+
+;; Hilit19.el is a customizable highlighting package for Emacs19.  It supports
+;; not only source code highlighting, but also Info, RMAIL, VM, gnus...
+;; Hilit19 knows (or thinks it knows) how to highlight emacs buffers in
+;; about 25 different modes.

+;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;;
+;; GENERAL OVERVIEW
+;;
+;;      This package installs numerous hooks to colorfully highlight your
+;;      source code buffers as well as mail and news buffers.  Most 
+;;      programming languages have predefined highlighting patterns.
+;;	Just load hilit19 and files will be automatically highlighted as
+;;      they're loaded.
+;;
+;;      Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L).
+;;
+;;      If, when you edit the buffer, the coloring gets messed up, just
+;;      redraw and the coloring will be adjusted.  If automatic highlighting
+;;      in the current buffer has been turned off, then typing C-u C-S-l will
+;;	force a rehighlight of the entire buffer.
+;;
+;;      Hilit19 can build faces by examining the names that you give to them
+;;	For example, green/black-bold-italic-underline would be created as
+;;	a face with a green foreground, and a black background, using a 
+;;	bold-italic font...with underlining for good measure.
+;;
+;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;;
+;; SETUP -- In your .emacs:
+;;
+;; 
+;; (cond (window-system
+;;        (setq hilit-mode-enable-list  '(not text-mode)
+;;              hilit-background-mode   'light
+;;              hilit-inhibit-hooks     nil
+;;              hilit-inhibit-rebinding nil)
+;; 
+;;        (require 'hilit19)
+;;        ))
+;; 
+;; If you like font-lock-mode and want to use both packages, then you can
+;; disable hilit for the modes in which you want to use font-lock by listing
+;; said modes in hilit-mode-enable-list.
+;; 
+;;      (hilit-translate type     'RoyalBlue   ; enable highlighting in C/C++
+;;			 string	  nil)         ; disable string highlighting
+;;
+;; To get 100% of the utility of hilit19, you may also have to apply the
+;; patches below for info.el and vm5.33L_19/vm-summary.el
+;;
+;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;;
+;; SETUP -- Are you using the right font for Emacs?
+;;
+;; Emacs cannot properly find bold and italic fonts unless you specify a
+;; verbose X11 font name.  If you specify a font for emacs in your
+;; .Xdefaults, it *MUST* be specified using the long form of the font name.
+;; Here's a good font menu:
+;;
+;; (setq
+;;  x-fixed-font-alist
+;;  '("Font Menu"
+;;    ("Misc"
+;;     ("6x12" "-misc-fixed-medium-r-semicondensed--12-110-75-75-c-60-*-1")
+;;     ("6x13" "-misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-*-1")
+;;     ("lucida 13"

+;; KNOWN BUGS/TO DO LIST/HELP WANTED/APPLY WITHIN
+;;
+;; * unbalanced, unescaped double quote characters can confuse hilit19.
+;;   This will be fixed someday, so don't bug me about it.
+;;
+;; * ALTHOUGH HILIT19 IS FASTER THAN FONT-LOCK-MODE...
+;;   For various reasons, the speed of the package could still stand to be
+;;   improved.  If you care to do a little profiling and make things tighter...
+;;
+;; * hilit-toggle-highlight is flaky when auto-rehighlight is neither t nor nil.
+;;   Does anyone actually USE this?  I think I might just remove it.
+;;
+;; PROJECTS THAT YOU CAN TAKE OVER BECAUSE I DON'T MUCH CARE ABOUT THEM...
+;;
+;; * Moved hilit-wysiwyg-replace here from my version of man.el, this is not
+;;   a bug.  The bug is that I don't have a reverse operation yet...just a
+;;   stub Wysiwyg-anything really belongs in a package of its own.

+;; as you can see, I had two similar problems for Pascal and Icon. In
+;; Pascal, strings are delimited with ' and an embedded quote is doubled,
+;; thus string syntax would be extremely simple. However, if a string
+;; occurs within a comment, the following text is considered a string.
+;; 
+;; In Icon, strings are similar to C ones, but there are also charsets,
+;; delimited with simple quotes. I could not manage to use both regexps at
+;; the same time.
+
+;; The problem I have with my patterns for Icon is that this language has a
+;; string similar constant to the C one (but a string can be cut on several
+;; lines, if terminated by a dash and continued with initial blanks, like
+;; this:
+;;         "This is a somewhat long -
+;;          string, written on three -
+;;          successive lines"
+;; in order to insert a double quote in a string, you have to escape it
+;; with a \), bu also a character set constant (named a charset), which
+;; uses single quotes instead of double ones. It would seem intuitive to
+;; highlight both constants in the same way.

+;; - couldn't see handling the special meaning of the Keyword: poster
+;; - not worth the code space to support the old A news Title: (which

+;;	tower@gnu.org Nov 86
+;; changed C-c C-r key-binding due to rename of news-caesar-buffer-body
+;;	tower@gnu.org 21 Nov 86

+;; restricted call of news-show-all-headers in news-post-news & news-reply
+;;	tower@gnu.org 28 Apr 87
+;; commented out Posting-Front-End to save USENET bytes tower@gnu.org Jul 31 87
