  The content of the message is `'{"from":"currency","to":"inita","quantity":50}'`. In this case we are asking the currency contract to transfer funds from itself to someone else. This requires the permission of the currency contract.
  ```bash
  -./eosioc push message currency transfer '{"from":"currency","to":"inita","amount":50}' --scope currency,inita --permission currency@active
  +./eosioc push actions currency transfer '{"from":"currency","to":"inita","amount":50}' --scope currency,inita --permission currency@active
  ```
  Below is a generalization that shows the `currency` account is only referenced once, to specify which contract to deliver the `transfer` message to.
  ```bash
  -./eosioc push message currency transfer '{"from":"${usera}","to":"${userb}","amount":50}' --scope ${usera},${userb} --permission ${usera}@active
  +./eosioc push actions currency transfer '{"from":"${usera}","to":"${userb}","amount":50}' --scope ${usera},${userb} --permission ${usera}@active
  ```
  We specify the `--scope ...` argument to give the currency contract read/write permission to those users so it can modify their balances. In a future release scope will be determined automatically.
