Ah...

Yes, sure.

Yes.

Checking more closely, it seems we have it. The detail is in
git@...hub.com:linux-speakup/speakup.git in ./doc/spkguide.txt, but that
seems relatively simple:

- The initial import of the file (bddef0d280cd) wears only the Gene
  Collins copyright notice.
- I made some changes and added my copyright notice.
- Christopher Brannon (now in Cc) made various changes and added the
  "the Speakup Team" copyright notice.
- William Hubbs (now in Cc) made some changes.
- Steve Holmes (now in Cc) added one sentence.

So we'd need Gene's, Christopher's, William's, and Steve's ack on adding
the GPL alternative to the GFDL-1.2 licence.
