  28 ;;; Commentary:
  29 ;;    This package provides functions to query CCSO PH/QI nameservers
  30 ;;    through an interactive form or replace inline query strings in
  31 ;;    buffers with appropriately formatted query results (especially
  32 ;;    used to expand email addresses in message buffers).  It also
  33 ;;    interfaces with the BBDB package to let you register entries of
  34 ;;    the CCSO PH/QI directory into your own database.  The CCSO PH/QI
  35 ;;    white pages system was developped at UIUC and is in use in more
  36 ;;    than 300 sites in the world.  The distribution can be found at
  37 ;;    ftp://uiarchive.cso.uiuc.edu/pub/packages/ph Traditionally the
  38 ;;    server is called QI while the client is called PH.
  39
  40 ;;; Installation:
  41 ;;    This package uses the custom and widget libraries.  If they are not already
  42 ;;    installed on your system get them from http://www.dina.kvl.dk/~abraham/custom/
  43 ;;    Then uncomment and add the following to your .emacs file:
  44 ;;      (require 'ph)
  45 ;;      (eval-after-load "message"
  46 ;;                       '(define-key message-mode-map [(control ?c) (tab)] 'ph-expand-inline))
  47 ;;      (eval-after-load "mail"
  48 ;;                       '(define-key mail-mode-map [(control ?c) (tab)] 'ph-expand-inline))
  49 ;;    See the info file for details
  50
  51 ;;    This package runs under XEmacs 19.15 or 20 and under Emacs 19.34 and above
  52
  53 ;;; Usage:
  54 ;;    - Provided you did the installation as proposed in the above section,
  55 ;;      inline expansion will be available when you compose an email
  56 ;;      message.  Type the name of somebody recorded in your PH/QI server and hit
  57 ;;      C-c TAB, this will overwrite the name with the corresponding email
  58 ;;      address
  59 ;;    - M-x ph-customize to customize inline expansion and other features to
  60 ;;      your needs.
  61 ;;    - Look for the Ph submenu in the Tools menu for more.
  62 ;;    See the info file for details.
