Hi Giorgio,

This is currently not possible as we're not currently expanding
#+include links during tangling.  I agree this would be useful behavior.

This seems to be related to a recent theme on the mailing list of
unifying tangling with the rest of the Org-mode export functionality.
Once/if tangling were treated as an export target, then things like the
expansion of #+include lines would come for free.

Thanks for bringing this up, this will be an important point to keep in
mind while figuring out the future of tangling.

Best -- Eric
