Re: [O] [ANN] Convert Org-mode file to Source-code file

[Eric Schulte]

How does this differ from ":tangle yes :comments org"?

e.g.,

#+Property: tangle yes
#+Property: comments org

* This is the top

#+begin_src sh :shebang #!/bin/bash
  echo "##this file will cat itself"
  echo ""
#+end_src

tangles to
