+
+;;; Commentary:
+
+;; This is yet another implementation to insert a randomly choosen
+;; signature into a mail.
+
+;; It is only tested with gnus.
+
+;; To make it work, put the following lines into your ~/.gnus:
+
+;; (require 'randomsig)
+;; (define-key message-mode-map (kbd "C-c s") 'randomsig-replace-sig)
+;; (define-key message-mode-map (kbd "C-c S") 'randomsig-select-sig)
+;; (require 'gnus-sum) ; probably required for `gnus-summary-save-map'
+;; (define-key gnus-summary-save-map "-" 'gnus/randomsig-summary-read-sig)
+;; (setq randomsig-dir "/some/directory")
+;; (setq randomsig-files '("some" "files"))
+;; ;; or (setq randomsig-files (randomsig-search-sigfiles))
+;; ;; or (setq randomsig-files 'randomsig-search-sigfiles)
+;; (setq message-signature 'randomsig-signature)
+
+;; This will also define the shortcut `C-c s' in message-mode to
+;; change the signature, `C-c S' in message-mode to interactively
+;; select the signature to replace the current signature, and `O -' in
+;; gnus-summary-mode to read the signature from the selected mail.
+
+;; `randomsig-files' must be a list of existing files, an existing
+;; file, or a function returning a list of existing files. If these
+;; don't have absolute paths, they are located in `randomsig-dir'.
+
+;; File format: Each file must contain at least one signature.
+;; Signatures are separated with `randomsig-delimiter-pattern'. If
+;; there is only one signature in the file, the delimiter can be
+;; omitted, so real .signature-files can be used.
+
+;; `randomsig-delimiter' is used when inserting new signatures with
+;; `randomsig-message-read-sig' into the signature file. So
+;; `randomsig-delimiter' should match `randomsig-delimiter-pattern'.
+
+;; `randomsig-static-string' is put in front of every random signature
+;; if non-`nil'.
+
+;; The *-read-sig functions read the signature of a message, or use
+;; the marked text, and write it to a signature-file, for which the
+;; name is asked. If the file does not exist, it will be generated.
+;; When called with any prefix, the signatures will be offered to edit
+;; before saving.
+
+;; if `randomsig-replace-sig' is called with any prefix, it will ask
+;; for a file to get the signature from.
+
+;; `randomsig-select-sig' will offer a list of signatures to select
+;; from in an extra buffer. n will jump to the next signature, p to
+;; the previous, RET will insert the selected signature, q will exit
+;; the selection buffer without replacing the current signature, R
+;; will reload the signature-files, and e will open a buffer for
+;; editing the signature at the point. When called with any prefix, it
+;; will ask for a file to get the signatures from
+
+;; `randomsig-search-sigfiles' will search for regular files in
+;; `randomsig-dir', which do not match `randomsig-search-unwanted'. A
+;; subdirectory of `randomsig-dir' can be given as optional argument.
+
+;; Completion will only work for files in `randomsig-files', though
+;; others files can be used, too.
+
+;;; Changelog:
+
+;; 2001/04/12   0.1
+;; * Initial release
+
+;; 2001/04/19   0.2
+;; * inserted `randomsig-delimiter' to add the capability to change
+;;   the delimiter between the signatures (thanks to Andreas Büsching
+;;   <crunchy@tzi.de>)
+
+;; 2001/04/25   0.3
+;; * new function `randomsig-search-sigfiles', to search all regular files
+;;   in directory `randomsig-dir'
+;; * normal signatures only worked, when using only one signature. Fixed.
+
+;; 2001/04/25   0.3.1
+;; * Fixed a bug in `randomsig-search-sigfiles'
+
+;; 2001/04/26   0.3.2
+;; * replaced `point-at-eol' with `line-end-position' (Don't know where
+;;   `point-at-eol' is defined)
+;; * require cl
+;; * require message in some functions
+
+;; 2001/07/09   0.3.3
+;; * don't (setq message-signature 'randomsig-signature) by default,
+;;   the user can do this in his .gnus
+;; * remove unnecessary optional arguments to `find-file-noselect' to
+;;   make it work with XEmacs
+;; (Thanks to Micha Wiedenmann <Micha.Wiedenmann@gmx.net> for both
+;; suggestions)

+;; * new command `randomsig-select-sig' to interactively select a signature
+;; * new mode `randomsig-select-mode' (for `randomsig-select-sig')
+;; * `randomsig-files' can also be function returning a list of
+;;   Signature files
+;; * `randomsig-replace-sig' does not remove old signature when interrupted
+
+;; 2001/07/22   0.4.1
+;; * (require 'message) only when needed
+
+;; 2001/08/13   0.5.0
+;; * doesn't require message anymore, so it should work without gnus
+
+;; 2001/08/20   0.5.1
+;; * add (random t) to initialize random seed (thanks to Evgeny
+;;   Roubinchtein <evgenyr@cs.washington.edu> for pointing this out
+;; * insert a newline if it is missing at the end of a signature file
+
+;; 2001/09/17   0.5.2

+;;   <rscholz@zonix.de>)
+
+;; 2001/10/01   0.5.3
+;; * Documentation updates
+
+;; 2002/01/20   0.5.99
+;; * It is now possible to edit signatures before saving, or to edit
+;;   single signatures from the selection buffer.
+;; * Mark many variables as user option
+;; * randomsig-files-to-list works recursive
+
+;; 2002/03/04   0.6.0
+;; * `randomsig-replace-signature-in-signature-files' should be safer now
+;; * `randomsig-files-to-list' did endless recursion when called
+;;   with nil. Fixed.
+;; * Some error-handling for non-existing `randomsig-dir'.
+
+;; 2002/09/21   0.7.0
+;; * most variables customizable
+;; * `randomsig-static-string' works for `randomsig-select-sig', too
+;;   (thanks to Mark Trettin <mtr-dev0@gmx.de> for pointing this out)
+;; * documentation updates
