    """Flexible Mixture Modeling.

    A general framework for finite mixtures of regression models using the EM
    algorithm is implemented. The E-step and all data handling are provided,
    while the M-step can be supplied by the user to easily define new models.
    Existing drivers implement mixtures of standard linear models, generalized
    linear models and model-based clustering."""
