-;;; Commentary:
-
-;; Quickstart Installation:
-;; ========================
-;;
-;; To get this to work, make emacs execute the line
-;;
-;; (require 'todo-mode) ;; load the TODO package
-;;
-;; You may now enter new items by typing "M-x todo-insert-item", or enter
-;; your the TODO list file by typing "M-x todo-show".
-;;
-;; The TODO list file has a special format and some auxiliary information,
-;; which will be added by the todo-show function if it attempts to visit
-;; an un-initialised file. Hence it is recommended to use the todo-show
-;; function for the first time, in order to initialise the file, but it
-;; is not necessary afterwards.
-;;
-;; As these commands are quite long to type, I would recommend the addition
-;; of two bindings to your to your global keymap. I personally have the
-;; following in my initialisation file:
-;;
-;; (global-set-key "\C-ct" 'todo-show) ;; switch to TODO buffer
-;; (global-set-key "\C-ci" 'todo-insert-item) ;; insert new item
-;;
-;; Note, however, that this recommendation has prompted some criticism,
-;; since the keys C-c LETTER are reserved for user functions. I believe
-;; my recommendation is acceptable, since the Emacs Lisp Manual *Tips*
-;; section also details that the mode itself should not bind any functions
-;; to those keys. The express aim of the above two bindings is to work
-;; outside the mode, which doesn't need the show function and offers
-;; a different binding for the insert function. They serve as shortcuts
-;; and are not even needed (since the TODO mode will be entered by
-;; visiting the TODO file, and later by switching to its buffer).
-;;
-;;
-;;
-;; Pre-Requisites
-;; ==============
-;;
-;; This package will require the following packages to be available on
-;; the load-path:
-;; - time-stamp
-;; - easymenu
-;;
-;;
-;;
-;; Description:
-;; ============
-;;
-;; TODO is a major mode for EMACS which offers functionality to treat
-;; most lines in one buffer as a list of items one has to do. There
-;; are facilities to add new items, which are categorised, to edit or
-;; even delete items from the buffer. The buffer contents are currently
-;; compatible with the diary, so that the list of todo-items will show
-;; up in the FANCY diary mode.
-;;
-;; Notice: Besides the major mode, this file also exports the function
-;; "todo-show" which will change to the one specific TODO file that has
-;; been specified in the todo-file-do variable. If this file does not
-;; conform to the TODO mode conventions, the todo-show function will add
-;; the appropriate header and footer. I don't anticipate this to cause
-;; much grief, but be warned, in case you attempt to read a plain text file.
-;;
-;;
-;;
-;; Operation:
-;; ==========
-;;
-;; You will have the following facilities available:
-;;
-;; M-x todo-show will enter the todo list screen, here type
-;;
-;; + to go to next category
-;; - to go to previous category
-;; e to edit the current entry
-;; f to file the current entry, including a
-;; comment and timestamp
-;; i to insert a new entry
-;; k to kill the current entry
-;; l to lower the current entry's priority
-;; n for the next entry
-;; p for the previous entry
-;; q to save the list and exit the buffer
-;; r to raise the current entry's priority
-;; s to save the list
-;;
-;; When you add a new entry, you are asked for the text and then for the
-;; category. I for example have categories for things that I want to do
-;; in the office (like mail my mum), that I want to do in town (like buy
-;; cornflakes) and things I want to do at home (move my suitcases). The
-;; categories can be selected with the cursor keys and if you type in the
-;; name of a category which didn't exist before, an empty category of the
-;; desired name will be added and filled with the new entry.
-;;
-;;
-;;
-;; Configuration:
-;; ==============
-;;
-;; --- todo-prefix
-;;
-;; I would like to recommend that you use the prefix "*/*" (by
-;; leaving the variable 'todo-prefix' untouched) so that the diary
-;; displays each entry every day.
-;;
-;; To understand what I mean, please read the documentation that goes
-;; with the calendar since that will tell you how you can set up the
-;; fancy diary display and use the #include command to include your
-;; todo list file as part of your diary.
-;;
-;; If you have the diary package set up to usually display more than
-;; one day's entries at once, consider using
-;; "&%%(equal (calendar-current-date) date)"
-;; as the value of `todo-prefix'. Please note that this may slow down
-;; the processing of your diary file some.
