;;; Commentary:
;; This version of mediawiki.el represents a merging of
;; wikipedia-mode.el (maintained by Uwe Brauer <oub at mat.ucm.es>)
;; from http://www.emacswiki.org/emacs/wikipedia-mode.el for its
;; font-lock code, menu, draft mode, replying and convenience
;; functions to produce mediawiki.el 2.0.
;;; Installation
;; If you use ELPA (http://tromey.com/elpa), you can install via the
;; M-x package-list-packages interface. This is preferrable as you
;; will have access to updates automatically.
;; Otherwise, just make sure this file is in your load-path (usually
;; ~/.emacs.d is included) and put (require 'mediawiki.el) in your
;; ~/.emacs or ~/.emacs.d/init.el file.
;;; Howto:
;; M-x customize-group RET mediawiki RET
;; *dink* *dink*
;; M-x mediawiki-site RET Wikipedia RET
;;
;; Open a wiki file: M-x mediawiki-open
;; Save a wiki buffer: C-x C-s
;; Save a wiki buffer with a different name: C-x C-w
;;; TODO:
;; * Optionally use org-mode formatting for editing and translate
;; that to mw
;; * Move url-* methods to url-http
;; * Use the MW API to support searching, etc.
;; * Clean up and thoroughly test imported wikimedia.el code
;; * Improve language support. Currently there is a toggle for
;; English or German. This should probably just be replaced with
;; customizable words given MediaWiki's wide language support.
;;; History
;; From the News section of wikipedia.el comes this bit, kept here for
;; reference later.
;; (4) "Draft", "send" and "reply" (for discussion pages)
;; abilities `based' on ideas of John Wigleys remember.el: see
;; the functions wikipedia-draft-*
;; RATIONALE: This comes handy in 2 situations
;; 1. You are editing articles which various authors (this I
;; think is the usual case), you then want not to submit
;; your edit immediately but want to copy it somewhere and
;; to continue later. You can use the following functions
;; for doing that:
;; wikipedia-draft-buffer \C-c\C-b
;; wikipedia-draft-region \C-c\C-r
;; then the buffer/region will be appended to the
;; wikipedia-draft-data-file (default is
;; "~/Wiki/discussions/draft.wiki", which you can visit via
;; wikipedia-draft-view-draft) and it will be
;; surrounded by the ^L marks in order to set a page.
;; moreover on top on that a section header == will be
;; inserted, which consists of the Word Draft, a subject
;; you are asked for and a date stamp.
;;
;; Another possibility consists in using the function
;; wikipedia-draft, bound to \C-c \C-m then a new buffer
;; will opened already in wikipedia mode. You edit and then
;; either can send the content of the buffer to the
;; wikipedia-draft-data-file in the same manner as
;; described above using the function
;; wikipedia-draft-buffer (bound to \C-c\C-k)
;;
;; BACK: In order to copy/send the content of temporary
;; buffer or of a page in the wikipedia-draft-data-file
;; back in to your wikipedia file, use the function
;; wikipedia-send-draft-to-mozex bound to "\C-c\C-c". You
;; will be asked to which buffer to copy your text!
;;
;;
;; 2. You want to reply in a discussion page to a specific
;; contribution, you can use either the function
;;
;; \\[wikipedia-reply-at-point-simple] bound to [(meta shift r)]
;; which inserts a newline, a hline, and the signature of
;; the author. Or can use
;; \\[wikipedia-draft-reply] bound [(meta r)]
;; which does the same as wikipedia-reply-at-point-simple
;; but in a temporary draft buffer.
;;
;; BACK: In order to copy/send the content of that buffer
;; back in to your wikipedia file, use the function
;; \\[wikipedia-send-draft-to-mozex] bound to "\C-c\C-c". You
;; will be asked to which buffer to copy your text! If
;; you want a copy to be send to your draft file, use
;; the variable wikipedia-draft-send-archive
