;;{{{ Change Log
;;{{{ Changes from 3.0:
;; * Generate a warning if some public keys are found while others
;;   are not during encryption.
;; * Rewrite calls like (message msg) to (message "%s" msg), in case
;;   msg includes a "%".
;; * Handle case in mc-pgp-decrypt-region when signature verifies, but
;;   key has not been certified.
;; * Put save-excursion around each top-level function.
;; * Handle case in mc-pgp-decrypt-region when signature fails to verify
;;   because you don't have the necessary public key.
;; * Locally bind mc-encrypt-for-me to nil before encrypting in
;;   mc-remail.
;; * Include "+encrypttoself=off" in PGP command line flags.
;; * Include "+verbose=1" in PGP command line flags (finally).
;; * Hacked mc-rmail-verify-signature to make sure rmailkwd is loaded
;;   before message is verified.
;; * (require 'gnus) when compiling.  Thanks to Peter Arius
;;    <arius@immd2.informatik.uni-erlangen.de>
;;}}}
;;{{{ Changes from 2.0:
;; * C-u to mc-encrypt-message now prompts for an ID to use
;;   for signing.  C-u C-u also prompts for scheme to use.
;; * Signing now uses the From line (pseudonym) to choose key.
;; * Support for multiple secret keys added.  Many internal interfaces
;;   changed.
;; * autoload remailer support for mc-remail.el and set default keybindings.
;; * mc-pgp-always-sign now has a 'never option.
;; * mc-pgp-encrypt-region returns t on success.
;; * Added mc-vm-snarf-keys, from Joe Reinhardt
;;   <jmr@everest.radiology.uiowa.edu>.
;; * Changed mc-snarf-keys to actually snarf all keys in the buffer instead
;;   of just the first one.
;; * In VM, not replacing a message puts the message into its own VM buffer
;;   so you can reply to it, forward it, etc. Thanks to Pat Lopresti
;;   <patl@lcs.mit.edu> for the suggestion.
;; * Abort edit mode in VM and RMAIL decrypt functions if no encrypted 
;;   message was found. 
;; * Added version string.
;; * Applied some new patches from stig adding autoloads and minor additions.
;; * Made check for window-system generic, and only for emacs versions > 19.
;; * Added option to mc-sign-message to disable clearsig when signing messages.
;;   From Stig <stig@hackvan.com>.
;; * Fixed extra comma bug when offering default recipients to encrypt for.
;;}}}
;;{{{ Changes from 1.6:
;; * Decrypting a signed message in RMAIL adds a verified tag to the message.
;; * mc-sign-message takes an optional argument specifying which key to use,
;;   for people who have multiple private keys.
;; * Added mc-{pre,post}-{de,en}cryption-hooks.
;; * Additions to docstrings of the major functions and `mailcrypt-*' aliases
;;   for the same.
;; * Added cleanup for possible temp files left over if a process was
;;   interrupted.
;; * Easier installation instructions.
;; * Lots of little bug fixes from all over. Too many to list
;;   individual credits, but I've tried to include all of them. Thanks
;;   to all who sent them in, especially to John T Kohl who fixed an
;;   especially trying problem.
;; * Another optional argument to mc-insert-public-key that allows the
;;   user to specify which public key to insert when called with a
;;   prefix argument.
;; * Tons of changes from Paul Furnanz <paul_furnanz@rainbow.mentorg.com>:
;; 1) Use the itimer package instead of the timer package if it exists.
;;    This makes the password deactivation code work for Lemacs as well
;;    as emacs 19.
;; 2) Fractured the code, so that there is a single function to use
;;    when calling the encryption program.  The new function is
;;    mc-process-region.  The function copies all data to a temporary
;;    buffer, and does the work there.  This way if you do an undo after
;;    an encryption or signing, your password is not visible on the
;;    screen. 
;; 3) All process output goes to the *MailCrypt* buffer.  No longer use
;;    a separate buffer for decryption, encryption, verification, ...
;;    This allows the user to always look at the *MailCrypt* buffer to
;;    see what pgp or ripem said.
;; 4) No longer call mc-temp-display.  Use display-buffer if there is a
;;    reason to show the buffer (like an error occured).
;; 5) Try to print more useful messages.
;; 6) If an error occurs on encryption, the message is left unchanged.
;;    No reason to undo.
;;}}}
;;{{{ Changes from 1.5:
;; * Changed mc-temp-display to just dump into a temp buffer, without
;;   any fancy display stuff. Pick up show-temp.el if you liked the
;;   display stuff (or uncomment the old mc-temp-buffer and remove the
;;   new version).
;; * Provided a generic read mode function to call in hooks, like the
;;   generic write mode function that was already there.
;; * Fixed bug in regexp that prevented compilation under recent
;;   versions of FSF emacs.
;; * Narrow to headers when extracting default recipients for encryption
;;   to avoid pulling in recipients of included messages.
;; * Use `fillarray' to overwrite passwords with nulls before deactivation
;;   for increased security.
;; * Load mail-extr.el to get mail-extract-address-components defined.
;; Thanks to Kevin Rodgers <kevin@traffic.den.mmc.com> for the following
;; improvements.
;; * Quoted an unquoted lambda expression that prevented optimized 
;;   compilation under emacs 18.
;; * Used `nconc' instead of `append' in various places to save on 
;;   garbage collection.
;; * Modified mc-split to run more efficiently.
;;}}}
;;{{{ Changes from 1.4:
;; * Call mail-extract-address-components on the recipients if we guessed
;;   them from the header fields.
;; * If you don't replace a message with its decrypted version, it will now
;;   pop you into a view buffer with the contents of the message.
;; * Added support for mh-e, contributed by Fritz Knabe <Fritz.Knabe@ecrc.de>
;; * Fixed bug in snarfing keys from menubar under GNUS.
;; * Fixed RIPEM verification problem, thanks to Sergey Gleizer
;;   <sgleizer@cs.nmsu.edu>.
;;}}}
;;{{{ Changes from 1.3:
;; * Temp display function does not barf on F-keys or mouse events.
;;     Thanks to Jonathan Stigelman <stig@key.amdahl.com>
;; * Lucid emacs menu support provided by William Perry <wmperry@indiana.edu>
;; * Cited signed messages would interfere with signature 
;;	verification; fixed.
;;}}}
;;{{{ Changes from 1.2:
;; * Added menu bar support for emacs 19.
;; * Added GNUS support thanks to Samuel Druker <samuel@telmar.com>.
;;}}}
;;{{{ Changes from 1.1:
;; * Added recipients field to mc-encrypt-message.
;;}}}
;;{{{ Changes from 1.0:
;; * Fixed batchmode bug in decryption, where unsigned messages would return
;;   with exit code of 1.
;;}}}
;;{{{ Changes from 0.3b:
;; * Only set PGPPASSFD when needed, so PGP won't break when used
;;   in shell mode.
;; * Use call-process-region instead of shell-command-on-region in order
;;   to detect exit codes.
;; * Changed mc-temp-display to not use the kill ring.
;; * Bug fixes.
;;}}}
;;{{{ Changes from 0.2b:
;; * Prompts for replacement in mc-rmail-decrypt-message.
;; * Bug fixes.
;;}}}
;;{{{ Changes from 0.1b:
;; * Several bug fixes.
;; Contributed by Jason Merrill <jason@cygnus.com>:
;; * VM mailreader support
;; * Support for addresses with spaces and <>'s in them
;; * Support for using an explicit path for the pgp executable
;; * Key management functions
;; * The ability to avoid some of the prompts when encrypting
;; * Assumes mc-default-scheme unless prefixed
