%description
Efficient algorithms for fitting the regularization path of linear
regression, GLM, and Cox regression models with grouped penalties.  This
includes group selection methods such as group lasso, group MCP, and group
SCAD as well as bi-level selection methods such as the group exponential
lasso, the composite MCP, and the group bridge.  For more information, see
