;;; Commentary:
;; 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 PDF
;; + Upload HTML, images, attachments and other files to a web server
;; + Exclude selected private pages from publishing
;; + Publish a clickable sitemap of pages
;; + Manage local timestamps for publishing only changed files
;; + Accept plugin functions to extend range of publishable content
;;
;; Documentation for publishing is in the manual.

(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:
1. A well-formed property list with an even number of elements, alternating
keys and values, specifying parameters for the publishing process.
(:property value :property value ... )
2. A meta-project definition, specifying of a list of sub-projects:
(: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 \\[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. If not given,
\"org\" will be used as default extension.
: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 base 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. This may also be a list
of functions.
:completion-function Function to be called after publishing
this project. This may also be a list
of functions.
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 a
sitemap of files or summary page for a given project.
:auto-sitemap Whether to publish a sitemap during
`org-publish-current-project' or `org-publish-all'.
:sitemap-filename Filename for output of sitemap. Defaults
to 'sitemap.org' (which becomes 'sitemap.html').
:sitemap-title Title of sitemap page. Defaults to name of file.
:sitemap-function Plugin function to use for generation of sitemap.
Defaults to `org-publish-org-sitemap', which
generates a plain list of links to all files
in the project.
:sitemap-style Can be `list' (sitemap is just an itemized list
of the titles of the files involved) or
`tree' (the directory structure of the source
files is reflected in the sitemap). Defaults to
`tree'.
:sitemap-sans-extension Remove extension from sitemap's
filenames. Useful to have cool
URIs (see
http://www.w3.org/Provider/Style/URI).
Defaults to nil.
If you create a sitemap file, adjust the sorting like this:
:sitemap-sort-folders Where folders should appear in the sitemap.
Set this to `first' (default) or `last' to
display folders first or last, respectively.
Any other value will mix files and folders.
:sitemap-sort-files The site map is normally sorted alphabetically.
You can change this behaviour setting this to
`chronologically', `anti-chronologically' or nil.
:sitemap-ignore-case Should sorting be case-sensitive? Default nil.
The following properties control the creation of a concept index.
:makeindex Create a concept index.
Other properties affecting publication.
:body-only Set this to 't' to publish only the body of the
documents, excluding everything outside and
including the <body> tags in HTML, or
\begin{document}..\end{document} in LaTeX."
