In article by Michael Davidson:
I believe that it is sufficient to provide a single
copy of the license
/ copyright text from the letter along with any file or files that
either come directly from or are derived from
any of the listed operating systems.
I believe that's all we need to do. I'm only going to have 1 copy
of the license agreement in the Unix Archive, with the odd pointer
to it in some of the READMEs.
