def embed(**kwargs):
    """Call this to embed IPython at the current point in your program.

    The first invocation of this will create an :class:`InteractiveShellEmbed`
    instance and then call it.  Consecutive calls just call the already
    created instance.

    If you don't want the kernel to initialize the namespace
    from the scope of the surrounding function,
    and/or you want to load full IPython configuration,
    you probably want `IPython.start_ipython()` instead.

    Here is a simple example::

        from IPython import embed
        a = 10
        b = 20
        embed('First time')
        c = 30
        d = 40
        embed

    Full customization can be done by passing a :class:`Config` in as the
    config argument.
