+;; History:
+;;
+;; 0.02--1.00:
+;; - Changed name from turbo-prop to fast-lock. Automagic for font-lock only
+;; - Made `fast-lock-mode' a minor mode, like G. Dinesh Dutt's fss-mode
+;; 1.00--1.01:
+;; - Turn on `fast-lock-mode' only if `buffer-file-name' or `interactive-p'
+;; - Made `fast-lock-file-name' use `buffer-name' if `buffer-file-name' is nil
+;; - Moved save-all conditions to `fast-lock-save-cache'
+;; - Added `fast-lock-save-text-properties' to `kill-buffer-hook'
+;; 1.01--2.00: complete rewrite---not worth the space to document
+;; - Changed structure of text properties cache and threw out file mod checks
+;; 2.00--2.01:
+;; - Made `condition-case' forms understand `quit'.
+;; - Made `fast-lock' require `font-lock'
+;; - Made `fast-lock-cache-name' chase links (from Ben Liblit)
+;; 2.01--3.00:
+;; - Changed structure of cache to include `font-lock-keywords' (from rms)
+;; - Changed `fast-lock-cache-mechanisms' to `fast-lock-cache-directories'
+;; - Removed `fast-lock-read-others'
+;; - Made `fast-lock-read-cache' ignore cache owner
+;; - Made `fast-lock-save-cache-external' create cache directory
+;; - Made `fast-lock-save-cache-external' save `font-lock-keywords'
+;; - Made `fast-lock-cache-data' check `font-lock-keywords'
+;; 3.00--3.01: incorporated port of 2.00 to Lucid, made by Barry Warsaw
+;; - Package now provides itself
+;; - Lucid: Use `font-lock-any-extents-p' for `font-lock-any-properties-p'
+;; - Lucid: Use `list-faces' for `face-list'
+;; - Lucid: Added `set-text-properties'
+;; - Lucid: Made `turn-on-fast-lock' pass 1 not t to `fast-lock-mode'
+;; - Removed test for `fast-lock-mode' from `fast-lock-read-cache'
+;; - Lucid: Added Lucid-specific `fast-lock-get-face-properties'
+;; 3.01--3.02: now works with Lucid Emacs, thanks to Barry Warsaw
+;; - Made `fast-lock-cache-name' map ":" to ";" for OS/2 (from Serganova Vera)
+;; - Made `fast-lock-cache-name' use abbreviated file name (from Barry Warsaw)
+;; - Lucid: Separated handlers for `error' and `quit' for `condition-case'
+;; 3.02--3.03:
+;; - Changed `fast-lock-save-cache-external' to `fast-lock-save-cache-data'
+;; - Lucid: Added Lucid-specific `fast-lock-set-face-properties'
+;; 3.03--3.04:
+;; - Corrected `subrp' test of Lucid code
+;; - Replaced `font-lock-any-properties-p' with `text-property-not-all'
+;; - Lucid: Made `fast-lock-set-face-properties' put `text-prop' on extents

+;; - Made `fast-lock-cache-directory' to return a usable cache file directory
+;; 3.04--3.05:
+;; - Lucid: Fix for XEmacs 19.11 `text-property-not-all'
+;; - Replaced `subrp' test of Lucid code with `emacs-version' `string-match'
+;; - Made `byte-compile-warnings' omit `unresolved' on compilation
+;; - Made `fast-lock-save-cache-data' use a buffer (from Rick Sladkey)
+;; - Reverted to old `fast-lock-get-face-properties' (from Rick Sladkey)
+;; 3.05--3.06: incorporated hack of 3.03, made by Jonathan Stigelman (Stig)
+;; - Reverted to 3.04 version of `fast-lock-get-face-properties'
