Hi,

I did not know this either.  Thanks for the hint!

Shouldn't this be mentioned in the manual (14.4)?

I have two questions/issues about this:
(1) Can I get noweb-references to be expanded by this?  Or how would I
    tangle one block with noweb references expanded?
(2) I am asked for a filename.  But the header argument :tangle somefile
    is overruling my input, which is un-expected.

Regards,
Andreas
