+;; Client for the CCSO directory system (aka PH/QI)|
+;; 27-May-1997|Version $Revision: 1.2 $|ftp://(Not Available)
+;;    This package provides functions to query CCSO 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 directory into your own database.
+;;    The CCSO 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))
+;;    This package should run under XEmacs 19.15 or 20 as well as 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.
