 Usage: `consul reload`
 
-The command-line flags are all optional. The list of available flags are:
-
-* `-rpc-addr` - Address to the RPC server of the agent you want to contact
-  to send this command. If this isn't specified, the command checks the
-  CONSUL_RPC_ADDR env variable. If this isn't set, the default RPC 
-  address will be set to "127.0.0.1:8400".
