AFAIK, you do have to write it yourself, but org-mode provides decent tools
for doing it. Here is an example. Run the src-block and a table of contents
will appear near the top. Change the content and rerun the src-block and
the t-o-c will change accordingly.
It doesn't deal with rules for omitting headlines like
COMMENT, :noexport:, etc, but if you are simply copying the .org file,
maybe it is good enough.
