"""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."""
