[Debian-med-packaging] Bug#979091: Legally problematic GPL-3+ readline dependency

[Bastian Germann]

Package: ctsim
Severity: important

This package depends on libreadline8 which is GPL-3+ licensed. According 
to debian/copyright parts of your package are GPL-2-only licensed. If 
that is also (transitively) the case for the binaries that link with 
libreadline.so.8 it might be legally problematic (see 
https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility).

There is an easy solution to the problem: Replacing the build dependency 
libreadline-dev with libeditreadline-dev links with the BSD-licensed 
libedit library which is a readline replacement.
