%description
Solves quadratic programming problems where the Hessian is represented as
the product of two matrices. Thanks to Greg Hunt for helping getting this
version back on CRAN. The methods in this package are described in:
Ormerod, Wand and Koch (2008) "Penalised spline support vector
classifiers: computational issues" <doi:10.1007/s00180-007-0102-8>.
