will overwrite the name with the corresponding email 
-;;      address
-;;    - M-x ph-customize to customize inline expansion and other features to
-;;      your needs.
-;;    - Look for the Ph submenu in the Tools menu for more.
-;;    See the info file for details.
