"""Extreme Gradient Boosting.
Extreme Gradient Boosting, which is an efficient implementation of gradient
boosting framework. This package is its R interface. The package includes
efficient linear model solver and tree learning algorithms. The package can
automatically do parallel computation on a single machine which could be
more than 10 times faster than existing gradient boosting packages. It
supports various objective functions, including regression, classification
and ranking. The package is made to be extensible, so that users are also
allowed to define their own objectives easily."""
