"SBDebugger is the primordial object that creates SBTargets and provides
access to them.  It also manages the overall debugging experiences.

For example (from example/disasm.py),::

    import lldb
    import os
    import sys

    def disassemble_instructions (insts):
        for i in insts:
            print i

    ...

    # Create a new debugger instance
    debugger = lldb.SBDebugger.Create()

    # When we step or continue, don't return from the function until the process
    # stops. We do this by setting the async mode to false.
    debugger.SetAsync (False)

    # Create a target from a file and arch
    print('Creating a target for \'%s\'' % exe)

    target = debugger.CreateTargetWithFileAndArch (exe, lldb.LLDB_ARCH_DEFAULT)

    if target:
        # If the target is valid set a breakpoint at main
        main_bp = target.BreakpointCreateByName (fname, target.GetExecutable().GetFilename());

        print main_bp

        # Launch the process. Since we specified synchronous mode, we won't return
        # from this function until we hit the breakpoint at main
        process = target.LaunchSimple (None, None, os.getcwd())

Sometimes you need to create an empty target that will get filled in later.  The most common use for this
is to attach to a process by name or pid where you don't know the executable up front.  The most convenient way
to do this is: ::

    target = debugger.CreateTarget('')
    error = lldb.SBError()
    process = target.AttachToProcessWithName(debugger.GetListener(), 'PROCESS_NAME', False, error)

or the equivalent arguments for :py:class:`SBTarget.AttachToProcessWithID` ."

    "The dummy target holds breakpoints and breakpoint names that will prime newly created targets."

%feature("docstring",
    "Return true if target is deleted from the target list of the debugger."

"Launch a command interpreter session. Commands are read from standard input or
from the input handle specified for the debugger object. Output/errors are
similarly redirected to standard output/error or the configured handles.

@param[in] auto_handle_events If true, automatically handle resulting events.
@param[in] spawn_thread If true, start a new thread for IO handling.
@param[in] options Parameter collection of type SBCommandInterpreterRunOptions.
@param[in] num_errors Initial error counter.
@param[in] quit_requested Initial quit request flag.
@param[in] stopped_for_crash Initial crash flag.

A tuple with the number of errors encountered by the interpreter, a boolean
indicating whether quitting the interpreter was requested and another boolean
set to True in case of a crash.

Example: ::

    # Start an interactive lldb session from a script (with a valid debugger object
    # created beforehand):
    n_errors, quit_requested, has_crashed = debugger.RunCommandInterpreter(True,
        False, lldb.SBCommandInterpreterRunOptions(), 0, False, False)"
