Description:

def settrace(
    host=None,
    stdoutToServer=False,
    stderrToServer=False,
    port=5678,
    suspend=True,
    trace_only_current_thread=False,
    overwrite_prev_trace=False,
    patch_multiprocessing=False,
    stop_at_frame=None,
    ):
    '''Sets the tracing function with the pydev debug function and initializes needed facilities.

    @param host: the user may specify another host, if the debug server is not in the same machine (default is the local
        host)

    @param stdoutToServer: when this is true, the stdout is passed to the debug server

    @param stderrToServer: when this is true, the stderr is passed to the debug server
        so that they are printed in its console and not in this process console.

    @param port: specifies which port to use for communicating with the server (note that the server must be started
        in the same port). @note: currently it's hard-coded at 5678 in the client

    @param suspend: whether a breakpoint should be emulated as soon as this function is called.

    @param trace_only_current_thread: determines if only the current thread will be traced or all current and future
        threads will also have the tracing enabled.

    @param overwrite_prev_trace: deprecated

    @param patch_multiprocessing: if True we'll patch the functions which create new processes so that launched
        processes are debugged.

    @param stop_at_frame: if passed it'll stop at the given frame, otherwise it'll stop in the function which
        called this method.
