Currently, the nexus files are in the C core repo: https://github.com/igraph/igraph/tree/master/nexus As I understand, this is independent functionality. Should we split it off into a separate repo?
Though nexus is offline now, there is value in preserving it in case someone would want to revive it in the future. But the C core repo doesn’t seem like the right place for it unless I missed some interdependency between them.
