;;
! ;; In addition to outline navigation and exposure, allout includes:
;;
! ;; - topic-oriented repositioning, cut, and paste
! ;; - integral outline exposure-layout
! ;; - incremental search with dynamic exposure and reconcealment of hidden
text
;; - automatic topic-number maintenance
! ;; - "Hot-spot" operation, for single-keystroke maneuvering and
! ;; exposure control. (See the `allout-mode' docstring.)
;;
! ;; and many other features.

;; The outline menubar additions provide quick reference to many of
! ;; the features, and see the docstring of the function `allout-init'
! ;; for instructions on priming your Emacs session for automatic
! ;; activation of `allout-mode'.

! ;; Some features:
;;
! ;; - classic outline-mode topic-oriented navigation and exposure adjustment
! ;; - topic-oriented editing including coherent topic and subtopic
! ;; creation, promotion, demotion, cut/paste across depths, etc
! ;; - incremental search with dynamic exposure and reconcealment of text
! ;; - customizable bullet format enbles programming-language specific
! ;; outlining, for ultimate code-folding editing. (allout code itself is
! ;; formatted as an outline - do ESC-x eval-current-buffer in allout.el
! ;; to try it out.)
! ;; - configurable per-file initial exposure settings
! ;; - symmetric-key and key-pair topic encryption, plus reliable key
! ;; verification and user-supplied hint maintenance. (see
! ;; allout-toggle-current-subtree-encryption docstring.)
;; - automatic topic-number maintenance
! ;; - "hot-spot" operation, for single-keystroke maneuvering and
! ;; exposure control (see the allout-mode docstring)
! ;; - easy rendering of exposed portions into numbered, latex, indented, etc
! ;; outline styles
;;
! ;; and more.

+ currently being edited. \(In that case, the currently edited topic
+ will be automatically decrypted before any user interaction, so they
+ can continue editing but the copy on the file system will be
+ encrypted.)
+ Auto-saves will use the \"All except current topic\" mode if this
+ one is selected, to avoid practical difficulties - see below.
+ - All except current topic: skip the topic currently being edited, even if
+ it's pending encryption. This may expose the current topic on the
+ file sytem, but avoids the nuisance of prompts for the encryption
+ key in the middle of editing for, eg, autosaves.
+ This mode is used for auto-saves for both this option and \"Yes\".
+ - No: leave it to the user to encrypt any unencrypted topics.
+
+ For practical reasons, auto-saves always use the 'except-current policy
+ when auto-encryption is enabled. \(Otherwise, spurious key prompts and
+ unavoidable timing collisions are too disruptive.) If security for a file

+ Outline mode supports easily togglable gpg encryption of topics, with

! "Encrypt clear text or decrypt encoded contents of a topic.
!
! Contents includes body and subtopics.
!
! Currently only GnuPG encryption is supported.
!
! \**NOTE WELL** that the encrypted text must be ascii-armored. For gnupg
! encryption, include the option ``armor'' in your ~/.gnupg/gpg.conf file.
!
! Both symmetric-key and key-pair encryption is implemented. Symmetric is
! the default, use a single \(x4) universal argument for keypair mode.
!
! Encrypted topic's bullet is set to a `~' to signal that the contents of the
! topic \(body and subtopics, but not heading) is pending encryption or
! encrypted. An `*' asterisk immediately after the bullet signals that the
! body is encrypted, its absence means it's meant to be encrypted but is not
! - it's \"disclosed\". When a file with disclosed topics is saved, the user
! prompted for an ok to \(symmetric-key) encrypt the disclosed topics. NOTE
! WELL that you must explicitly \(re)encrypt key-pair encrypted topics if you
! want them to continue to be in key-pair mode.
!
! Level-1 topics, with prefix consisting solely of an `*' asterisk, cannot be
! encrypted. If you want to encrypt the contents of a top-level topic, use
! \\[allout-shift-in] to increase its depth.
!
! Failed transformation does not change the an entry being encrypted -
! instead, the key is re-solicited and the transformation is retried.
! \\[keyboard-quit] to abort.
!
! Decryption does symmetric or key-pair key mode depending on how the text
! was encrypted. The encryption key is solicited if not currently available
! from the key cache from a recent prior encryption action.
!
! Optional FETCH-KEY universal argument is used for two purposes - to provoke
! key-pair instead of symmetric encryption, or to provoke clearing of the key
! cache so keys are freshly fetched.
!
! - Without any universal arguments, then the appropriate key for the is
! obtained from the cache, if available, else from the user.
!
! - If FETCH-KEY is the result of one universal argument - ie, equal to 4 -
! then key-pair encryption is used.
!
! - With repeated universal argument - equal to 16 - then the key cache is
! cleared before any encryption transformations, to force prompting of the
! user for the key.
!
! The solicited key is retained for reuse in a buffer-specific cache for some
! set period of time \(default, 60 seconds), after which the string is
! nulled. `mailcrypt' provides the key caching functionality. You can
! adjust the key cache timeout by ajdusting the setting of the elisp variable
! `mc-passwd-timeout'.
!
! If the file previously had no associated key, or had a different key than
! specified, the user is prompted to repeat the new one for corroboration. A
! random string encrypted by the new key is set on the buffer-specific
! variable `allout-key-verifier-string', for confirmation of the key when
! next obtained, before encrypting or decrypting anything with it. This
! helps avoid mistakenly shifting between keys.
!
! If allout customization var `allout-key-verifier-handling' is non-nil, an
! entry for `allout-key-verifier-string' and its value is added to an Emacs
! 'local variables' section at the end of the file, which is created if
! necessary. That setting is for retention of the key verifier across emacs
! sessions.
!
! Similarly, `allout-key-hint-string' stores a user-provided reminder about
! their key, and `allout-key-hint-handling' specifies when the hint is
! presented, or if key hints are disabled. If enabled \(see the
! `allout-key-hint-handling' docstring for details), the hint string is
! stored in the local-variables section of the file, and solicited whenever
! the key is changed."
