I meant 'done and made publicly available.' Do you have a reference, please?

It seems beyond what I know. But it sounds as if its trivial nature still runs into problems?
I must say as a more involved project I imagine and hope for producing a multi-page pdf file that has a logo on each page of the very same page.
