    The idea is that we record the commands sent to the debugger and reproduce them from this script
    (so, this works as the client, which spawns the debugger as a separate process and communicates
    to it as if it was run from the outside)

    Note that it's a python script but it'll spawn a process to run as jython, ironpython and as python.
