								package client


								/*

								The client package provides a general purpose interface (Client) for connecting

								to a tendermint node, as well as higher-level functionality.


								The main implementation for production code is client.HTTP, which

								connects via http to the jsonrpc interface of the tendermint node.


								For connecting to a node running in the same process (eg. when

								compiling the abci app in the same process), you can use the client.Local

								implementation.


								For mocking out server responses during testing to see behavior for

								arbitrary return values, use the mock package.


								In addition to the Client interface, which should be used externally

								for maximum flexibility and testability, and two implementations,

								this package also provides helper functions that work on any Client

								implementation.
