Bug#645053: RM: qcad/stable,unstable,oldstable -- ROM; non-distributable files
Removal of qcad source and all binaries (qcad, qcad-doc, qcad-data) from
unstable, stable, and old-stable
1) qcad is produced by RibbonSoft and has been in Debian since 1999
2) upstream stopped maintaining the software, and Debian has been using qcad-
free  as upstream since 2009
3) recently a new project, librecad , has ported qcad to qt4 and is packaged
in debian as librecad
4) this week, RibbonSoft asked LibreCAD to stop distributing fonts, patterns,
example libraries, and documentation as they are not-free.
5) The project is advertised as GPLv2 and includes the text of the license with
the code. The header files of all source code has the GPL header, but there is
no explicit granting of GPL in the fonts, patterns, libraries, or
documentation. In face, the documentation says "All Rights Reserved"
6) Since qcad depends on qt3 (which will be removed by wheezy anyways), and
Debian is distributing non-distributable code in both binary and source
packages, it should be removed. After removal, a future upload of qcad can be
made as a transitional package recommending librecad, as per discussions on
debian-science mailing list.
