+
+;;; Commentary:
+
+;; Requires at least version 4.27 of org.el
+
+;; This program allow configurable publishing of related sets of
+;; Org-mode files as a complete website.
+;;
+;; org-publish.el can do the following:
+;;
+;; + Publish all one's org-files to HTML or LaTeX
+;; + Upload HTML, images, attachments and other files to a web server
+;; + Exclude selected private pages from publishing
+;; + Publish a clickable index of pages
+;; + Manage local timestamps for publishing only changed files
+;; + Accept plugin functions to extend range of publishable content
+;;
+;; Special thanks to the org-mode maintainer Carsten Dominik for his
+;; ideas, enthusiasm, and cooperation.
+
+;;; Installation:
+
+;; Put org-publish.el in your load path, byte-compile it, and then add
+;; the following lines to your emacs initialization file:
+
+;; (autoload 'org-publish "org-publish" nil t)
+;; (autoload 'org-publish "org-publish-all" nil t)
+;; (autoload 'org-publish "org-publish-current-file" nil t)
+;; (autoload 'org-publish "org-publish-current-project" nil t)
+
+;; NOTE: When org-publish.el is included with org.el, those forms are
+;; already in the file org-install.el, and hence don't need to be put
+;; in your emacs initialization file in this case.
+
+;;; Usage:
+;;
+;; The program's main configuration variable is
+;; `org-publish-project-alist'. See below for example configurations
+;; with commentary.
+
+;; The main interactive functions are:
+;;
+;; M-x org-publish
+;; M-x org-publish-all
+;; M-x org-publish-current-file
+;; M-x org-publish-current-project
+
+;;;; Simple example configuration:
+
+;; (setq org-publish-project-alist
+;;       (list
+;;        '("org" . (:base-directory "~/org/"
+;; 		     :base-extension "org"
+;; 		     :publishing-directory "~/public_html"
+;;                   :with-section-numbers nil
+;; 		     :table-of-contents nil
+;;                   :recursive t
+;; 		     :style "<link rel=stylesheet href=\"../other/mystyle.css\" type=\"text/css\">")))
+
+;;;; More complex example configuration:
+
+;; Imagine your *.org files are kept in ~/org, your images in
+;; ~/images, and stylesheets in ~/other. Now imagine you want to
+;; publish the files through an ssh connection to a remote host, via
+;; Tramp-mode. To maintain relative links from *.org files to /images
+;; and /other, we should replicate the same directory structure in
+;; your web server account's designated html root (in this case,
+;; assumed to be ~/html)
+
+;; Once you've done created the proper directories, you can adapt the
+;; following example configuration to your specific paths, run M-x
+;; org-publish-all, and it should publish the files to the correct
+;; directories on the web server, transforming the *.org files into
+;; HTML, and leaving other files alone.
+
+;; (setq org-publish-project-alist
+;;       (list
+;;        '("orgfiles" :base-directory "~/org/"
+;; 		       :base-extension "org"
+;; 		       :publishing-directory "/ssh:user@host:~/html/notebook/"
+;; 		       :publishing-function org-publish-org-to-html
+;; 		       :exclude "PrivatePage.org"   ;; regexp
+;; 		       :headline-levels 3
+;;                     :with-section-numbers nil
+;; 		       :table-of-contents nil
+;; 		       :style "<link rel=stylesheet href=\"../other/mystyle.css\" type=\"text/css\">"
+;; 		       :auto-preamble t
+;; 		       :auto-postamble nil)
+;;         ("images" :base-directory "~/images/"
+;; 	             :base-extension "jpg\\|gif\\|png"
+;; 		     :publishing-directory "/ssh:user@host:~/html/images/"
+;; 		     :publishing-function org-publish-attachment)
+;;         ("other"  :base-directory "~/other/"
+;; 	   	     :base-extension "css"
+;; 		     :publishing-directory "/ssh:user@host:~/html/other/"
+;; 		     :publishing-function org-publish-attachment)
+;;         ("website" :components ("orgfiles" "images" "other"))))
+
+;; For more information, see the documentation for the variable
+;; `org-publish-project-alist'.
+
+;; Of course, you don't have to publish to remote directories from
+;; within emacs. You can always just publish to local folders, and
+;; then use the synchronization/upload tool of your choice.
+
+;;; List of user-visible changes since version 1.27
+
+;; 1.78: Allow list-valued :publishing-function
+;; 1.77: Added :preparation-function, this allows you to use GNU Make etc.
+;; 1.65: Remove old "composite projects". They're redundant.
+;; 1.64: Allow meta-projects with :components
+;; 1.57: Timestamps flag is now called "org-publish-use-timestamps-flag"
+;; 1.52: Properly set default for :index-filename
+;; 1.48: Composite projects allowed.
+;;       :include keyword allowed.
+;; 1.43: Index no longer includes itself in the index.
+;; 1.42: Fix "function definition is void" error
+;;       when :publishing-function not set in org-publish-current-file.
+;; 1.41: Fixed bug where index isn't published on first try.
+;; 1.37: Added interactive function "org-publish". Prompts for particular
+;;       project name to publish.
+;; 1.34: Added force-publish option to all interactive functions.
+;; 1.32: Fixed "index.org has changed on disk" error during index publishing.
+;; 1.30: Fixed startup error caused by (require 'em-unix)

