[O] dotfile managment with #+BEGIN_SRC conf code blocks?

[Xebar Saram]

hi all

im looking at this link https://expoundite.net/guides/dotfile-management                       

this sound very nice. yet it says there to put your conf in org blocks with :  #+BEGIN_SRC conf       

yet i cant see this in the org-babel-load-languages or in any contrib files.                                                

how does one enable the conf code blocks, any clue?                                              

best
