Betreff: Re: [NTG-context] Parallel texts: verse with blanks between stanzas
via tabulate

Thanks, Wolfgang. That gives me a blank between the verses. However the
blank is rather huge and I don't see how I could make it smaller? Is it possible
to do this?
morning exercise attached (you can run the file)

Another, more general question on this: why is the function poetry.sidebyside
defined twice? If I understand correctly, depending on the input one or the
other will be used, but I don't see where that happens...
the first can be commented as it is the first simple variant