+
+(defcustom org-publish-project-alist nil
+  "Association list to control publishing behavior.
+Each element of the alist is a publishing 'project.'  The CAR of
+each element is a string, uniquely identifying the project. The
+CDR of each element is in one of the following forms:
+
+  (:property value :property value ... )
+
+OR,
+
+  (:components (\"project-1\" \"project-2\" ...))
+
+When the CDR of an element of org-publish-project-alist is in
+this second form, the elements of the list after :components are
+taken to be components of the project, which group together files
+requiring different publishing options. When you publish such a
+project with M-x org-publish, the components all publish.
+
+When a property is given a value in org-publish-project-alist, its
+setting overrides the value of the corresponding user variable
+ (if any) during publishing. However, options set within a file
+override everything.
+
+Most properties are optional, but some should always be set:
+
+  :base-directory        Directory containing publishing source files
+  :base-extension        Extension (without the dot!) of source files.
+                         This can be a regular expression.
+  :publishing-directory  Directory (possibly remote) where output
+                         files will be published
+
+The :exclude property may be used to prevent certain files from
+being published. Its value may be a string or regexp matching
+file names you don't want to be published.
+
+The :include property may be used to include extra files. Its
+value may be a list of filenames to include. The filenames are
+considered relative to the publishing directory.
+
+When both :include and :exclude properties are given values, the
+exclusion step happens first.
+
+One special property controls which back-end function to use for
+publishing files in the project. This can be used to extend the
+set of file types publishable by org-publish, as well as the set
+of output formats.
+
+  :publishing-function     Function to publish file. The default is
+                           org-publish-org-to-html, but other
+                           values are possible. May also be a
+                           list of functions, in which case
+                           each function in the list is invoked
+                           in turn.
+
+Another property allows you to insert code that prepares a
+project for publishing. For example, you could call GNU Make on a
+certain makefile, to ensure published files are built up to date.
+
+  :preparation-function   Function to be called before publishing
+                          this project.
+
+Some properties control details of the Org publishing process,
+and are equivalent to the corresponding user variables listed in
+the right column. See the documentation for those variables to
+learn more about their use and default values.

+The following properties may be used to control publishing of an
+index of files or summary page for a given project.
+
+  :auto-index            Whether to publish an index during
+                         org-publish-current-project or org-publish-all.

+  :index-title           Title of index page. Defaults to name of file.
+  :index-function        Plugin function to use for generation of index.
+                         Defaults to 'org-publish-org-index', which
+                         generates a plain list of links to all files
