syncthing-relaysrv 0.14.49+ds1-3 (s390x binary) in ubuntu cosmic

 Syncthing is an application that lets you synchronize your files across
 multiple devices. This means the creation, modification or deletion of files
 on one machine will automatically be replicated to your other devices.
 Syncthing does not upload your data to the cloud but exchanges your data
 across your machines as soon as they are online at the same time.
 .
 Syncthing relies on a network of community-contributed relay servers. Anyone
 can run a relay server, and it will automatically join the relay pool and be
 available to Syncthing users.
 .
 This package contains the relay server binary: strelaysrv.
