[O] org-babel tangling + ascii export

[Ilya Shlyakhter]

Is it possible to combine org-babel tangling with ASCII export, so that
the tangled file would have ALL of the Org-file's content
as comments (preserving indentation etc as the ASCII export does),
with the code blocks inserted as non-comments?

Basically I want to write the program in literate-programming form in 
Org mode, but be able to export it into an executable form that's
independent of Org but still has all the information (not just the
text immediately before each code block).

Thanks for help,
