Hi,

Could anyone please give a working example of this? I tried tangling
the following:

   * A tangle example

   #+source: body
   #+begin_src ruby :comments yes :noweb yes
     puts "hello"
   #+end_src

   #+source: method
   #+begin_src ruby :comments yes :noweb yes
     def hello
       <<body>>
     end
   #+end_src

   #+source: main
   #+begin_src ruby :comments yes :tangle detangle.rb :noweb yes
     <<method>>
     hello
   #+end_src

and got the output:

   # [[][main]]

   def hello
     puts "hello"
   end
   hello

   # main ends here

which doesn't look right to me.

Regards,
Sean
