Hi

I would like to have two different versions (not in the sense of version
control) of one program in one org file, and depending on the value if a
tag is set or not, tangle either the one or the other. The tangled file
has to have the same name.

So essentially:



** Test Code              :VERSIONTAG
Version 1:
#+begin_src R :tangle result.R
  version <- 1
  x <- 10
#+end_src

Version 2:
#+begin_src R :tangle result.R
  version <- 2
  x <- 13
#+end_src

If VERSIONTAG is Version1, result.R should contain the code as in the
first code block, and if it is Version2, the code from the second code
block.


Is this possible?

Cheers,

Rainer
