Good idea.

I actually did not want to fiddle with the file names, as it is to
easy to forget some: this concerns in my case literate programming of
a simulation model in R, resul;ting in several files of different
extensions - it is to easy to forget one.

If I tangle, I get all the names of the tangled files, but I do not
know how I can feed them into the zip file.

I assume, it is caused by the :exports none - so no evaluation is done
on export. Try changing it to :exports result and then generate an
empty result, or a list of files included in the zip file.
