I downloaded the 0.5.0 release from here:https://github.com/BitShares/bitshares/releases
unpacked it and there is only 1 file: "bitshares_client"
when I run it I get the following which I don't understand:
Loading blockchain from: /home/user1/.BitShares/chain
Loading config from file: /home/user1/.BitShares/config.json
Not starting RPC server, use --server to enable the RPC interface
