Dear Nicolas and Chuck,

thanks for pointing me in the right direction. I never thought that 
macros were actually just an export feature, and that noweb replacements 
could be used as macros!

I am experiencing a little quirk though. Since I often edit this org 
file under Windows, the tangled files have Windows new lines, and 
(cygwin or any) bash doesn't like it. So I added a 
org-babel-post-tangle-hook that set-buffer-file-coding-system to unix. 
But the scripts that I tangle with a noweb ref end up with a weird ^M 
after each end of line. It seems this happens after the post-tangle 
hook. How could I take care of those ^M?

Thanks a lot,

Giacomo
