Org’s export engine makes it easy for writing new back-ends. The framework on which the engine was built makes it easy to derive new back-ends from existing ones.
The two main entry points to the export engine are:
org-export-define-backend and org-export-define-derived-backend.
To grok these functions, see ‘ox-latex.el’ for an example of defining
a new back-end from scratch, and ‘ox-beamer.el’ for an example of
deriving from an existing engine.
For creating a new back-end from scratch, first set its name as
a symbol in an alist consisting of elements and export functions. To
make the back-end visible to the export dispatcher, set :menu-entry
keyword. For export options specific to this back-end, set the
:options-alist.
For creating a new back-end from an existing one, set
:translate-alist to an alist of export functions. This alist
replaces the parent back-end functions.
