/**
 * Interface defining a client able to execute commands against Redis.
 *
 * All the commands exposed by the client generally have the same signature as
 * described by the Redis documentation, but some of them offer an additional
 * and more friendly interface to ease programming which is described in the
 * following list of methods:
