-CIDER is distributed with its own license (see below) that is not compatible
-to DFSG (https://embedded.eecs.berkeley.edu/pubs/downloads/cider/index.htm).
-CIDER shall be covered New BSD according to UCB officials, but this
-re-licensing is still under discussion
-(see https://lists.debian.org/debian-legal/2016/10/msg00022.html).
-Therefore CIDER may not be made available in all software distributions.
