;;; Commentary:
|
|
;;
|
|
;; This library implements a DocBook exporter for org-mode. The basic
|
|
;; idea and design is very similar to what `org-export-as-html' has.
|
|
;; Code prototype was also started with `org-export-as-html'.
|
|
;;
|
|
;; Put this file into your load-path and the following line into your
|
|
;; ~/.emacs:
|
|
;;
|
|
;; (require 'org-docbook)
|
|
;;
|
|
;; The interactive functions are similar to those of the HTML and LaTeX
|
|
;; exporters:
|
|
;;
|
|
;; M-x `org-export-as-docbook'
|
|
;; M-x `org-export-as-docbook-pdf'
|
|
;; M-x `org-export-as-docbook-pdf-and-open'
|
|
;; M-x `org-export-as-docbook-batch'
|
|
;; M-x `org-export-as-docbook-to-buffer'
|
|
;; M-x `org-export-region-as-docbook'
|
|
;; M-x `org-replace-region-by-docbook'
|
|
;;
|
|
;; Note that, in order to generate PDF files using the DocBook XML files
|
|
;; created by DocBook exporter, the following two variables have to be
|
|
;; set based on what DocBook tools you use for XSLT processor and XSL-FO
|
|
;; processor:
|
|
;;
|
|
;; org-export-docbook-xslt-proc-command
|
|
;; org-export-docbook-xsl-fo-proc-command
|
|
;;
|
|
;; Check the document of these two variables to see examples of how they
|
|
;; can be set.
|
|
;;
|
|
;; If the Org file to be exported contains special characters written in
|
|
;; TeX-like syntax, like \alpha and \beta, you need to include the right
|
|
;; entity file(s) in the DOCTYPE declaration for the DocBook XML file.
|
|
;; This is required to make the DocBook XML file valid. The DOCTYPE
|
|
;; declaration string can be set using the following variable:
|
|
;;
|
|
;; org-export-docbook-doctype
|
|
;;

This command is used to process a DocBook XML file to generate

The value of this variable should be a format control string that

includes three arguments: `%i', `%o', and `%s'. During exporting

\"java org.apache.xalan.xslt.Process -out %o -in %i -xsl %s\"

For xsltproc, the following string should work:
