[Orgmode] copying headline structure without contents

[Rainer Stengele]

hi all,

is it possible to clone all visible or marked headlines without contents?

Example:


Having these lines:

* header1
  - contents
** header11
   - contents
* header2
  - contents
** header21
   - contents


I'd like to have


* header1
  - contents
** header11
   - contents
* header2
  - contents
** header21
   - contents
* header1
** header11
* header2
** header21


application:
having written a spec for a job I want to write another
one for a similar subject with headlines as before but changed contents


Thanks for any thought!

Rainer
