as far as TeX is concerned I tried to put up references to what could be
called a license and copyright notices in
and Walter is wrong, it concerns file names and therefore has thesame problems
as LaTeX with DSFG 4 (or even more so in fact).

it must copyright and licenses, simply because
there are individual files with different licenses in there.
listing them, would be a nice try but hopeless as you would need to keep track
of i would guess more than 1000 individual works that end up in tetex texmf
trees. That would not be automatable and as a manual process it would be
always wrong. One could and most likely should however mention te licenses of
the main parts and perhaps list which licenses you might find.

think the current text in the TeX files is indeed very bad and unclear,
however there are clearer statements elsewhere (especially in the copyright
pages of the printed form of these files). --- again see the message
