org: Adding export back-ends

 
 A.4 Adding export back-ends
 ===========================
 
 Org 8.0 comes with a completely rewritten export engine which makes it
 easy to write new export back-ends, either from scratch, or from
 deriving them from existing ones.
 
    Your two entry points are respectively ‘org-export-define-backend’
 and ‘org-export-define-derived-backend’.  To grok these functions, you
 should first have a look at ‘ox-latex.el’ (for how to define a new
 back-end from scratch) and ‘ox-beamer.el’ (for how to derive a new
 back-end from an existing one.
 
    When creating a new back-end from scratch, the basic idea is to set
 the name of the back-end (as a symbol) and an an alist of elements and
 export functions.  On top of this, you will need to set additional
 keywords like ‘:menu-entry’ (to display the back-end in the export
 dispatcher), ‘:export-block’ (to specify what blocks should not be
 exported by this back-end), and ‘:options-alist’ (to let the user set
 export options that are specific to this back-end.)
 
    Deriving a new back-end is similar, except that you need to set
 ‘:translate-alist’ to an alist of export functions that should be used
 instead of the parent back-end functions.
