\class QSsh::SshRemoteProcess
\brief The SshRemoteProcess 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.
If the process needs a pseudo terminal, you can request one
via requestTerminal() before calling start().
