Singularity [1] filed a deletion request for freeorion-bin [2]:
This package was meant to avoid long compiling times. However, it
turned later out that one needs to compile boost form AUR instead, and
now it's orphaned.
The bin was from the Debian software archive.
The freeorion-data package belongs together to this one and is not
used elsewhere, so both should be removed.
