I'm in the process of vetting the documentation files that we're
distributing with the tetex-* packages.  Most are DFSG-free --
under the LPPL (okay with source in tetex-src), GPL, their own
DFSG-compliant license, or in the public domain.

There are about 30 documents (and the stuff they document) whose
licensing status is less clear, and those are the ones that I have
some questions on.  I have included some example
copyright/distribution statements based on those in this
unknown'' category, and I would appreciate a quick take from
debian-legal habitues on whether they are DFSG-free, and, in
particular, whether we can continue to distribute files with
copyright/distribution statements similar to the examples.

I will be attempting to contact the authors of the files that
aren't DFSG-free to encourage them to clarify the licensing of
their works (probably we'll get LPPL for most, although I'm happy
to mention alternatives).

In the meantime, should we drop the possibly problematic files
from our packages, or can we continue distributing them on the
basis that we have been distributing them without problems thus
far, and that CTAN continues to include them in their free''
section?  (Files that are egregiously non-DFSG-free will, of
course, be dropped.)
