@ -46,7 +46,7 @@ Go Ethereum comes with several binaries found in
* `mist` Official Ethereum Browser
* `ethereum` Ethereum CLI
* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/testes) suit:
`ethtest "`cat myfile.json`"`.
`cat file | ethtest`.
* `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
