Help tangling

[Andreas Hilboll <lists@hilboll.de>]

Hi,

I want to write a "SConstruct" file (for SCons, a Python make
alternative) in orgmode, using literate programming.  So I have a file
"SConstruct.org", where I include the code blocks with "#+begin_src ...
#+end_src".  My question:

   How can I specify that *all* code blocks shall be tangled into one
single file called "SConstruct"?

I know I could do this by writing

   #+begin_src python :tangle SConstruct
   [...]
   #+end_src

instead of

   #+begin_src
   [...]
   #+end_src

but is there some way to define the "python" and the ":tangle
SConstruct" 'globally' for the whole file?

Thanks for helping me orgmode-newbie!