-;;
-;;
-;; --- todo-file-do
-;;
-;; This variable is fairly self-explanatory. You have to store your TODO
-;; list somewhere. This variable tells the package where to go and find
-;; this file.
-;;
-;;
-;; --- todo-file-done
-;;
-;; Even when you're done, you may wish to retain the entries. Given
-;; that they're timestamped and you are offered to add a comment, this
-;; can make a useful diary of past events. It will even blend in with
-;; the EMACS diary package. So anyway, this variable holds the name
-;; of the file for the filed todo-items.
-;;
-;;
-;; --- todo-mode-hook
-;;
-;; Just like other modes, too, this mode offers to call your functions
-;; before it goes about its business. This variable will be inspected
-;; for any functions you may wish to have called once the other TODO
-;; mode preparations have been completed.
-;;
-;;
-;; --- todo-insert-treshold
-;;
-;; Another nifty feature is the insertion accuracy. If you have 8 items
-;; in your TODO list, then you may get asked 4 questions by the binary
-;; insertion algorithm. However, you may not really have a need for such
-;; accurate priorities amongst your TODO items. If you now think about
-;; the binary insertion halfing the size of the window each time, then
-;; the threshhold is the window size at which it will stop. If you set
-;; the threshhold to zero, the upper and lower bound will coincide at the
-;; end of the loop and you will insert your item just before that point.
-;; If you set the threshhold to i.e. 8, it will stop as soon as the window
-;; size drops below that amount and will insert the item in the approximate
-;; centre of that window. I got the idea for this feature after reading
-;; a very helpful e-mail reply from Trey Jackson <trey@cs.berkeley.edu>
-;; who corrected some of my awful coding and pointed me towards some good
-;; reading. Thanks Trey!
-;;
-;;
-;;
-;;
-;; Things to do:
-;; =============
-;;
-;; - licence / version function
-;; - export to diary file
-;; - todo-report-bug
-;; - GNATS support
-;; - add idea from Urban Boquist <boquist@cs.chalmers.se>: multi-line-entries
-;; - 'e' opens buffer for multi-line entry
-;; - elide multiline
-;; - rewrite complete package to store data as lisp objects and have
-;; display modes for display, for diary export, etc.
-;;
-;;
-;;
-;; History and Gossip:
-;; ===================
-;;
-;; Many thanks to all the ones who have contributed to the evolution of this
-;; package! I hope I have listed all of you somewhere in the documentation
-;; or at least in the RCS history!
-;;
-;; Enjoy this package and express your gratitude by sending nice things
-;; to my parents' address!

-;;; Change Log:
-
-;; $Log: todo-mode.el,v $
-;; Revision 1.15 1997/10/14 22:22:35 os10000
-;; Added string-split (which I stole from ediff-util), changed
-;; pop-to-buffer to switch-to-buffer and added message on how
-;; to exit the multi-line-edit mode.
-;;
-;; Revision 1.14 1997/10/09 09:24:50 os10000
-;; Harald Meland <harald.meland@usit.uio.no> asked for
-;; the latest version, got 1.13, and returned this.
-;; He writes:
-;;
-;; Thanks a lot for the new version of todo-mode.el. As you will see I
-;; have messed it up a bit, hopefully for the better -- I don't like
-;; short, cryptic names for variables and functions, so I renamed most of
-;; them, and `defalias'ed the old function names. I hope you don't mind
-;; too much, I just kinda couldn't stop myself.
-;;
-;; Additionally, I included some support for multiline entries, cleaned
-;; up (IMHO :) a lot of the code, included completion-support for which
-;; category to install a new entry in, and possibly some other changes I
-;; can't remember :)
-;;
-;; It's getting rather late, and I have just done some preliminary
-;; testing on whether all of this really works, but so far it looks
-;; good.

+
+;;; Commentary:
+
+;; Mode Description
+;;
+;; TODO is a major mode for EMACS which offers functionality to
+;; treat most lines in one buffer as a list of items one has to
+;; do. There are facilities to add new items, which are
+;; categorised, to edit or even delete items from the buffer.
+;; The buffer contents are currently compatible with the diary,
+;; so that the list of todo-items will show up in the FANCY diary
+;; mode.
