[tw5] Exporting tiddler as header file format.

Dear all,
I would like to ask you about the following feature that I want to implement. I want to export my tiddler as header file(*.h) format which is not availabe now. How can I add a button that can implement this task sothat this file format will appear with the existing file formats like JSON file, STATIC HTML…? I am grateful for your help.
Regards,
Kidanu
