<h2>DebugClientBase</h2>
<p>
    Class implementing the client side of the debugger.
</p><p>
    It provides access to the Python interpeter from a debugger running in
    another process.
</p><p>
    The protocol between the debugger and the client is based on JSONRPC 2.0
    PDUs. Each one is sent on a single line, i.e. commands or responses are
    separated by a linefeed character.
</p><p>
    If the debugger closes the session there is no response from the client.
    The client may close the session at any time as a result of the script
    being debugged closing or crashing.
</p><p>
    <b>Note</b>: This class is meant to be subclassed by individual
    DebugClient classes. Do not instantiate it directly.
