The term might have been _coined_ by Richard Stallman, but is quite
used throughout the Free Software communities. Any license which (as
the GPL does) requires all further distributions of derivatives of the
original work under the same terms (particularly for software,
including full sources and the right to modify them) are termed
copyleft in general; non-code licenses such as the Creative Commons
(share-alike variants) are also copyleft licenses.

Right. I would add to your initial explanation that, having a
/usr/share/doc/PKGNAME/copyright, having any other files installed as
part of a binary package with licensing details can be considered a
bug, and only /usr/share/doc/PKGNAME/copyright should be considered
authoritative in a Debian system.
