Bug#705152: Non-free code in xgraph? [copyright.h and derivative.c for starters.]

Package: xgraph
Severity: serious
Version: 12.1-15

Ulrich Mueller reported this to debian-legal@lists.debian.org. FWICT,
at least the contents of the source package are not distributable by
Debian in main. It's possible that the binary packages do not contain
any work which is copyrighted by Paul Walker, but the source packages
at least need to be altered to remove this non-free, non-distributable
code. [If I and Ulrich Mueller has misinterpreted what is going on
here, please let us know, and if at all possible, update
debian/copyright to explain in some future upload so we and others
don't revisit this erroneously in the future.]

Heh. That's not going to work. If that's actually the case, this code
has to be removed from the orig.tar.gz that Debian distributes.

I doubt that it is, or at least, the copyright and changes aren't
documented well enough for Debian to be able to properly distribute

Tell me something interesting about yourself.
Lie if you have to.