+;;
+;; Notice: Besides the major mode, this file also exports the
+;; function `todo-show' which will change to the one specific
+;; TODO file that has been specified in the todo-file-do
+;; variable. If this file does not conform to the TODO mode
+;; conventions, the todo-show function will add the appropriate
+;; header and footer. I don't anticipate this to cause much
+;; grief, but be warned, in case you attempt to read a plain text
+;; file.
+;;
+;; Preface, Quickstart Installation
+;;
+;; To get this to work, make emacs execute the line
+;;
+;; (autoload 'todo-mode "todo-mode"
+;; "Major mode for editing TODO lists." t)
+;; (autoload 'todo-show "todo-mode"
+;; "Show TODO items." t)
+;; (autoload 'todo-insert-item "todo-mode"
+;; "Add TODO item." t)
+;;
+;; You may now enter new items by typing "M-x todo-insert-item",
+;; or enter your TODO list file by typing "M-x todo-show".
+;;
+;; The TODO list file has a special format and some auxiliary
+;; information, which will be added by the todo-show function if
+;; it attempts to visit an un-initialised file. Hence it is
+;; recommended to use the todo-show function for the first time,
+;; in order to initialise the file, but it is not necessary
+;; afterwards.
+;;
+;; As these commands are quite long to type, I would recommend
+;; the addition of two bindings to your to your global keymap. I
+;; personally have the following in my initialisation file:
+;;
+;; (global-set-key "\C-ct" 'todo-show) ;; switch to TODO buffer
+;; (global-set-key "\C-ci" 'todo-insert-item) ;; insert new item
+;;
+;; Note, however, that this recommendation has prompted some
+;; criticism, since the keys C-c LETTER are reserved for user
+;; functions. I believe my recommendation is acceptable, since
+;; the Emacs Lisp Manual *Tips* section also details that the
+;; mode itself should not bind any functions to those keys. The
+;; express aim of the above two bindings is to work outside the
+;; mode, which doesn't need the show function and offers a
+;; different binding for the insert function. They serve as
+;; shortcuts and are not even needed (since the TODO mode will be
+;; entered by visiting the TODO file, and later by switching to
+;; its buffer).
+;;
+;; If you are an advanced user of this package, please consult
+;; the whole source code for autoloads, because there are several
+;; extensions that are not explicitly listed in the above quick
+;; installation.
+;;
+;; Version
+;;
+;; Which version of todo-mode.el does this documentation refer to?
+;;
+;; $Id: todo-mode.el,v 1.45 2001/07/05 13:44:53 gerd Exp $
+;;
+;; Pre-Requisites
+;;
+;; This package will require the following packages to be
+;; available on the load-path:
+;;
+;; time-stamp
+;; easymenu
+;;
+;; Operation
+;;
+;; You will have the following facilities available:
+;;
+;; M-x todo-show will enter the todo list screen, here type
+;;
+;; + to go to next category
+;; - to go to previous category
+;; d to file the current entry, including a
+;; comment and timestamp
+;; e to edit the current entry
+;; E to edit a multi-line entry
+;; f to file the current entry, including a
+;; comment and timestamp
+;; i to insert a new entry, with prefix, omit category
+;; I to insert a new entry at current cursor position
+;; j jump to category
+;; k to kill the current entry
+;; l to lower the current entry's priority
+;; n for the next entry
+;; p for the previous entry
+;; P print
+;; q to save the list and exit the buffer
+;; r to raise the current entry's priority
+;; s to save the list
+;; S to save the list of top priorities
+;; t show top priority items for each category
+;;
+;; When you add a new entry, you are asked for the text and then
+;; for the category. I for example have categories for things
+;; that I want to do in the office (like mail my mum), that I
+;; want to do in town (like buy cornflakes) and things I want to
+;; do at home (move my suitcases). The categories can be
+;; selected with the cursor keys and if you type in the name of a
+;; category which didn't exist before, an empty category of the
+;; desired name will be added and filled with the new entry.
+;;
+;; Configuration
+;;
+;; Variable todo-prefix
+;;
+;; I would like to recommend that you use the prefix "*/*" (by
+;; leaving the variable 'todo-prefix' untouched) so that the
+;; diary displays each entry every day.
+;;
+;; To understand what I mean, please read the documentation that
+;; goes with the calendar since that will tell you how you can
+;; set up the fancy diary display and use the #include command to
+;; include your todo list file as part of your diary.
+;;
+;; If you have the diary package set up to usually display more
+;; than one day's entries at once, consider using
+;;
+;; "&%%(equal (calendar-current-date) date)"
+;;
+;; as the value of `todo-prefix'. Please note that this may slow
+;; down the processing of your diary file some.
+;;
+;; Carsten Dominik <dominik@strw.LeidenUniv.nl> suggested that
+;;
+;; "&%%(todo-cp)"
+;;
+;; might be nicer and to that effect a function has been declared
+;; further down in the code. You may wish to auto-load this.
+;;
+;; Carsten also writes that that *changing* the prefix after the
+;; todo list is already established is not as simple as changing
+;; the variable - the todo files have to be changed by hand.
+;;
+;; Variable todo-file-do
+;;
+;; This variable is fairly self-explanatory. You have to store
+;; your TODO list somewhere. This variable tells the package
+;; where to go and find this file.
+;;
+;; Variable todo-file-done
+;;
+;; Even when you're done, you may wish to retain the entries.
+;; Given that they're timestamped and you are offered to add a
+;; comment, this can make a useful diary of past events. It will
+;; even blend in with the EMACS diary package. So anyway, this
+;; variable holds the name of the file for the filed todo-items.
+;;
+;; Variable todo-file-top
+;;
+;; File storing the top priorities of your TODO list when
+;; todo-save-top-priorities is non-nil. Nice to include in your
+;; diary instead of the complete TODO list.
+;;
+;; Variable todo-mode-hook
+;;
+;; Just like other modes, too, this mode offers to call your
+;; functions before it goes about its business. This variable
+;; will be inspected for any functions you may wish to have
+;; called once the other TODO mode preparations have been
+;; completed.
+;;
+;; Variable todo-insert-threshold
+;;
+;; Another nifty feature is the insertion accuracy. If you have
+;; 8 items in your TODO list, then you may get asked 4 questions
+;; by the binary insertion algorithm. However, you may not
+;; really have a need for such accurate priorities amongst your
+;; TODO items. If you now think about the binary insertion
+;; halfing the size of the window each time, then the threshhold
+;; is the window size at which it will stop. If you set the
+;; threshhold to zero, the upper and lower bound will coincide at
+;; the end of the loop and you will insert your item just before
+;; that point. If you set the threshhold to, e.g. 8, it will stop
+;; as soon as the window size drops below that amount and will
+;; insert the item in the approximate centre of that window. I
+;; got the idea for this feature after reading a very helpful
+;; e-mail reply from Trey Jackson <trey@cs.berkeley.edu> who
+;; corrected some of my awful coding and pointed me towards some
+;; good reading. Thanks Trey!
+;;
+;; Things to do
+;;
+;; These originally were my ideas, but now also include all the
+;; suggestions that I included before forgetting them:
+;;
+;; o Fancy fonts for todo/top-priority buffer
+;; o Remove todo-prefix option in todo-top-priorities
+;; o Rename category
+;; o Move entry from one category to another one
+;; o Entries which both have the generic */* prefix and a
+;; "deadline" entry which are understood by diary, indicating
+;; an event (unless marked by &)
+;; o The optional COUNT variable of todo-forward-item should be
+;; applied to the other functions performing similar tasks
+;; o Modularization could be done for repeaded elements of
+;; the code, like the completing-read lines of code.
+;; o license / version function
+;; o export to diary file
+;; o todo-report-bug
+;; o GNATS support
+;; o elide multiline (as in bbdb, or, to a lesser degree, in
+;; outline mode)
+;; o rewrite complete package to store data as lisp objects
+;; and have display modes for display, for diary export,
+;; etc. (Richard Stallman pointed out this is a bad idea)
+;; o so base todo-mode.el on generic-mode.el instead
+;;
+;; History and Gossip
+;;
+;; Many thanks to all the ones who have contributed to the
+;; evolution of this package! I hope I have listed all of you
+;; somewhere in the documentation or at least in the RCS history!
+;;
+;; Enjoy this package and express your gratitude by sending nice
+;; things to my parents' address!
