;; Author: Eric S. Raymond <esr@snark.thyrsus.com>
;; Created: 16 Jun 1992
;; Version: 1.0
;; Keywords: help
;; X-Modified-by: Bob Weiner <weiner@mot.com>, 4/18/95, to include Lisp
;;	library directory names in finder-program-info, for fast display of
;;	Lisp libraries and associated commentaries.  Added {v}, finder-view,
;;	and {e}, finder-edit commands for displaying libraries.
;;	
;;	Added user variable, 'finder-abbreviate-directory-list', used to
;;	abbreviate directories before they are saved to finder-program-info.
;;	Such relative directories can be portable from one Emacs installation
;;	to another.  Default value is based upon the value of Emacs'
;;      data-directory variable.

;;; Synched up with: FSF 19.34.

;;; Commentary:

;; This mode uses the Keywords library header to provide code-finding
;; services by keyword.
;;
;; Things to do:
;;    1. Support multiple keywords per search.  This could be extremely hairy;
;; there doesn't seem to be any way to get completing-read to exit on
;; an EOL with no substring pending, which is what we'd want to end the loop.
;;    2. Search by string in synopsis line?
;;    3. Function to check finder-package-info for unknown keywords.
