(I'm the maintainer of the Debian package of scsh.)
As you may or may not know, Debian has recently changed the part of
its constitution that defines what can and cannot be in Debian on
freeness grounds. In short, it has been decided that everything, not
only programs, must be free or chucked out of Debian, where "free" is
judged along the exact same standards as with programs.
The things in "doc/" from the tarball don't seem to bear a license of
their own. Does this mean they are under the license in "COPYING" (the
3-clause BSD-ish license)?
This change of rules on freeness requirements will come into effect
only with the release of Debian following the next one, so it is not
tremendously urgent to resolve this, but I'd like to get rid of the
Best Regards and thank you for your help,
