+ * This class implements an SSH channel for running a remote process.
+ * Objects are created via SshConnection::createRemoteProcess.
+ * The process is started via the start() member function.
+ * A closeChannel() function is provided, but rarely useful, because
+ * a) when the process ends, the channel is closed automatically, and
+ * b) closing a channel will not necessarily kill the remote process.
+ * Therefore, the only sensible use case for calling closeChannel() is to
+ * get rid of an SshRemoteProces object before the process is actually started.
+ * Note that the process does not have a terminal, so you can't use it
+ * for applications that require one.
