-Ethereum Go is split up in several sub packages Please refer to each
-individual package for more information.
- 1. [eth](https://github.com/ethereum/go-ethereum)
- 2. [ethchain](https://github.com/ethereum/go-ethereum/tree/master/ethchain)
- 3. [ethwire](https://github.com/ethereum/go-ethereum/tree/master/ethwire)

- 9. [ethreact](https://github.com/ethereum/go-ethereum/tree/master/ethreact)
- 10. [ethlog](https://github.com/ethereum/go-ethereum/tree/master/ethlog)
-
-The [eth](https://github.com/ethereum/go-ethereum) is the top-level package
-of the Ethereum protocol. It functions as the Ethereum bootstrapping and
-peer communication layer. The [ethchain](https://github.com/ethereum/go-ethereum/tree/master/ethchain)
-contains the Ethereum blockchain, block manager, transaction and
-transaction handlers. The [ethwire](https://github.com/ethereum/go-ethereum/tree/master/ethwire) contains
-the Ethereum [wire protocol](http://wiki.ethereum.org/index.php/Wire_Protocol) which can be used
-to hook in to the Ethereum network. [ethutil](https://github.com/ethereum/go-ethereum/tree/master/ethutil) contains
-utility functions which are not Ethereum specific. The utility package
-contains the [patricia trie](http://wiki.ethereum.org/index.php/Patricia_Tree),
-[RLP Encoding](http://wiki.ethereum.org/index.php/RLP) and hex encoding
-helpers. The [ethdb](https://github.com/ethereum/go-ethereum/tree/master/ethdb) package
-contains the LevelDB interface and memory DB interface.
+Go Ethereum comes with several binaries found in
+[cmd](https://github.com/ethereum/go-ethereum/tree/master/cmd):
+
+* `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`"`.
+* `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
+ 10000 -price 0 -dump`. See `-h` for a detailed description.
